Why JST

Volume Production Capacity

80M+ connectors per year across 3 production lines with automated stamping, injection molding, and assembly. Scale from prototype runs of 100 pcs to production orders of 5M+.

Fast Delivery

Standard XH, PH, VH, GH, and SH series maintained in stock. 90% of standard orders shipped within 3 business days.

Custom Connector Engineering

In-house tooling design for custom pin counts, wire gauges, and housing configurations. Typical lead time: 15-20 days for custom molds.

Quality Assurance

ISO 9001 and IATF 16949 certified. 100% automated electrical testing with insertion loss ≤ 0.3 dB and return loss ≥ 50 dB on all fiber-rated connectors.

Recent Project Examples

5G Base Station Backplane

A telecom equipment manufacturer required 24-pin GH series connectors with selective gold plating (0.5 μm) for high-frequency signal integrity on 5G macro base station backplanes. JST delivered 200,000 units over 6 months with insertion loss verified at ≤ 0.15 dB per contact at 6 GHz, passing Telcordia GR-1217 environmental qualification.

EV Battery Management System

An automotive Tier 1 supplier needed VH series high-current connectors rated for 8A continuous at +85°C ambient for battery cell monitoring harnesses. JST produced 500,000 custom harness assemblies with crimped VH contacts, each tested for pull force (≥ 19.6 N) and contact resistance (≤ 10 mΩ). The project ran for 14 months with zero field returns.

Industrial IoT Sensor Network

A factory automation integrator specified SH 1.0mm connectors for compact IoT sensor nodes deployed across 12 manufacturing plants. JST supplied 1.2 million SH connectors with reflow-compatible housings (260°C peak, 10 sec) and delivered on a Kanban replenishment schedule, maintaining 2-week safety stock for 18 months of continuous production.
