Comparison of Impedance


WIMA MKS 02 / 0.1µF/ PCM 2.5mm
Z = f(f) / f(T)
-20° to +85°C

(also applicable for size code 1812)


WIMA MKS 2 / 0.1µF/ PCM 5mm
Z = f(f) / f(T)
-20° to +85°C

(also applicable for size code 2220)

Ceramic X7R / PCM 5mm
Z = f(f) / f(T)
-20° C

Impedance with temperature can be neglected with film capacitors but is remarkable with ceramic capacitors.

With film technology there is no difference between stacked or wound versions.
