Key Specifications

This TDK ceramic capacitor boasts a comprehensive set of specifications tailored for demanding applications. The ‘Apps.’ attribute, explicitly stating “Automotive Grade,” signifies that this component is designed, tested, and qualified for use in automotive electronics, where reliability and performance under harsh conditions are paramount. The “Brand” is TDK, a testament to its quality and engineering excellence. A key “Feature” is its AEC-Q200 qualification, which is further confirmed by “AEC-Q200: YES.” This certification is a critical standard for passive components used in automotive applications, ensuring high reliability and performance under various environmental stresses. The “Tolerance” of ±5% indicates a precise capacitance value, crucial for applications requiring tight control over circuit parameters. Its physical “L x W Size” of 5.7mm x 5.0mm, corresponding to the EIA 2220 package, denotes a relatively larger surface-mount form factor, often associated with higher capacitance or voltage ratings. The “Capacitance” of 30nF (nanofarads) provides significant charge storage capability for filtering and decoupling. The maximum thickness “T(Max.) / mm” of 6.9mm is important for PCB layout and enclosure design. The “Temp. Chara.” of C0G is a highly stable dielectric material, known for its minimal change in capacitance over a wide temperature range, as further detailed by “Cap.Change or Temp.Coef.: 0±30ppm/°C.” This ultra-stable characteristic is vital for precision circuits where temperature variations must not affect performance. The “Component Type” is clearly a Ceramic Capacitor (MLCC), and its “Product Status” is “Production,” indicating it is actively manufactured and available. A high “Rated Voltage [DC] / V” of 1250V makes it suitable for high-voltage applications, providing a robust safety margin. Finally, an “Operating Temp. Range / °C” of -55 to 125°C highlights its ability to function reliably in extreme thermal environments, typical of automotive under-the-hood or industrial settings.
