2) Test under the following conditions:
a. The relay is mounted on the PCB, the coil is applied with 100% rated
voltage;

Initial insulation resistance
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.
between contacts: 500VAC
between coil & contacts: 500VAC
Typ.: 2.5ms (at nomi. vol.)
Max.: 10ms (at nomi. vol.)
3) See "Load limit curve" for details.
Dielectric strength 4)
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 10µs,
When energized, opening time of closed NO contacts shall not exceed
10µs.
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.
