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 designed and tested to meet the rigorous demands of commercial electronic products, ensuring reliability and longevity in standard operating environments, as opposed to automotive or industrial-specific grades.

Brand: TDK – TDK is a renowned Japanese multinational electronics company, recognized globally for its high-quality electronic components, including capacitors, inductors, and magnetic products. Their brand signifies a commitment to innovation and manufacturing excellence.

Feature: Soft – The “Soft” feature typically refers to a soft termination type, which helps to mitigate mechanical stress on the capacitor, reducing the risk of cracking due to board flexure or thermal cycling. This enhances the component’s durability and reliability in demanding assembly or operational conditions.

Tolerance: ±10% – This specifies the permissible deviation of the actual capacitance value from its nominal value. A ±10% tolerance is common for general-purpose applications where precise capacitance is important but not ultra-critical, providing a good balance between performance and cost.

L x W Size: 2.0mm x 1.25mm [EIA 0805] – This indicates the physical dimensions of the capacitor. The 0805 EIA (Electronic Industries Alliance) standard package size is widely used in surface-mount technology (SMT) for its balance of compactness and ease of handling during automated assembly. This size allows for high-density circuit board designs.

Capacitance: 4.7μF – This is the primary electrical characteristic, representing the capacitor’s ability to store charge. A capacitance of 4.7 microfarads is substantial for an MLCC of this size, making it suitable for decoupling, filtering, and energy storage in power supply lines and signal paths.

T(Max.) / mm: 1.5 – This refers to the maximum thickness of the component, which is 1.5mm. This dimension is crucial for mechanical design considerations, especially in thin or space-constrained electronic devices.

Temp. Chara.: X7R – X7R is a common dielectric material for ceramic capacitors, known for its stable capacitance over a broad temperature range. It offers a capacitance change of ±15% from -55°C to +125°C, making it suitable for applications that experience significant temperature fluctuations.

Product Status: Production – This confirms that the component is actively being manufactured and is readily available for new designs and existing production runs, ensuring long-term supply stability.

Rated Voltage [DC] / V: 16 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage or degradation. A 16V rating is common for low-voltage digital and analog circuits, including those powered by 3.3V, 5V, or 12V supplies.

Cap.Change or Temp.Coef.: ±15% – This reiterates the capacitance stability over temperature, specifically for the X7R dielectric. It means that the capacitance value will not deviate by more than ±15% from its nominal value across the specified operating temperature range.

Operating Temp. Range / °C: -55 to 125 – This wide operating temperature range signifies the capacitor’s robustness and suitability for harsh environments, from extreme cold to high heat, ensuring reliable performance in diverse climatic conditions.
