Song Chuan ISO 280 Micro Flux Tight Relays - 12V DC

ISO 280 Micro Relay with Resistor

ISO 280 Micro Relay with Resistor bottom bottom Micro Relay

Song Chuan's ISO 280 Micro Relays are a smaller version of a standard relay. As the name would suggest, this micro relay is meant to fit into Mini ATM fuse boxes and save space. These micro relays feature an ISO 280 footprint, pin size and arrangement. In addition, select micro relays feature a built-in resistor for easy use. The resistor in the micro relay protects equipment and applications against high voltage spikes. Available in 12 volt and 24 volt DC.
