B04B-PASK-1(LF)(SN) Description

Short technical summary and product information.

The JST B04B-PASK-1(LF)(SN) is a 4-position, single-row, 2.00mm pitch through-hole header from the PA family. It features a shrouded 4-wall design with a locking ramp for secure mating with PA series crimp housings. The header uses kinked pin solder terminals and is made with copper alloy contacts finished in tin.\n\nElectrical ratings include 3A current and 250V voltage, with an operating temperature range of -25°C to 85°C. The insulation is natural polybutylene terephthalate (PBT) glass-filled with a UL94 V-0 flammability rating. A board guide feature assists alignment during assembly.\n\nThis connector is suitable for board-to-cable/wire applications requiring a compact, reliable connection. The through-hole mounting and locking ramp provide mechanical stability in high-vibration environments.
