Product Overview
The DGCX X2 series of metallized polypropylene film capacitors are designed for suppressing electromagnetic interference (EMI) in power supply applications. These capacitors feature a non-inductive, metallized polypropylene film structure with excellent self-healing properties and the ability to withstand high voltage surges. Encased in a flame-retardant plastic shell (UL94V-0) and sealed with flame-retardant epoxy resin, they are suitable for interference suppression and X-class cross-line capacitor circuits where failure does not pose a risk of electric shock. They are not recommended for use in capacitive power supplies or high-temperature/high-humidity environments without specific consultation.

Usage Rules
Application Scope: Do not exceed the upper limit category temperature. Avoid overload use. Do not exceed the maximum pulse current during use.
Handling Precautions: Avoid repeated squeezing at the lead root. Be mindful of the lead tip.
Soldering: Solder heat can transfer through leads and encapsulation to the capacitor core. Pay attention to the attenuation or damage of electrical characteristics caused by high temperature and prolonged soldering.
- Wave Soldering: TP110; Ts120, 45s. For polypropylene film capacitors: P7.5mm, T4mm, wave soldering time < 4 seconds.
- Soldering Iron: Tip temperature should not exceed 350, soldering time should not exceed 3 seconds.
- Film capacitors with printed leads are not suitable for reflow soldering.
Definitions: Ts: Maximum temperature the capacitor body can withstand during preheating. Tp: Maximum temperature the capacitor body can withstand during the preheating stage.
