Key Specifications

This TDK ceramic capacitor boasts a range of attributes that contribute to its superior performance:

Applications: Automotive Grade – This designation signifies that the capacitor is specifically designed and tested to meet the rigorous demands of automotive electronics, including extreme temperatures, vibrations, and electrical transients. This is crucial for systems where failure is not an option, such as engine control units, safety systems, and infotainment.

Brand: TDK – TDK is a renowned Japanese multinational electronics company known for its high-quality electronic components, including capacitors, inductors, and magnetic products. Choosing a TDK component ensures reliability and adherence to strict manufacturing standards.

Feature: AEC-Q200, High MEGA I, Low R – AEC-Q200 certification indicates compliance with the Automotive Electronics Council’s stress test qualification for passive components, guaranteeing suitability for automotive environments. “High MEGA I” suggests excellent insulation resistance, minimizing leakage current and improving efficiency. “Low R” refers to low equivalent series resistance (ESR), which is vital for efficient energy transfer and reduced power loss, especially in high-frequency applications.

AEC-Q200: YES – Explicitly confirming AEC-Q200 compliance, this capacitor is qualified for use in automotive systems, ensuring robust performance under harsh conditions.

Tolerance: ±5% – This indicates the maximum permissible deviation of the actual capacitance value from its nominal value. A ±5% tolerance is considered precise for many applications, ensuring consistent circuit behavior.

L x W Size: 5.7mm x 5.0mm [EIA 2220] – This specifies the physical dimensions of the capacitor. The EIA 2220 package size is a relatively large surface-mount device (SMD) footprint, suitable for applications requiring higher capacitance values or voltage ratings while still offering space efficiency compared to through-hole components.

Capacitance: 20nF – The nominal capacitance value of 20 nanofarads (nF) determines the amount of charge the capacitor can store. This value is suitable for various filtering, coupling, and timing applications.

T(Max.) / mm: 6.9 – This refers to the maximum thickness of the component, which is important for PCB layout and enclosure design, ensuring adequate clearance.

Temp. Chara.: C0G – C0G is a highly stable dielectric material (Class I) with excellent temperature stability. It exhibits negligible change in capacitance over a wide temperature range, making it ideal for precision applications where capacitance drift must be minimized.

Component Type: Ceramic Capacitor (MLCC) – This identifies the fundamental type of component. Multi-Layer Ceramic Capacitors (MLCCs) are widely used due to their small size, high capacitance density, and excellent high-frequency characteristics.

Product Status: Production – This indicates that the component is actively being manufactured and is readily available for purchase, ensuring long-term supply for new designs and existing products.

Rated Voltage [DC] / V: 1000 – This is the maximum DC voltage that can be continuously applied across the capacitor without causing damage. A 1000V rating makes this capacitor suitable for high-voltage applications, providing a significant safety margin in many automotive and industrial systems.

Cap. Change or Temp. Coef.: 0±30ppm/°C – This specifies the temperature coefficient of capacitance. A value of 0±30ppm/°C (parts per million per degree Celsius) is exceptionally low, highlighting the C0G dielectric’s superior stability and minimal capacitance variation with temperature changes.

Operating Temp. Range / °C: -55 to 125 – This broad operating temperature range signifies the capacitor’s ability to function reliably in extreme thermal environments, a critical requirement for automotive and industrial applications.
