Micro-Fit TPA Connectors

Molex Micro-Fit Terminal Position Assurance (TPA) Connectors offer multiple circuit sizes and cable lengths for power applications. These Molex connectors offer 3mm pitch, up to 8.5A maximum current rating, and numerous design options, like terminal position assurance, blind-mating, and compliant pin features. Micro-Fit single- and dual-row connectors prevent terminal back-outs and are compatible with all existing Micro-Fit 3.0 receptacles, enabling a running change to incorporate the TPA products. Typical applications include consumer, telecommunication, medical, networking, sustainable energy, and automotive.
