- 1) Equivalent to the max. initial contact resistance is 100m (at 1A 6VDC). 

- 2) Test under the following conditions: 

- a.The relay is mounted on the PCB,the coil is applied with 100% rated votage; 

- b.The PCB board is a double layer board. The thickness of the copper foil is 4 oz (140µm),the width of each copper foil is 5.4x(1 5%)mm, the length of the copper foil is (50 1)mm,and the Tg value of the PCB board is 150 ; 

- c.The sample orders were only tested. 

- d.It varies by connection conditions. Additionally, reliable performance under repeated power-on cannot be guaranteed. Verify based on actual operating conditions during use. 

- 3) For NO contacts, at 23 , 13.5VDC, resistive load (100 cycles). 

- 4) For NO contacts, see "Load limit curve" for details. 

- 5) Lower limit target for on-off operation at low load. This value varies by on-off frequency, environmental conditions and expected reliability level; verify with actual load during use . 

- 6) 1min, leakage current less than 1mA. 

- 7) The value is measured when voltage drops suddenly from nominal voltage to 0 VDC and coil is not paralleled with suppression circuit. 

- 8) When energized, opening time of NO contacts shall not exceed 100µs, when non-energized, opening time of NC contacts shall not exceed 1ms, meantime, NO contacts shall not be closed. 

- 9) Since it is an environmental friendly product, please select lead-free solder when welding. The recommended soldering temperature and time is (260 3) , (5 0.5)s. 

- 10) Only for the 12VDC coil voltage type.

- 1)  The maximum allowable coil temperature is 180 . For 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. 

- 2)  If the actual operating coil voltage is out of the specified range, please contact Hongfa for further details.
