Product details

12-position dual-row 2.50mm pitch header with locking ramp

Right-angle through-hole with tin-plated contacts

The header is mounted through-hole, right-angle — the pins exit the bottom of the insulator at 90° to the mating face. The 0.134" (3.40mm) post length is long enough for a standard 1.6mm board with a good solder fillet on the bottom side.

Rated 3A per contact at 250V, UL94 V-0 housing

Each contact is rated 3A at 250V. The 3A figure is per circuit at the rated temperature — if you're running all 12 positions at current, the total heat is within the housing's thermal budget.

Frequently asked questions

What is the mating connector for S12B-XADSS-N(LF)(SN)?

This header mates with a JST XAD series receptacle housing that accepts crimp terminals. The locking ramp on the header engages with the receptacle's latch. Confirm the circuit count and pitch match your receptacle — the 12-position, 2.50mm pitch dual-row layout is standard for the XAD series.
