1) This relay is highly sensitive polarized relay, if correct polarity is not applied to the coil terminals, the relay does not operate properly.

2) To avoid using relays under strong magnetic field which will change the parameters of relays such as pick-up voltage and drop-out voltage.

3) Relay is on the “reset” status when being released from stock, with the consideration of shock risen from transit and relay mounting, it should

be changed to the “set” status when application(connecting to the power supply). Please reset the relay to “set” or “reset” status on request.

4) Energizing coil with rated voltage is basic for normal operation of a relay, please make sure the energized voltage to relay coil have reached

the rated voltage. Regarding latching relay, in order to maintain the "set" or "reset" status, impulse width of the rated voltage applied to coil

should be more than 5 times of "set" or "reset" time.

5) For a monosteady state relay, after the relay is reliably operated, if it needs to be kept under pressure, make sure that the effective value of the

voltage is not less than 60% of the rated voltage;

6) The relay may be damaged because of falling or when shocking conditions exceed the requirement.

7) For SMT products, validation with real application should be done before your series production, if the reflow-soldering temperature curve is

out of our recommendation. Generally, two-time reflow-soldering is not recommended for the relay. However, if two-time reflow-soldering is

required, a 60-min. interval should be guaranteed and a validation should be done before production.

8) Please use wave soldering or manual soldering for straight-in relay. If you need reflow welding, please confirm the feasibility with us.

9) Contact is recommended for suitable condition and specifications if water cleaning or surface process is involved in assembling relays on PCB.

10) Regarding the plastic sealed relay, we should leave it cooling naturally untill below 40

oC after welding, then clean it and deal with coating,

remarkably the temperature of solvents should also be controlled below 40

oC.Please avoid cleaning the relay by ultrasonic, avoid using the

solvents like gasoline, Freon, and so on, which would affect the configuration of relay or influence the environment.

11) Relays packaged in moisture barrier bags meet MSL-3 requirements. The relays should be stored at ambient conditions of ≤30℃ and ≤60%

RH after they are removed from their packaging, and should be used within 168 hours. If the relays cannot be used within 168 hours, please

repack them or store them in a drying oven at 25℃±5℃, ≤10% RH. Otherwise, relays may be subjected to a soldering test to check their

performance, or they may be used after keeping them in an oven for 72 hours at with 50℃±5℃, ≤30% RH.

12) When applied with continuous current, the heat from relay coil will age its isolation. Thus, please do not ground connected the coil to reduce

electrical errosion if possible. And please provide protection circuit to avoid broken wire and losses.

13) Please make sure that there are no silicon-based substances (such as silicon rubber, silicone oil, silicon-based coating agents, silicon fillers,

etc.) around the relay, because it will generate silicon-containing volatile gas, which may cause poor contact in case of silicon-containing volatile

gas sticking on contact

14) About preferable condition of operation, storage and transportation, please refer to "Explanation to terminology and guidetines of relay".

15) During the relay pick-up or drop-out processes, there are stages of contact pressure change, contact vibration and unstable contact etc.

When the voltage applied to coil is gradually changed, it will lengthen the unstable stage and affect relay endurance. To reduce this influence,

please apply step voltage(switching circuit) to relay coil.
