The JST SM04B-HCHK-TB(LF)(SN) is a male HCH automotive connector, engineered for through-hole mounting on PCBs in automotive electrical systems. This connector supports four solder terminations, making it ideal for compact and low-profile wire-to-board connections commonly required in vehicles and related equipment.
Its design incorporates a reinforcing tab to ensure a secure connection, especially in high-vibration environments typical of automotive applications. The 2.54 mm pitch header is devised for mating with JST HCH series female housings, providing flexible system integration. Black glass-filled liquid crystal polymer is used for the housing material, providing enhanced mechanical strength and resistance to heat.
The connector utilizes brass contacts plated with nickel over tin for reliable conductivity and corrosion resistance. With a maximum current rating of 5A and operation at temperatures from -40°C to 120°C, this connector is suitable for demanding conditions.
It offers a compact footprint with dimensions of 10.9 mm height, 21.8 mm depth, and 19.6 mm width. Through-hole mounting and solder termination simplify installation in production environments.
With RoHS compliance, this connector meets current electronic safety and environmental standards. The HCH series is widely used in automobile wire harnesses, control units, and other systems requiring rugged and reliable electrical connectors.
Common applications include automotive PCB wire connections, instrumentation panels, electronic control modules, and other automotive electrical equipment. The miniaturised design caters to modern, space-constrained electronics in vehicles.
