Features
Metal Terminal Type For General Purpose
KRM Series
Bonding the metal terminals to external electrodes solves design issues
by mounting large size MLCC!
Bond metal terminals to the external electrodes of chips.
1
The stress applied to the chip is relieved by the elastic action of the metal terminal.
Substantially reduces noise, board deflection cracks and soldering cracks.
2
Board Deflection Cracks Solder CracksNoise
Lead-free High Temperature Solder
Reduces stress by the elastic action of the metal terminals!

Cracks from mechanical stress to boards and noise
from vibration of the capacitors are design issues.
This product is not damaged even with a board deflection of 6 mm.
Solder cracks do not occur even with 2,000 cycles of heat stress.
