Key Specifications

This section details the critical attributes of the FK18X7R0J155KR006, providing context for their importance in circuit design:

• Apps.: Commercial Grade: This designation indicates that the capacitor is designed and tested for use in standard commercial electronic equipment, where reliability and performance are key but extreme environmental conditions (like those in automotive or military applications) are not typically encountered. It signifies a balance of cost-effectiveness and robust functionality.
• Brand: TDK: TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and sensors. Specifying TDK ensures a product from a reputable manufacturer with a history of innovation and reliability in the electronics industry.
• Feature: General: This attribute suggests that the capacitor is designed for general-purpose applications, implying it is versatile and can be used in a wide array of circuits without highly specialized characteristics. It’s a workhorse component suitable for many common filtering, bypassing, and coupling tasks.
• Tolerance: ±10%: The capacitance tolerance specifies the permissible deviation from the nominal capacitance value. A ±10% tolerance is standard for many general-purpose ceramic capacitors, indicating that the actual capacitance will be within 10% higher or lower than the stated 1.5µF. This level of precision is acceptable for most non-critical timing or frequency-sensitive applications.
• Capacitance: 1.5µF: This is the primary electrical characteristic, representing the capacitor’s ability to store charge. A capacitance of 1.5 microfarads (µF) is a relatively high value for a ceramic capacitor, making it suitable for applications requiring significant energy storage, such as power supply decoupling, low-frequency filtering, or bulk energy storage in compact designs.
• F(Nom.) / mm: 2.5: This likely refers to the nominal lead pitch or spacing between the leads, which is 2.5 mm. This dimension is crucial for PCB layout and ensures compatibility with standard through-hole component footprints.
• L(Max.) / mm: 4: The maximum length of the capacitor body is 4 mm. This physical dimension is important for mechanical design and ensuring the component fits within the allocated space on a PCB.
• T(Max.) / mm: 2.5: The maximum thickness (or height) of the capacitor body is 2.5 mm. This dimension is critical for overall product height constraints, especially in compact enclosures.
• Temp. Chara.: X7R: X7R is a common dielectric material for ceramic capacitors, known for its stable capacitance over a wide temperature range, typically from -55°C to +125°C. The capacitance change is limited to ±15% over this range, making it ideal for applications where temperature stability is important but not as critical as C0G/NP0 dielectrics.
• W(Max.) / mm: 5.5: The maximum width of the capacitor body is 5.5 mm. Along with length and thickness, this dimension completes the physical footprint information necessary for mechanical integration.
• Component Type: Ceramic Capacitor (Leaded MLCC): This explicitly defines the component’s construction. Leaded MLCCs offer advantages in terms of mechanical robustness, ease of manual soldering, and suitability for applications requiring higher power dissipation or where surface mount technology (SMT) is not feasible.
• Product Status: Production(NRND): “Production (NRND)” stands for “Not Recommended for New Designs.” This status indicates that while the component is currently in production and available, the manufacturer recommends using newer alternatives for new product developments. This is important for long-term product planning and obsolescence management.
• Rated Voltage [DC] / V: 6.3: This is the maximum DC voltage that can be continuously applied across the capacitor without risk of dielectric breakdown. A 6.3V rating is common for low-voltage digital and analog circuits, often found in battery-powered devices or systems operating from 3.3V or 5V rails, providing a sufficient safety margin.
• Lead Length / Package Type: Taping: “Taping” refers to the packaging method, where components are supplied on a continuous tape, typically for automated assembly processes (e.g., with radial lead insertion machines). This facilitates efficient manufacturing and handling.

Features and Benefits

• Stable Performance with X7R Dielectric: The X7R temperature characteristic ensures that the 1.5µF capacitance remains relatively stable (within ±15%) across a broad operating temperature range of -55°C to +125°C. This stability is crucial for maintaining circuit performance in varying environmental conditions, reducing the need for temperature compensation.
• Robust Leaded MLCC Construction: As a leaded multi-layer ceramic capacitor, the FK18X7R0J155KR006 offers enhanced mechanical stability and vibration resistance compared to surface-mount counterparts. The leads provide a strong physical connection to the PCB, making it suitable for applications where physical stress or manual assembly is a factor.
• High Capacitance in a Compact Form Factor: With a capacitance of 1.5µF and a maximum body size of 4mm (L) x 5.5mm (W) x 2.5mm (T), this capacitor provides substantial energy storage in a relatively small package. This makes it ideal for space-constrained designs that require effective filtering and decoupling.
• Reliable TDK Quality: Manufactured by TDK, a leader in passive components, this capacitor benefits from stringent quality control and advanced manufacturing processes. This ensures consistent performance, long-term reliability, and adherence to industry standards, reducing the risk of component failure in end products.
• Versatile Commercial Grade Application: Designed for commercial-grade applications, this capacitor is a cost-effective yet reliable solution for a wide range of electronic products. Its general-purpose features make it adaptable to various circuit functions, simplifying component selection and inventory management.

Typical Applications

• Power Supply Decoupling and Filtering: The 1.5µF capacitance and 6.3V rating make this capacitor excellent for decoupling power rails in low-voltage digital and analog circuits. It helps to suppress voltage fluctuations and high-frequency noise, ensuring stable power delivery to integrated circuits and improving overall system performance.
• Signal Coupling and Bypass Circuits: In audio and signal processing applications, the FK18X7R0J155KR006 can be used for AC coupling to block DC components while allowing AC signals to pass, or for bypassing unwanted AC signals to ground. Its stable capacitance ensures reliable signal integrity.
• Timing and Oscillator Circuits: While not as precise as C0G/NP0 types, the X7R dielectric’s relatively stable capacitance can be suitable for less critical timing circuits, RC oscillators, and delay lines where a ±10% tolerance is acceptable, contributing to the overall functionality of control systems.
• General-Purpose Filtering in Consumer Electronics: From home appliances to personal gadgets, this capacitor can be found in various consumer electronics for general filtering tasks, ensuring smooth operation and reducing electromagnetic interference (EMI) in power lines and signal paths.
• Industrial Control Systems: In industrial environments where robust components are preferred for through-hole mounting, this leaded ceramic capacitor can be used in control boards, sensor interfaces, and data acquisition systems for noise suppression and voltage stabilization, contributing to the reliability of automation equipment.
