12V 30/40A 5-Pin SPDT Automotive Relay with Resistor Suppression | Replacement for Tyco VF4-15F11-S01

Heavy-duty 12V 30/40A 5-pin SPDT (1 Form C) automotive relay equipped with an integrated 680Ω parallel suppression resistor. Direct replacement for Tyco / TE Connectivity VF4-15F11-S01, V23136-A4-X58, and Western Star electrical systems.

The integrated suppression resistor safely clamps voltage spikes caused by inductive coil collapse, protecting sensitive vehicle electronics, body control modules (BCM), and engine ECUs from back-EMF damage without adding polarity sensitivity.
