Product details

What this 14-position MTA-100 header is for

Through-hole solder termination and a natural thermoplastic housing rated UL94 V-0 make it a standard fit for wave-solder assembly on single-sided or double-sided boards.

Temperature range and current rating

For a typical 22-24 AWG wire, expect 3-5 A per contact at 30°C rise. Voltage rating is 250 VAC, which is standard for signal-level and low-power distribution inside an enclosure.
