Detailed Specifications For Series KMG
• Miniature
• General Purpose
• Solvent Proof
• +105°C Maximum Temperature

The KMG series capacitors are designed for general purpose use with an operating temperature 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.
