Wire-to-Board Connectors for Lithium Battery Applications

The new LBT A Type Series crimp-style connectors recently introduced by JST Corp. provide a space-saving connection for wire-to-board connections that incorporate both power and signal circuits and sequencing for lithium battery and other power-connection applications. These SMT connectors have a low profile of 3.0 mm (0.118 in.) height when assembled. The LBT A Type Series offers compact size, incorporates polarization, and stable contact performance under high vibration, distortion, and unexpected external forces. The SMT headers are available in side-entry configuration. Their unique header power contact is designed with a “heat dissipation/heat sink” feature that radiates the heat away from the power contact, permitting higher current carrying capability.

Rated at 7A AC/DC (using 20 AWG) power and 0.5A AC/DC (using 28 AWG) signal at 50V AC/DC. PCB-mounted side-entry headers are available in 3, 5, 7, and 9 circuit sizes. The LBT A Type Series has an operating temperature of -25° C to +85° C, including temperature rise when applying an electrical current. The PCB-mounted power contacts are made of tin-plated copper alloy and the signal-power contacts are made of phosphor bronze. Molded in an RoHS-compliant 94V-0 material, the polarized housings feature a secure locking system. SMT headers are provided on embossed tape for automatic insertion equipment.
