Usage Rules
- Usage Range: Do not exceed the upper category temperature. Avoid overload. Do not exceed maximum pulse current.
- Operation Precautions: Avoid repeated squeezing at the lead wire root. Pay attention to the tip of the lead wires.
- Soldering: Solder heat can transfer to the capacitor core through lead terminals and encapsulation. Be cautious of attenuation or damage due to high temperature and prolonged soldering.
- Wave Soldering: TP 110 for 120 seconds; Ts 120 for 45 seconds. For P 7.5mm, T 4mm, wave soldering time < 4 seconds.
- Soldering Iron: Tip temperature not exceeding 350, time not exceeding 3 seconds.
- Lead wire film capacitors are not suitable for reflow soldering.
Definitions: Ts: Maximum temperature the capacitor body can withstand during wave soldering. Tp: Maximum preheating temperature the capacitor body can withstand.
