AUTOMOTIVE RELAY Features 40A switching capability 1 From A &1 Form C contact arrangement Plastic sealed and dust protected types available ROHS & ELV compliant Typical Applications Fog lamp&headlight control,Rear window defogger, Air-conditioning,Fuel pump cintrol,Cooling fan control, Battery disconnection device CHARACTERISTICS Contact arrangement Plastic sealed, Dust protected Voltage drop(initial) Unit weight Max.switching voltage See “ Load limit curve” Min.contact load Electrical endurance Mechanical endurance Initial insulation resistance Dielectric strength 3) Operate time 10) Notes: 1) For NO contacts,measured when applying 100% rated votage on coil. For NC contacts,measured when applying zero votage on coil. 2) Inrush peak current under lamp load,at 13.5VDC. 3) 1min.leakage current less than 1 mA. 4) The value is measured when voltage drops suddenly from nominal voltage to 0VDC and coil is not parallelewith suppression circuit. 5) When energized,opening time of NO contacts shall not exceed 1ms,when non-energized,opening time of NC contacts shall not exceed 1ms,meantime,NO contacts shall not be closed. 6) FMVSS 302:Federal Motor Vehicle Safety Standard. 7) Do NOT knock on relays with hard objects such an rubber rod and rubber hammer during mounting,which might lead to relay damage. 8) Only valid for QC version. 9) Test point is at 2mm away from teminal end,and after removing testing force,the terminal transfiguration shall not exceed 0.5mm. 10) Only for the 12VDC coil voltage type. Release time Ambient tenperature Shock resistance 5)10) Flammability CONTACT DATA Load current A Load voltage Load type Load wiring diagram 4) Contact material Make Break JINTIAN RELAY ISO9001、ISO14001、OHSAS18001 CERTIFIED JINTIAN RELAY Ambient temp.

Notes: 1) The load in the table excludes flasher.When applied in flasher,a special silver alloy(AgSnO 2)contact material should be used used and the customer special code should be (170)as a suffix.Please heed the anode and cathode’s request when wired, terminal 30 should connect with anode. 2) Corresponds to the peak inrush current on intial actuation (cold filament). 3) A low resistive or diode suppression device in parallel to the relay coil increases the release time and reduces the life time caused by increased erosion and/or higher risk of contact welding. 4) The load wiring diagrams are...

CHARACTERISTIC CURVES 1.Coil operaying voltage range Ambient temperature (°C) 1) There should be no contact load applied when maximum continuous operation voltage is applied on coil. 2) This chart takes dust protected,12VDC coil voltage version as example. 3) The maximum allowable coil temperature is 180℃. Considering the coil temperature rise which is measured by resistance is average value,we recommend the coil temperature should be below 170℃ under the different application ambient, different coil voltage and different load etc. 4) If the actual operating coil voltage is out of the specified...
