BM25-4S/2-V(53) Description

Short technical summary and product information.

The BM25-4S/2-V(53) from Hirose Electric is a small hybrid board-to-FPC connector designed for high-current applications in mobile devices. It features a socket with center strip contacts, providing 6 positions total: 4 signal contacts rated at 1A each and 2 power contacts rated at 9A each. The connector has a 0.7mm stacking height and a depth of 2.6mm, enabling low-profile designs.

 

The connector is surface mountable with solder retention features for reliable attachment. The gold-plated copper alloy contacts ensure low contact resistance: 5mΩ for power contacts and 30mΩ for signal contacts. The housing is made of LCP with UL94V-0 flammability rating, suitable for space-constrained environments.

 

With a rated voltage of 30V AC/DC and an operating temperature range of -40°C to +85°C, this connector is ideal for battery connections and USB connections in portable electronics. The design includes multipoint clipping contacts for high reliability and a metal guide structure for robust mating.

 

The BM25 series is RoHS compliant and halogen-free, meeting environmental standards. The connector is available in tape and reel packaging for automated assembly.
