The KMG series capacitors are designed for general purpose use with an operating temperature range for most of these capacitors from 55؇C to 105؇C. The KMG series is a miniaturized version of the KME series with a load life of 1,000 hours at 105؇C with the rated ripple current applied. The KMG series capacitors below 350 volts were developed to withstand HCFC cleaning agents for five minutes by ultrasonic, vapor or immersion. This solvent proof design allows all circuit board components to be cleaned together, at the same time, without resorting to more expensive epoxy end-sealed capacitors. Refer to the Mini-Glossary for recommended cleaning conditions.
Ⅲ Radial lead terminals. Ⅲ Capacitance range: 0.1 to 22,000µF. Ⅲ Voltage range: 6.3 to 450VDC. Ⅲ Operating temperature range: 55؇C to 105؇C for 6.3 to 100V; 40؇C to 105؇C
for 160 to 400V; 25؇C to 105؇C for 450V. Leakage current: See specifications table for leakage current values at 20؇C. Ⅲ Ⅲ Standard capacitance tolerance: ؓ20%
