Wire-to-board connectors target lithium battery applications
Crimp style connectors, which provide a space saving connection for wire-to-board connections that incorporate both power and signal circuits and sequencing for lithium batteries, have been introduced by JST. Measuring 3.0mm in height, the LBT A Type connectors incorporate polarisation and provide a stable contact performance under high vibration.
PCB mounted SMT headers are available in side entry configurations in 3, 5, 7 and 9 circuit sizes. The header power contacts are designed with a heat dissipation/heat sink feature, which radiates the heat away from the power contact permitting higher current carrying capability.
The connectors, which operate across a temperature range of -25 to +85°C, are rated at 7A AC/DC power and 0.5A AC/DC signal at 50V AC/DC. The PCB mounted power contacts are made of tin plated copper alloy, while the signal power contacts are made of phosphor bronze. Molded in a RoHS compliant 94V-0 material, the polarised housings feature a secure locking system. The SMT headers are provided on embossed tape for automatic insertion equipment.
