For a 1.25mm pitch system, expect a few amps per circuit with 28-30 AWG; the voltage ceiling is 50VAC/DC, which covers low-voltage signal and power distribution in consumer, industrial, and automotive auxiliary circuits. ## Temperature and Flammability – Where It Can Live The UL94 V-0 glass-filled nylon housing means the connector itself won't sustain a flame — a requirement for equipment that must pass a flammability test. ## Sourcing and Lifecycle – Active, Sourced per RFQ No end-of-life notice or successor has been published.","metaTitle":"Molex 205957-0471 Micro-Lock PLUS Header – 1.25mm","metaDescription":"Molex 205957-0471 Micro-Lock PLUS 1.25mm pitch, 4-position SMT header with latch holder.
