KRG Series
The KRG series capacitors are designed for low profile applications. These miniaturized capacitors
have case sizes from 4 x 7mm to 18 x 25mm, enabling a large range of capacitance values while
maintaining a lower profile than standard general purpose capacitors. The KRG capacitors are also
ideal because they can be used over a wide temperature range,55Cto
105C.
The KRG series capacitors 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.
