THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 FUNCTIONAL PERFORMANCE 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. TESTS AND REQUIREMENTS All tests are carried out in accordance with the following test procedures and specifications: IEC 60115-1 ICE 60068-1 IEC 61340-3-1 MIL-STD-202 The tests are carried out under standard atmospheric conditions in accordance with IEC 60068-1, 5.3.
