Guideline of Notabilia for the Usage of Plastic Film Capacitors

Plastic film capacitors use organic films for their dielectrics, thus they may fume or flame when damaged by over-voltage or over-current. Please use them within their correct circuit conditions and rated specifications.

1. Circuit Design

• Use capacitors within their characteristic ratings and confirm operating/mounting environments.
• Select the most suitable capacitor for operating conditions.
• Applied voltage (including surge and ripple peak) must not exceed the rated voltage.
• Do not apply current over its permissible level; consider surrounding temperature and self-heating.
• Avoid rapid charge and discharge to prevent degradation or breakdown.

2. Mounting

• Do not apply exceeding tension or torsion to lead wires.
• Mount away from heating parts, high voltage parts, and other components.
• Follow specified soldering conditions strictly.

3. Storing and Handling

• Store indoors at -10+30, <75% RH, avoiding sudden temperature changes, direct sunlight, and corrosive gases.
• Avoid excessive vibration, shock (dropping), and pressure.
