APPLICATION INFORMATION
function of dissipated power at various lead lengths after mounting
TESTS AND REQUIREMENTES
Essentially all tests are carried out in accordance with
IEC 60115-1 specification, category LCT/UCT/56 (rated
temperature range: Lower category temperature, upper
category temperature; damp heat, long term, 56 days).
The tests are carried out in accordance with IEC 60068-2-xx
test
mechanical robustness testing procedure for electronic
components” and under standard atmospheric conditions
according to IEC 60068-1, 5.3.

In the Test Procedures and Requirements table the
tests and requirements are listed with reference to the
relevant clauses of IEC 60115-1 and IEC 60068-2-xx test
methods. A short description of the test procedure is also
given. In some instances deviations from the IEC
recommendations were necessary for our method of
specifying. For inflammability requirements reference is
made to IEC 60115-1.
All soldering tests are performed with mildly activated flux.
