CP Series Relays Power Type

Panasonic's CP Series Relay (Power Type) is a compact, low-profile plastic sealed Automotive Relays with a small size form factor of 14.0mm length x 13.0mm width x 9.5mm height using PCB through-hole terminals. This relay is available in SPST (1FormA) and SPDT (1FormC) contact arrangements.

In addition, the CP Series Relay (Power Type) can maintain a 35A maximum continuous carry current for 1 hour or 45A carry current for up to 2 minutes (450mW type). This relay supports capacitor loads with 60A inrush current (1A steady state) for 100,000 cycles required for power supply applications.
