Notes: 1) When user's requirements can't be found in the above table,special order allowed.
2) In case 5V of transistor drive circuit, it is recommended to use 4.5V type relay, and 3V to use 2.4V type relay.

Special code2) XXX: Customer special requirement Nil: Standard
Notes: 1) For the R type, the letter "R" will only be printed on packing tag and will not appear on relay cover. In addition, tube packaging will be adopted when the ordering quantity of R type is equal to or less than 100 pieces unless otherwise specified.
2) The customer special requirement express as special code after evaluating by Hongfa.
Resistive load, at 4oC, 1s on9s off.
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 2 coil latching relay, do not energize voltage to "set" coil and "reset" coil simultaneously.
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 forthe 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) Contact is recommended for suitable condition and specifications if water cleaning or surface process is involved in assembling relays on PCB.
9) Regarding the plastic sealed relay, we should leave it cooling naturally untill below4oC after welding, then clean it and deal with coating, remarkably the temperature of solvents should also be controlled below 4oC.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.
10) About preferable condition of operation, storage and transportation, please refer to "Explanation to terminology and guidetines of relay".
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°C±5'C, <100% 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°C±5°C,30%o RH.
