Current Rating Factor vs. Ambient Temperature _amb
Note
• The current rating factor depends on the mounting and environmental conditions. The power dissipation on the thermal fuse generates a
temperature rise against the local ambient, depending on the heat flow supported by additional conductive materials as electrical wires, lead
frames or other electrical connections (thermal resistance). Please contact the factory (please refer to e-mail contact below) for support and
further technical details.
