Small Footprints! Johanson Dielectrics BME Mini-Switchmode® Capacitors

This new series of miniature switchmode power supply filter capacitors uses BME (Base Metal Electrode) construction to achieve 300-400% capacitance increases and component size reductions compared to their PME (Precious Metal Electrode) counterparts per the examples below.

BME Size / Capacitance Comparison
Technology Chips Volts Max. Cap.
PME 1x 1825 50V 1.2μF
BME 1x 1812 50V 4.7μF
PME 2x 2225 100V 4.4μF
BME 2x 2220 100V 22μF


  • High Capacitance, Small Size
