Precautions
Handling
To preserve performance, do not drop or otherwise subject the
Power Relay to shock.
The case is not designed to be removed during normal handling
and operation. Doing so may affect performance.
Use the Power Relay in a dry environment free from excessive
dust, SO2, H
2
S or organic gas.
Do not allow a voltage greater than the maximum allowable coil
voltage to be applied continuously.
Do not use the Power Relay outside of specified voltages and
currents.
Do not allow the ambient operating temperature to exceed the
specified limit.
Installation
Although there are not specific limits on the installation site, it
should be as dry and dust-free as possible.
PCB Terminal-equipped Relays weigh approximately 100g. Be
sure that the PCB is strong enough to support them. We
recommend dual-side through-hole PCBs to reduce solder
cracking from heat stress.
Cleaning PCB Terminals
PCB terminals have flux-tight construction which prevents flux from
penetrating into the relay base housing e.g. due to capillary action
up the terminals when the relay is soldered onto the PC board. This
type of relay cannot be immersed for cleaning.
Operating Coil
As a rule, either a DC battery or a DC power supply with a
maximum of 5% ripple is used for the operating voltage for DC
relays. Before using a rectified AC supply, confirm that the ripple
is not greater than 5%. Ripple greater than this can lead to
variations in the operating and reset voltages.
An excessive ripple can generate pulses, the insertion of a
smoothing capacitor is recommended as shown below.

When driving a transistor, check the leakage current and
connect a bleeder resistor if necessary.
