How to use

Install the capacitor according to the circuit design, observing polarity is not required for film capacitors. Mount the component securely to avoid mechanical stress on leads or terminals and ensure adequate clearance from heat sources. Verify the rated voltage and capacitance match the circuit requirements; use a correct mounting orientation for safe ventilation and to minimize exposure to vibration. When replacing an existing part, confirm the physical size and lead spacing are compatible with the board or chassis layout.

Usage recommendations

Operate the capacitor within its rated voltage and temperature range, and avoid prolonged exposure to temperatures or voltages beyond specifications. Use appropriate surge protection and fusing in mains-connected circuits. For critical or safety-related applications, follow applicable standards and perform validation testing in the intended environment.
