Product Description
Product Overview
This X2 metallized polypropylene film capacitor is designed for EMI suppression in power supplies. It features a non-inductive winding structure with self-healing properties, capable of withstanding high voltage surges. Encased in a flame-retardant plastic shell and epoxy resin, it is suitable for interference suppression and X-capacitor circuits where capacitor failure does not pose a shock hazard. It is not recommended for capacitive power supply or high-temperature/high-humidity applications.

Usage Rules
Usage Scope:
- Do not exceed the upper limit category temperature.
- Avoid overload operation.
- Do not exceed the maximum pulse current during use.
Operation Precautions:
- Avoid repeatedly squeezing the base of the lead wires.
- Be cautious of the tips of the lead wires.
Soldering:
- Soldering heat can transfer through lead terminals and encapsulation layers to the capacitor core. Be mindful of potential degradation or damage from high temperatures and prolonged soldering times.
- Recommended Soldering Temperatures:
- Wave Soldering: TP110; Ts120, 45s. For polypropylene film capacitors (P7.5mm, T4mm), wave soldering time < 4 seconds.
- Soldering Iron: Tip temperature not exceeding 350, welding time not exceeding 3 seconds.
- Capacitors with printed lines are not suitable for reflow soldering.
Note: TP: Maximum temperature the capacitor body can withstand during the preheating stage. Ts: Maximum temperature the capacitor body can withstand during wave soldering.
