SL 1 128 21 Z

Headers, Male Pins Overview

The SL 1 128 21 Z is a single-row pin header connector manufactured by Fischer Elektronik. It features 21 contacts with a 0.100 inch (2.54 mm) pitch, designed for through-hole mounting on printed circuit boards. The contacts are constructed from bronze alloy and finished with tin plating to ensure reliable electrical conductivity. This component supports a maximum current of 3 A and withstands voltages up to 250 V AC, with an insulation resistance exceeding 107 Ω·m. The housing utilizes PA 4.6 material rated UL 94 V-0 for flammability.
