1. Quick Specifications
Rating classification: JST publishes connector ratings and test limits, not a separate “absolute maximum ratings” table. Treat the current, voltage, and temperature figures below as rated operating limits for the complete, properly terminated connector system—not semiconductor-style absolute maxima.
Distributor pages and older PH documents may show -25 °C to +85 °C for legacy ordering codes. Confirm the temperature requirement a...
