Film Capacitors: Electronic Equipment Use

Electronic Equipment Use design engineers Panasonic

Low-ESR, No Shock or Audible Noise and No Piezoelectric Effect

Panasonic Film Capacitors offer stable capacitance and temperature characteristics, tight tolerances, low-ESR and low dissipation factors. Available in Surface-Mount (SMT) and radial leaded types, including Metallized Polypropylene Class X2 Capacitors. Functionality offered in the Film Capacitor product line for Electronic Equipment Use include high temperature and high reliability without shock noise, piezoelectric effect and audible noise.

Film Capacitors for MLCC Replacement

The Film Capacitor product line features many suggested MLCC Alternative Series, which include ECW-U(C), ECW-U(X), ECH-U(X), ECH-U(C), ECW-U(V16), and ECP-U(A).
