Measurement tool
50 Ω or 75 Ω
NM type connector
1. Characteristic impedance of all the
measuring devices (signal genera-
tor and cable) is 50Ω or 75Ω.
2. The PC board for the test is double
side copper clad phenolic paper
laminate with thickness of 1.6 mm.
3. Grounding terminal holes are plated
through.
4. Grounding terminal and one of the
coil terminals are soldered to the PC
board to be grounded.
5. Connection with measurement in-
strument is made with semi-rigid ca-
ble (Uniform Tube UT 141A) and
high frequency NM type connector.
NOTES
1. Soldering
Perform soldering under the condi-
tions below.
• Within 10s at 250°C 482°F
• Within 5s at 300°C 572°F
• Within 3s at 350°C 662°F
2. Counter voltage of DC relays
If input is cut off in DC relays, a
counter voltage is developed across
the coil as a result of the collapse of
the magnetic field. If the coil is used in
a transistor circuit, the reverse voltage
produced from the coil can cause a
serious circuit malfunction.

Expanslon of A
This counter voltage can be reduced
considerably by connecting a capaci-
tor or a diode in parallel with the coil.
The level of reduction must be deter-
mined either by calculation if the coil
data is available or by experiment.

3. Latching relay
In order to assure proper operating
regardless of changes in the ambient
usage temperature and usage conditions,
nominal operating voltage should be
applied to the coil for more than 40 ms to
set/reset the latching type relay.
For Cautions for Use, see Relay Technical Information (Page 48 to 76).
