CIT offers automotive relays

CIT RELAY & SWITCH is offering A10 series relays for automotive applications. They are available in single-pole single-throw normally open (SPST N.O.) and single-pole double-throw (SPDT) contact configurations on both single and the dual styles, with contact ratings up to 30 A at 14 Vdc and PCB pin mounting available for both styles.

The A10 series relays feature operating temperatures up to 105 °C, <30 milli-Ohms contact resistance, 420 W maximum switching power, and 28 VDC maximum switching voltage. Maximum switching current is 40 A on and 30 A off with 3-second maximum current flow and a 1:10 make/break ratio. The relays are certified to QS9000 and ISO9002 standards, RoHS lead-free, with silver tin oxide (AgSnO 2) contacts and no cadmium.

Electrical life of A10 series relays is typically 100 K cycles, 20 A at 14 Vdc. Mechanical life is 10 M cycles and insulation resistance is 100 milli-Ohms at 500 Vdc. The A10 series measures 12.0 mm x 12.9 mm x 9.9 mm and weighs 4 g. The dual relay style measures 23.8 mm x 12.9 mm x 9.9 mm and weighs 8 g.
