Product details

20-Pin Dual-Row Power Header for Wire-to-Board Harnesses

The Molex 430452027 is a 20-circuit, dual-row header from the Micro-Fit 3.0 43045 series. The 3.00 mm pitch and 0.125" (3.18 mm) solder-tail length suit standard through-hole PCB layouts. The housing is black UL94 V-0 LCP, rated from -40°C to 105°C, and the contacts are tin-plated (60.0 µin / 1.52 µm on the mating surface).

Locking Ramp and Full Shroud for Vibration Resistance

A built-in board guide aids alignment during automated assembly.

This header is specified for automotive, general-purpose industrial, medical, and telecommunications equipment. The UL94 V-0 rating satisfies flame-retardant requirements for equipment inside enclosures.
