Metalized Polypropylene Film EMI Suppression Capacitors - EFX2S Series

The EFX2S series capacitors are designed for EMI suppression and interference filtering in across-the-line applications. Featuring a metalized polypropylene film dielectric, these capacitors offer high capacitance stability, self-healing properties, and over-voltage stress withstanding. They are suitable for use in solar inverters, UPS, AC motor drives, air conditioners, and switch-mode power supplies.
