Product Overview
The CL21(H)/MPE series are metallized polyester film capacitors (impregnated type) designed for DC filtering applications in electronic equipment, such as PFC and DC link circuits. These capacitors feature a non-inductive winding structure, small size, good self-healing properties, and are encapsulated with flame-retardant epoxy resin powder. They are widely used in LED drivers, switching power supplies, electronic ballasts, and inverters.

Usage Rules
Usage Scope: Do not exceed the upper category temperature, avoid overload, and do not exceed the maximum pulse current.
Operation Notes: Avoid repeated squeezing at the lead root, be careful of lead tips.
Soldering: Solder heat can transfer to the capacitor core. Ensure solder temperature is within the following ranges:
- Wave Soldering: TP 125 for 120 sec; Ts 160 for 45 sec.
- Soldering Iron: Tip temperature not exceeding 350 for no more than 3 seconds.
- Not suitable for reflow soldering.
Maximum Effective Current vs. Frequency Curve
Note: Curves are typical values under sinusoidal voltage, ambient temperature 85, and internal temperature rise T=10. CL21(H) series is for DC filtering and DC module circuits only, with unidirectional ripple voltage. Not for AC circuits. Consult technical staff for any doubts.
