B2B-EH-A(LF)(SN) Description

Short technical summary and product information.

The JST B2B-EH-A(LF)(SN) is a 2-position, single row, 2.50mm pitch male pin header from the EH series. It features a shrouded 3-wall design with a friction lock for secure mating, and is offered in a through-hole mounting configuration with press-fit or solder termination.

 

The header is rated for 3A current and 250V voltage, with an operating temperature range of -25°C to 85°C. Contacts are made of brass with a tin finish, and the insulator is polyamide (PA66/Nylon 6/6) rated UL94 V-0. Contact resistance is 20mΩ max (initial) and 30mΩ max after environmental tests; insulation resistance is 1000MΩ min; withstanding voltage is 1000V AC.

 

This connector is suitable for wire-to-board applications using AWG 28 to 22 wire, and is compatible with 1.6mm PC board thickness. The header is RoHS3 compliant and REACH unaffected.
