KMR Aluminum Electrolytic Capacitors Chemi-Con KMR Aluminum Electrolytic Capacitors are a downsized version of the KMQ and KMH series, measuring 5mm less in height than the current snap-in KMQ series. Chemi-Con KMR Aluminum Electrolytic Capacitors offer a 100µF to 3300µF capacitance range, rated voltage range from 160 to 450VDC, operating temperature range from -25°C to 105°C, and RoHS compliance. The non-solvent-resistant KMR Series was designed for inverter control and switching power supply applications.
