Automotive Relays TB RELAYS

GUIDELINES FOR USAGE

Standard type

High heat resistant type

Usage, transport and storage conditions

1) Ambient temperature, humidity and air pressure during

usage transport, and storage of the relay:

(1) Temperature: –40 to +85°C (Standard type)

–40 to +110°C

(High heat-resistant type/Pin in Paste compliant type)

(2) Humidity: 2 to 85% RH (Avoid icing and condensation)

(3) Air pressure: 86 to 106 kPa

The humidity range varies with the temperature. Use within the

range indicated in the graph below.

[Temperature and humidity range for usage, transport, and

storage]

For general cautions for use, please refer to the "Automotive Relay Users Guide".

2) Water condensation

Water condensation occurs when the ambient temperature

drops suddenly from a high temperature and humidity, or, the

relay is suddenly transferred from a low ambient temperature

to a high temperature and humidity. Condensation causes

the failures like insulation deterioration, wire disconnection

and rust etc. Panasonic Corporation does not guarantee the

failures caused by condensation. The heat conduction by the

equipment may accelerate the cooling of relay itself, and the

condensation may occur. Please confirm no condensation

in the worst condition of the actual usage. (Special attention

should be paid when high temperature heating parts are close

to the relay. Also, please consider the condensation may occur

inside of the relay.)

3) Icing

Please check the icing when an ambient temperature is

lower than 0°C. Icing means, the moisture contained in the

surrounding environment and inside the relay freezes when the

ambient temperature falls below the freezing point. The icing

causes the sticking of movable portion, the operation delay

and the contact conduction failure etc. Panasonic Corporation

does not guarantee the failures caused by the icing. The heat

conduction by the equipment may accelerate the cooling of

relay itself and the icing may occur. Icing condition is changed

by ambient environment, please make sure to confirm no icing

in the worst condition of the actual usage.
