Product Overview
The C2012X7R105KEP from TDK is a 1µF 25V MLCC in an 0805 (2012 metric) package with X7R dielectric and ±10% tolerance, featuring soft (flexible) termination. The EP suffix indicates TDK’s commercial-grade soft termination C series, which incorporates a conductive resin layer in the terminal electrodes to prevent ceramic cracking from PCB bending and thermal shock.
