Product details

1.00 mm Pitch, 8-Position SMD Header — Board Footprint and Current Budget

The BM08B-SRSS-TB(LF)(SN): The 1 A per-contact rating means the total harness current budget is 8 A; derate if the ambient exceeds 85°C. In a tight enclosure, that 4.9 mm is the z-height budget — factor in the cable bend radius below the header.

Solder Retention and Shrouding — What They Mean for Assembly

The header includes solder retention features — small tabs on the sides that anchor the part to the board during reflow. This prevents the header from floating or tombstoning as the solder paste reflows, and it adds shear strength once the cable is mated and tugged. In a production harness line, this reduces the reject rate from bent pins.

The insulation material is polyamide (nylon), natural colour.

Frequently asked questions

What is the mating connector for BM08B-SRSS-TB(LF)(SN)?

This header mates with the JST SH/SR series crimp receptacle housing. The mating half uses the same 1.00 mm pitch and 8-position layout. Confirm the specific receptacle part number against your wire gauge and seal requirements.

Is BM08B-SRSS-TB(LF)(SN) RoHS compliant?

Yes, the (LF)(SN) suffix indicates RoHS compliance and tin-plated contacts.
