What are the key features of S3B-XH-A (LF)(SN)?
- 3-position single-row XH series layout at 2.5 mm pitch provides a compact wire-to-board interface for 3-wire harness connections on PCBs
- Right-angle through-hole design routes the mating connector along the PCB edge, enabling convenient cable access in compact enclosures
- Polarized housing prevents incorrect mating orientation, reducing mis-wiring risk and ensuring reliable harness connections in production
- Lead-free (LF) tin-plated (SN) contacts provide full RoHS compliance for consumer, hobby electronics, and industrial applications
What is S3B-XH-A (LF)(SN) used for?
The S3B-XH-A (LF)(SN) is widely used in consumer electronics, hobby robotics, and small appliances where a 3-wire harness must connect power, signal, or motor leads to a PCB at the board edge. Its 2.5 mm XH pitch and right-angle orientation make it ideal for Arduino-compatible boards, servo motor connectors, and compact enclosures requiring board-edge harness routing. The polarized housing ensures reliable repeated mating for field-replaceable wiring harnesses in maintenance-friendly product designs.

Frequently Asked Questions
What current rating and pin count does the JST S3B-XH-A (LF)(SN) support for wire harness connections?
The S3B-XH-A (LF)(SN) has 3 pins in a single-row right-angle XH configuration at 2.5 mm pitch, rated for up to 3 A per contact. Lead-free tin-plated contacts ensure RoHS compliance, making it suitable for consumer electronics, small motor control wiring, and 3-wire harness connections in compact appliance and hobby electronics designs.
Which small appliance and hobby electronics designs benefit most from the JST XH 2.5 mm pitch of the S3B-XH-A?
The 2.5 mm XH pitch of the S3B-XH-A is well established in servo motor wiring, battery harnesses, and small appliance power leads for hobby robotics and consumer electronics. Supporting up to 3 A per contact across 3 wires, it suits motors, fans, and LED assemblies, while the right-angle PCB mount keeps harness cables parallel to the board surface for tidy enclosure wiring.
How does the S3B-XH-A at 2.5 mm pitch compare to the JST PH 2.0 mm pitch connector for compact 3-wire harness applications?
The S3B-XH-A uses the JST XH 2.5 mm pitch, rated for up to 3 A per contact, while the smaller PH series at 2.0 mm pitch is rated for approximately 1 A per contact. The XH series is preferred for higher-current applications such as motor and power harnesses, whereas PH connectors are better suited for low-current signal connections in more space-constrained embedded designs.
