Aliso Viejo, California - Need to switch 3-amps? Only have .22" square inch for the relay? Look for American Zettler's new AZ939 Series. Combining an extremely small PCB footprint with a sensitive coil, the AZ939 solves the expensive PCB "real estate" problem and reduces power consumption compared to other popular 3-amp relays. The small size is no obstacle for high isolation either-the AZ939 can withstand 4kVrms!
