• Manufacturer Part Number: 122C
• Description: Centrigrid Magnetic Latching Aerospace Relay
• Manufacturer: Willow Technologies Ltd

SERIES 122C
10.
SPACER PAD
Relays can be supplied with a spacer pad attached to the relay header. The pad permits the
relay to be spaced away from the mounting surface facilitating solder joint inspection. To order
add M9 to the part number. Example: 122CM9-26.
NOTES:
1. Material: Polyester film.
2. Add 0.01 ohm to contact resistance with mounting pad.
NOTES:
1 . “Typical” characteristics are based on available data and are best estimates. No on-going verification tests are performed.
2. Relay contacts will exhibit no chatter in excess of 10 µsec or transfer in excess of 1 µsec.
3. Screened HI-REL versions available. Contact factory.
4. Pins 4, 5 and 9 must be shorted when tested for Insulation Resistance and Dielectric Withstanding Voltage.
5. Unless otherwise specified, relays will be supplied with either gold plated or solder coated leads.
6. Unless otherwise specified, parameters are initial values.
7. The slash and characters appearing after the slash are not marked on the relay.
8. Maximum rated gate voltage = 15 VDC.
9. Measured for 5 sec max. Includes allowance for “on” resistance of MOSFET.
