Description
• Power Windows
• Fuel Pumps
• Fans
The ISO Micro Relays Series includes a range of general-
purpose automotive plug-in relays for controlling lamps,
horns, power windows, fuel pumps, lift gates, and more.
These ISO Micro relays are smaller than standard-size Mini
plug-in relays for space savings in hard-wired boxes.
This series offers a variety of models, including a 16 V Max
SPST 4-pin Mini-Micro relay, a 16 V Max SPDT 5-pin Micro
relay, and several 30 V Max Form A and Form C Micro
relays. Some models feature resistor suppression, while
others have no suppression.
Features and Benefits
• Form A single-pole, single-throw (SPST) and Form C
single-pole, double-throw (SPDT) relays
• 14 V and 15.6 V coil versions are available
• All models feature an isolated coil
• Dielectric strength of 500 V
