CAUTION

ELECTROSTATIC DISCHARGE DAMAGE

This component is sensitive to electrostatic discharge (ESD). Take normal ESD precautions in handling this product to prevent ESD induced damage and/or degradation.

Failure to comply with these instructions may result in product damage. SOLDERING/ASSEMBLY

CAUTION

IMPROPER SOLDERING

case. Ensure leads are adequately supported during any forming/ shearing operation so that they are not stressed inside the plastic Limit exposure to high temperatures. Do not wave solder the SS345PT.

Failure to comply with these instructions may result in product damage.

Note 1:

Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device. However, the electrical and mechanical characteristics are not guaranteed as the maximum limits (above recommended operating conditions) are approached, nor will the device necessarily operate at absolute maximum ratings.

NOTICE

The magnetic field strength (Gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic characteristics. To test the switch against the specified magnetic characteristics, the switch must be placed in a uniform magnetic field.
