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 when assembled.
The LBT A Type Series offers compact size, incorporates polarization, and provides stable contact performance under high vibration, distortion, and unexpected external forces. The SMT headers are available in side-entry configuration. Their header power contact is designed with a heat dissipation/heat sink feature, which radiates the heat away from the power contact permitting higher current-carrying capability.
The connectors are rated at 7 A AC/DC (using 20 AWG) power and 0.5 A AC/DC (using 28 AWG) signal at 50 V 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 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 a RoHS compliant 94V-0 material, the polarized housings feature a secure locking system.
