Usage Guidelines

Plastic Film Capacitors Use Precautions:

Plastic film capacitors use organic films as dielectrics. When subjected to over-voltage or over-current, they may fume or flame, leading to damage. Ensure proper circuit design and operating conditions.

1. Circuit Design:

• Use capacitors within their specified ratings and operating environments.
• Select the most suitable capacitor for your operating conditions.
• Applied voltage (including surge and ripple peak) must not exceed the rated voltage.
• Do not exceed the permissible current level; consider ambient and self-temperature rise.
• Avoid rapid charge and discharge, which can degrade characteristics or cause breakdown.

2. Mounting:

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

3. Storing and Handling:

• Store indoors at -10 to +30 with relative humidity under 75%, avoiding sudden temperature changes, direct sunlight, and corrosive gases.
• Avoid excessive vibration, shock (dropping), and pressure.
• For storage exceeding 12 months, re-check capacitor characteristics before production and use.
