Construction

Load type

2)

2) Test under the following conditions:

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

voltage;

b. The PCB board is a double layer board. The thickness of the copper

foil is 4 oz (140

µm),the width of each copper foil is 3.76×(1±5%)mm,

the length of the copper foil is 50 mm

±1 mm, and the Tg value of

the PCB board is 150

°C.

c. Not suitable for double relay adding load simultaneously.

3) See "Load limit curve" for details.

4) 1min, leakage current less than 1mA.

5) The value is measured when voltage drops suddenly from nominal

voltage to 0 VDC and coil is not paralleled with suppression circuit.

6) When non-energized,close time of NO contacts shall not exceed 10

µs,

When energized, opening time of closed NO contacts shall not exceed

10

µs.

7) Since it is an environmental friendly product, please select lead-free

solder when welding. The recommended soldering temperature and

time is (260 3)

, (5 0.3)s.

1)Initial value,Equivalent to the max. initial contact resistance is 100m

(at 1A 6VDC).
