Key Specifications

This TDK ceramic capacitor boasts several critical specifications that define its performance and suitability for various applications:

Applications: Commercial Grade – This designation indicates that the capacitor is designed and tested to meet the requirements of general commercial electronic devices, ensuring reliable operation in a wide range of everyday products, from consumer electronics to industrial controls, where extreme environmental conditions are not typically encountered.

Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components. Choosing a TDK component assures engineers of robust design, stringent quality control, and consistent performance, backed by decades of manufacturing expertise.

Feature: General – This describes the capacitor as a standard, versatile component suitable for a broad spectrum of general-purpose circuit functions, rather than being specialized for a niche application like high-frequency RF or high-voltage power supplies. It implies a balanced performance profile for common electronic needs.

Tolerance: ±10% – This specifies the permissible deviation of the actual capacitance value from its nominal value (1.5μF). A ±10% tolerance is standard for many general-purpose applications, indicating that the capacitance will fall between 1.35μF and 1.65μF, which is acceptable for most filtering and timing circuits.

Capacitance: 1.5μF – This is the primary electrical parameter, representing the capacitor’s ability to store an electrical charge. A 1.5μF capacitance is a relatively high value for a ceramic capacitor, making it suitable for applications requiring significant energy storage or effective low-frequency filtering.

F(Nom.) / mm: 5, L(Max.) / mm: 5.5, T(Max.) / mm: 3.5, W(Max.) / mm: 6 – These dimensions (nominal length of the body, maximum length, maximum thickness, and maximum width respectively) are crucial for mechanical design and PCB layout. They ensure that the component fits correctly on the circuit board and within the product enclosure, facilitating proper spacing and assembly.

Temperature Characteristic: X5R – X5R is an EIA (Electronic Industries Alliance) designation for ceramic capacitors, indicating its capacitance change over a specific temperature range. For X5R, the capacitance change is within ±15% from its nominal value over an operating temperature range of -55°C to +85°C. This characteristic makes it suitable for applications where moderate temperature stability is required, common in commercial and industrial environments.

Component Type: Ceramic Capacitor (Leaded MLCC) – This explicitly identifies the component as a multilayer ceramic capacitor with leads, distinguishing it from surface-mount (SMD) MLCCs or other capacitor types like electrolytic or film. Leaded components are preferred for their mechanical robustness and ease of manual assembly or through-hole soldering.

Product Status: Production (NRND) – “Not Recommended for New Designs” (NRND) indicates that while the product is still in production and available for existing designs, it is not advised for inclusion in new product developments. This often suggests that newer, potentially more efficient or cost-effective alternatives are available, or the product may eventually be phased out. However, it remains fully supported for current users.

Rated Voltage [DC] / V: 25 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or premature failure. A 25V rating makes this capacitor suitable for low-voltage power supplies, signal processing circuits, and various battery-powered devices.

Lead Length / Package Type: Taping – “Taping” refers to the packaging method where components are supplied on a continuous tape, typically for automated assembly processes using pick-and-place machines. This ensures consistent lead length and orientation, facilitating efficient manufacturing.

Features and Benefits

• Robust Leaded Design: The through-hole leaded configuration provides superior mechanical stability and vibration resistance compared to surface-mount components, making it ideal for applications requiring durability.
• High Capacitance in Compact Size: With 1.5μF capacitance, this TDK capacitor offers significant charge storage capability within relatively small dimensions, optimizing PCB space without compromising performance.
• Stable X5R Temperature Characteristic: The X5R dielectric ensures reliable performance across a broad commercial temperature range (-55°C to +85°C) with predictable capacitance variation, suitable for general-purpose electronics.
• TDK Quality and Reliability: Manufactured by TDK, a leader in passive components, users benefit from consistent quality, high reliability, and adherence to industry standards, reducing the risk of component failure.
• Versatile Commercial Grade: Designed for commercial applications, it provides a cost-effective yet dependable solution for a wide array of electronic devices, balancing performance with economic viability.

Typical Applications

The FK26X5R1E155KN006 ceramic capacitor’s specifications make it highly versatile for numerous electronic applications:

1. Power Supply Decoupling and Filtering: In DC-DC converters and linear regulators, this capacitor is excellent for decoupling power rails, reducing noise, and stabilizing voltage. Its 1.5μF capacitance can effectively filter out ripple and transient spikes, ensuring clean power delivery to sensitive ICs and microcontrollers.

2. Signal Coupling and Bypass: In audio circuits or low-frequency signal processing, it can be used for AC coupling, allowing AC signals to pass while blocking DC bias, or for bypassing unwanted high-frequency noise to ground, improving signal integrity.

3. Timing Circuits: While not as precise as film capacitors for critical timing, its 1.5μF capacitance and ±10% tolerance make it suitable for non-critical RC timing circuits in applications like simple oscillators, delays, or debouncing circuits where exact timing is not paramount.

4. General Purpose Filtering: Across various electronic devices, it can serve as a general filter for input/output lines, suppressing electromagnetic interference (EMI) and radio-frequency interference (RFI), contributing to overall system stability and compliance.

5. Automotive Infotainment and Body Electronics: Although commercial grade, its robust leaded design and X5R characteristics can find use in less critical automotive applications such as infotainment systems, power window controls, or lighting modules, where moderate temperature stability and mechanical resilience are required.

In summary, the FK26X5R1E155KN006 from TDK is a reliable and versatile 1.5μF X5R ceramic capacitor, ideal for a broad range of commercial-grade electronic designs. Its robust leaded package, combined with TDK’s manufacturing excellence, ensures dependable performance for filtering, decoupling, and general circuit functions.
