C1812C334KCRAC7210 Description

Short technical summary and product information.

The KEMET C1812C334KCRAC7210 is a surface-mount multilayer ceramic capacitor (MLCC) from the SMD Comm X7R HV series. It offers a capacitance of 0.33 µF with ±10% tolerance and a rated DC voltage of 500 V. The dielectric is X7R, providing a capacitance change of no more than 15% over the temperature range of -55°C to +125°C.

Key electrical characteristics include a dissipation factor of 2.5% maximum at 1 kHz, insulation resistance of 303 MOhms minimum, and an aging rate of 3% per decade hour. The component is designed for general purpose applications where high voltage and temperature stability are required.

The capacitor is housed in an 1812 (4532 metric) case with a maximum thickness of 2.30 mm. Termination is tin, and the part is rated MSL 1 (unlimited floor life). It is supplied in tape and reel packaging (330 mm plastic tape) with a standard quantity of 2000 pieces per reel.
