NOTES

1. Coil operating power

Pure DC current should be applied to the

coil.The wave form should be rectangular.

If it includes ripple, the ripple factor should

be less than 5%.

However, check it with the actual circuit

since the characteristics may be slightly

different.

2. Cleaning

For automatic cleaning, the boiling meth-

od is recommended. Avoid ultrasonic

cleaning which subjects the relays to high

frequency vibrations, which may cause

the contacts to stick.

It is recommended that alcoholic solvents

be used.

3. Soldering

1) The soldering shall be performed under

following condition.

The affect of the PCB on the relay will dif-

fer depending on the type of PCB used.

Please verify the type of PCB to be used.

Soldering time: within 5s

2) In case of automatic soldering, the fol-

lowing conditions should be observed

(Surface-mount terminal)

(1) Position of measuring temperature

(2) IR (infrared reflow) soldering method

Temperature rise of relay itself may vary

according to the mounting level or the

heating method of reflow equipment.

Therefore, please set the temperature of

soldering portion of relay terminal and the

top surface of the relay case not to exceed

the above mentioned soldering condition.

It is recommended to check the tempera-

ture rise of each portion under actual

mounting condition before use.

4. Packing style

1) Tape dimensions

2) Dimensions of plastic reel

5. Conditions for operation, transport

and storage

1) Ambient temperature, humidity, and at-

mospheric pressure during usage, trans-

port, and storage of the relay:

(1) Temperature:

(2) Humidity: 5 to 85% RH

(Avoid freezing and condensation.)

The humidity range varies with the tem-

perature. Use within the range indicated

in the graph below.

(3) Atmospheric pressure: 86 to 106 kPa

Temperature and humidity range for us-

age, transport, and storage:

2) Condensation

Condensation forms when there is a sud-

den change in temperature under high

temperature and high humidity conditions.

Condensation will cause deterioration of

the relay insulation.

3) Freezing

Condensation or other moisture may

freeze on the relay when the temperature

lems such as sticking of movable parts or

operational time lags.

4) Low temperature, low humidity environ-

ments

The plastic becomes brittle if the relay is

exposed to a low temperature, low humid-

ity environment for long periods of time.
