Cautions

This section describes cautions designed to protect the performance of the thermal cutoff, Be sure to read and

fully understand these cautions.

To obtain full performance from the thermal cutoff, it is necessary for the customer to appropriately store

the thermal cutoff, design appropriate circuits for the application, and perform evaluations, mounting and

testing as necessary. Problems arising from the inappropriate execution of the above are the responsibility

of the customer, and NEC declines any and all responsibility.

Design Cautions

q Do not use this device for any purpose other than as a thermal cutoff.

The thermal cutoff is designed to detect abnormal rises in temperature and break circuits if needed. It is not

a current fuse that cuts excess current. If used as a current fuse, the SEFUSE may malfunction.

q Do not use this device in aerospace equipment, aeronautical equipment, nuclear reactor control systems, Iife

support equipment or systems, transportation machinery engine control or safety-related equipment.

This device is designed for use in household electric appliance, office automation equipment, audio and video

equipment, computer communications equipment, test and measurement equipment, personal electronic

equipment and transportation equipment (excluding engine control).

q The customer should select the proper thermal cutoff device, mounting location, and mounting method as

appropriate for each application.

Verify whether the chosen selections are appropriate by repeatedly testing the final design for thermal cutoff

under normal conditions as well as under predicted maximum abnormal conditions.

q Make designs so that the temperature of the body of the thermal cutoff does not exceed the temperatures

shown in Table 1.

If, the temperature is exceeded on a regular basis, the thermal cutoff may start operating only at temperatures

lower than the normal operating temperature. Malfunctions may also occur. Even if the thermal cutoff's

operating temperature is exceeded, it may malfunction.
