Usage Rules
Usage Scope:
- Do not exceed the upper category temperature during use.
- Avoid overload operation.
- Do not exceed the maximum pulse current during use.
Operation Precautions:
- Avoid repeatedly squeezing the base of the leads.
- Pay attention to the tip of the leads.
Soldering:
Soldering heat can transfer to the capacitor core through the lead terminals and encapsulation layer. Be cautious of capacitance electrical characteristic attenuation or damage caused by high temperature and prolonged soldering.
- Wave Soldering: TP110 for 120 seconds; Ts120 for 45 seconds. For P7.5mm, T4mm: Wave soldering time 4 seconds.
- Soldering Iron: Tip temperature should not exceed 350, and soldering time should not exceed 3 seconds.
- Lead-type film capacitors are not suitable for reflow soldering.
Ts: Maximum temperature the component body can withstand during wave soldering.
Tp: Maximum temperature the component body can withstand during the preheating stage.
