Key Specifications

The FA18C0G1H122JNU00 boasts several critical specifications that define its performance and suitability for specific applications. Its Capacitance of 1.2nF (nanofarads) indicates its ability to store charge, a value suitable for high-frequency filtering, coupling, and decoupling applications. The Tolerance of ±5% signifies the precision of this capacitance value, ensuring consistent performance across manufactured units, which is crucial for sensitive circuits. The Rated Voltage [DC] / V of 50V specifies the maximum DC voltage that can be continuously applied across the capacitor without breakdown, making it suitable for standard automotive 12V or 24V systems with ample safety margin. The Temp. Chara. of C0G is a highly stable dielectric material, indicating minimal change in capacitance over a wide temperature range (-55°C to +125°C typically), which is vital for applications requiring precise timing or filtering in varying thermal conditions. The physical dimensions, including L(Max.) / mm of 4mm, W(Max.) / mm of 5.5mm, and T(Max.) / mm of 2.5mm, define its maximum length, width, and thickness, respectively, aiding in PCB layout and mechanical integration. The F(Nom.) / mm of 2.5mm likely refers to the nominal lead spacing, crucial for through-hole mounting. The Lead Length / Package Type is specified as 7mm for Bulk, providing sufficient length for soldering and ensuring compatibility with automated insertion processes. The AEC-Q200 qualification (YES) is a paramount attribute, confirming that this component meets the stringent reliability standards required for automotive electronics, including tests for temperature cycling, vibration, and humidity.
