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 2.4V type relay

5. ORDERING INFORMATION

Notes 1).R type(Tape and reel) packing is moisture-proof which meets requirement of MSL-3. Please choose R type packing for SMT
             products. For R type, the letter “R” will only printed on packing tag but not on relay cover.
             Tube packing is normally not available for SMT products unless specially requested by customer.
             But, please note that tube packing is not moisture-proof so please bake the products before use according
             to description of Notice 10 herewith. In addition, tube packing 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 afer evaluation by HANDOUK.

5. OUTLINE DIMENSIONS, WIRING DIAGRAM AND PC BOARD LAYOUT                            Unit:mm

Remark
1).In case of no tolerance shown in outline dimension; outline dimension1mm,tolerance should be ±0.2mm;
 
outline dimension>1mm and   5mm,tolerance should be ±0.3mm; outline dimension >5mm, tolerance should be ±0.4mm.
2).The tolerance without indicating for PCB layout is always
±0.1mm.
3) The width of the gridding is 2.54mm.

6. TAPE PACKING

Remark

1).In case of no tolerance shown in outline dimension; outline dimension1mm,tolerance should be ±0.2mm;

  outline dimension>1mm and   5mm,tolerance should be ±0.3mm; outline dimension >5mm, tolerance should be ±0.4mm.

2).The tolerance without indicating for PCB layout is always ±0.1mm.
3) The width of the gridding is 2.54mm.

7. CHARACTERISTIC CURVE

Notice

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

6)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.

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

8)Regarding the plastic sealed relay, we should leave it cooling naturally until below 40 after welding, then clean it and deal with coating, remarkably the temperature of solvents should also be controlled below 40. Please avoid dealing the relay by ultrasonic, avoid using the solvent like gasoline, Freon, and so on, which would affect the configuration of relay or influence the environment.

9)About preferable condition of operation, storage and transportation, please refer to “Explanation to terminology and guide tines of relay”

10)Relays packaged in moisture barrier bags meet MSL-3 requirements. The relay should be stored at ambient condition of under 30 and under 60% RH after the relay 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, under 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, under 30%RH.

Disclaimer

The specification is for reference only. See to “Terminology and guidelines” for more information. Specifications subject to change without notice. We could not evaluate all the performance and all the parameters for every possible application. Thus the user should be in a right position to choose the suitable product for their own application. If there is any query, please contact HANDOUK for the technical service. However, it is the user’s responsibility to determine which product should be used only.
