Key Specifications

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

Apps. (Commercial Grade): This designation indicates that the capacitor is engineered for use in general commercial electronics, where reliability and cost-effectiveness are balanced. It is suitable for a broad spectrum of products, from consumer electronics to industrial control systems, but not typically for highly specialized, mission-critical applications like automotive or medical life support where AEC-Q200 or similar stringent qualifications are mandatory.

Brand (TDK): TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components. Specifying TDK assures buyers of a product manufactured to exacting standards, backed by extensive research and development, and a reputation for durability and performance.

Feature (General): This attribute signifies that the capacitor is designed for general-purpose applications, offering a balanced set of electrical characteristics without being optimized for a specific, niche function. It provides a versatile solution for common capacitance requirements.

Tolerance (±10%): The capacitance value of this component is guaranteed to be within ±10% of its nominal value. This tolerance level is standard for many general-purpose ceramic capacitors and is acceptable for applications where precise capacitance is not overly critical, such as decoupling, filtering, and timing circuits.

Capacitance (2.2μF): With a capacitance of 2.2 microfarads, this capacitor can store a significant amount of charge, making it suitable for applications requiring substantial energy storage or effective low-frequency filtering. This value is commonly used in power supply smoothing, audio coupling, and timing circuits.

F(Nom.) / mm (5), L(Max.) / mm (4.5), T(Max.) / mm (2.5), W(Max.) / mm (5.5): These dimensions refer to the nominal lead spacing (F), maximum length (L), maximum thickness (T), and maximum width (W) of the capacitor body. Understanding these physical dimensions is crucial for PCB layout design, ensuring proper fit and mechanical compatibility within the intended electronic assembly.

Temp. Chara. (X7R): X7R is a common ceramic dielectric material known for its relatively stable capacitance over a wide temperature range. It typically maintains its capacitance within ±15% from -55°C to +125°C, making it suitable for applications that experience varying ambient temperatures without significant performance degradation.

Component Type (Ceramic Capacitor (Leaded MLCC)): This clearly identifies the component as a Multi-Layer Ceramic Capacitor with leads, distinguishing it from surface-mount (SMD) MLCCs or other capacitor types like electrolytic or film capacitors. Leaded components are preferred for prototypes, manual assembly, and applications requiring greater mechanical robustness.

Product Status (Production(NRND)): ‘Production’ indicates that the component is actively being manufactured. ‘NRND’ stands for ‘Not Recommended for New Designs,’ suggesting that while the part is still available, TDK may have newer, improved, or more cost-effective alternatives. For long-term projects, it’s advisable to consider the implications of NRND status.

Rated Voltage [DC] / V (25): This capacitor is rated for a maximum DC voltage of 25 Volts. It is imperative that the operating voltage in any circuit does not exceed this rating to prevent dielectric breakdown and component failure. This voltage rating makes it suitable for many low-voltage digital and analog circuits.

Lead Length / Package Type (7mm for Bulk): The leads are 7mm long, which is a common length for through-hole components, allowing for easy insertion into PCBs and subsequent soldering. The ‘Bulk’ packaging indicates that these capacitors are supplied loose, which is ideal for manual assembly or automated processes using vibratory feeders.

Features and Benefits

• Reliable TDK Quality: Manufactured by TDK, ensuring high standards of quality, consistency, and long-term reliability in commercial applications.
• Stable X7R Dielectric: Offers excellent capacitance stability over a broad temperature range (-55°C to +125°C), minimizing performance variations in fluctuating thermal environments.
• Versatile 2.2μF Capacitance: Provides significant charge storage and filtering capabilities suitable for a wide array of general-purpose electronic circuit designs.
• Robust Leaded Design: Ideal for through-hole mounting, offering superior mechanical strength and ease of handling compared to surface-mount devices, particularly in environments subject to vibration or stress.
• 25V DC Rating: Sufficient voltage handling for common low-voltage digital and analog circuits, providing a safe operating margin for many applications.

Typical Applications

The FK24X7R1E225KR000 ceramic capacitor finds extensive use across various electronic sectors due to its robust design and stable electrical characteristics:

Power Supply Decoupling: In power supply circuits, this capacitor is frequently used to decouple integrated circuits (ICs) from the power rail. Its 2.2μF capacitance helps to smooth out voltage fluctuations and suppress high-frequency noise, ensuring stable power delivery to sensitive digital and analog components, thereby preventing malfunctions and improving overall system reliability.

General-Purpose Filtering: The capacitor’s ability to block DC while passing AC signals makes it excellent for filtering applications. It can be employed in low-pass, high-pass, or band-pass filter circuits to remove unwanted frequency components from signals, crucial in audio processing, sensor interfaces, and communication systems.

Timing Circuits: In conjunction with resistors, this 2.2μF capacitor can form RC timing circuits, which are fundamental in oscillators, timers, and delay lines. Its stable X7R dielectric ensures consistent timing performance over varying temperatures, critical for applications like microcontrollers and sequential logic.

Signal Coupling and Decoupling: Used in audio amplifiers and other analog circuits, it can couple signals between stages, blocking DC bias while allowing the AC signal to pass. Conversely, it can decouple stages to prevent unwanted signal interaction, maintaining signal integrity and reducing crosstalk.

LED Lighting Drivers: In LED driver circuits, this capacitor can be used for input filtering, output smoothing, and transient suppression, contributing to the stable operation and longevity of LED lighting systems by ensuring a clean power supply to the driver ICs.

In summary, the FK24X7R1E225KR000 TDK ceramic capacitor is a versatile and reliable component for a wide range of commercial electronic applications.
