BL 3 7 Z

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 3 7 Z is a 7-position female header connector designed for through-hole PCB mounting. It features a 2.54 mm (0.100 inch) pin spacing and utilizes tin-plated contacts with a CuSn-alloy base material. The component includes an internal spring contact type and offers a nickel plus gold surface finish on the contact sleeve, alongside a nickel plus tin finish on the contact surface. Rated for 3 A nominal current and 125 V AC, it withstands test voltages of 1500 V. The insulating body is constructed from PPS, supporting a temperature range of -40°C to +200°C, with soldering resistance up to 260°C for 10 seconds.
