Key Specifications

• Apps. (Commercial Grade): This designation indicates that the FK26X7R2A684KN006 capacitor is engineered for use in general-purpose electronic equipment, consumer electronics, and industrial applications where standard reliability and performance are required, rather than specialized high-reliability or automotive-grade components.
• Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and other passive devices. Choosing a TDK component ensures adherence to stringent manufacturing standards and reliable performance.
• Feature (Mid): The ‘Mid’ feature likely refers to the capacitor’s overall performance characteristics, positioning it as a balanced option in terms of capacitance, voltage, and temperature stability, suitable for a broad spectrum of applications without being overly specialized or basic.
• Tolerance (±10%): This specification indicates the permissible deviation of the actual capacitance value from the nominal 680nF. A ±10% tolerance is common for general-purpose ceramic capacitors, providing sufficient accuracy for most commercial and industrial circuit designs.
• Capacitance (680nF): The capacitance value of 680 nanofarads (0.68 microfarads) defines the component’s ability to store electrical charge. This value is suitable for various filtering, decoupling, and timing applications in moderate frequency ranges.
• F(Nom.) / mm (5): This refers to the nominal lead pitch or lead spacing, which is 5mm. This standard spacing facilitates easy integration into printed circuit boards (PCBs) designed for through-hole components.
• L(Max.) / mm (5.5): The maximum length of the capacitor body is 5.5mm. This dimension is critical for PCB layout and ensuring proper fit within an enclosure.
• T(Max.) / mm (3.5): The maximum thickness of the capacitor body is 3.5mm. This dimension, along with length and width, helps in determining the component’s footprint and vertical clearance requirements on a PCB.
• Temp. Chara. (X7R): X7R is a common dielectric material for ceramic capacitors, known for its stable performance across a wide temperature range. It offers a capacitance change of no more than ±15% over an operating temperature range of -55°C to +125°C, making it suitable for applications requiring moderate temperature stability.
• W(Max.) / mm (6): The maximum width of the capacitor body is 6mm. This dimension is important for physical layout and spacing on a PCB.
• Component Type (Ceramic Capacitor (Leaded MLCC)): This specifies the fundamental type of capacitor. Leaded MLCCs combine the benefits of multilayer ceramic technology (high capacitance in a small size) with through-hole leads for robust mechanical attachment and ease of manual assembly or rework.
• Product Status (Production(NRND)): ‘Production (NRND)’ means the component is currently in active production but is ‘Not Recommended for New Designs’. While available for existing designs, engineers should consider newer alternatives for future projects to ensure long-term supply and support.
• Rated Voltage [DC] / V (100): The capacitor is rated for a maximum DC voltage of 100 Volts. This is the highest continuous DC voltage that can be applied across the capacitor without causing damage or premature failure. It is crucial to select a capacitor with a rated voltage significantly higher than the maximum expected operating voltage in the circuit.
• Lead Length / Package Type (Taping): ‘Taping’ indicates that the component is supplied on tape, which is a common packaging method for automated assembly (e.g., with radial lead insertion machines). This ensures efficient handling and placement in manufacturing processes.

Features and Benefits

• Reliable X7R Dielectric: The X7R temperature characteristic ensures stable capacitance performance across a broad operating temperature range (-55°C to +125°C), making it suitable for diverse environmental conditions without significant performance degradation.
• High Capacitance in a Compact Form: With 680nF capacitance in a relatively small form factor (5.5mm L x 6mm W x 3.5mm T), this Leaded MLCC offers efficient space utilization on PCBs while providing substantial charge storage capabilities.
• Robust Through-Hole Mounting: The leaded design allows for secure through-hole mounting, providing excellent mechanical stability and vibration resistance compared to surface-mount components, which is beneficial in applications subject to physical stress.
• TDK Quality and Consistency: Manufactured by TDK, a trusted name in electronics, this capacitor benefits from stringent quality control and advanced manufacturing processes, ensuring high reliability and consistent electrical characteristics.
• Versatile Commercial Grade Application: Designed for commercial-grade applications, it offers a cost-effective yet reliable solution for general electronics, consumer devices, and industrial control systems.

Typical Applications

• Power Supply Decoupling: The FK26X7R2A684KN006 is ideal for decoupling power supply lines, filtering out high-frequency noise and stabilizing voltage rails for integrated circuits and other sensitive components. Its 680nF capacitance provides effective energy storage to smooth out transient voltage drops.
• Signal Filtering: In audio circuits, communication systems, and sensor interfaces, this capacitor can be used in low-pass, high-pass, or band-pass filter configurations to selectively pass or block certain frequency ranges, improving signal integrity and reducing interference.
• Timing Circuits: Its stable capacitance and ±10% tolerance make it suitable for use in RC timing circuits, oscillators, and delay lines where precise timing is required, such as in microcontrollers or industrial control systems.
• Bypassing Applications: The capacitor can bypass unwanted AC signals to ground, preventing them from interfering with DC power lines or sensitive components. This is crucial in preventing noise propagation within complex electronic systems.
• General Purpose Coupling: It can be employed as a coupling capacitor to block DC voltage while allowing AC signals to pass between different stages of an amplifier or signal processing circuit, ensuring proper signal transfer without DC bias interference.
