High Pulse Load MELF Resistor
TESTS AND REQUIREMENTS
Essentially all tests are carried out in accordance with the
following specifications:
EN 60115-1, generic specification
EN 140400, sectional specification
EN 140401-803, detail specification
The Test Procedures and Requirements table contains the
applicable tests selected from the documents listed above.
The tests are carried out in accordance with IEC 60068 and
under standard atmospheric conditions in accordance with
IEC 60068-1, 5.3. Climatic category LCT/UCT/56 (rated
temperature range: Lower Category Temperature, Upper
Category Temperature; damp heat, long term, 56 days) is
valid.
Unless otherwise specified the following values apply:
Temperature: 15 ˚C to 35 ˚C
Relative humidity: 45 % to 75 %
Air pressure: 86 kPa to 106 kPa (860 mbar to 1060 mbar).
The components are mounted for testing on printed-circuit
boards in accordance with EN 140400, 2.3.3, unless
otherwise specified.
The requirements stated in the Test Procedures and
Requirements table are based on the required tests and
permitted limits of EN 140401-803.
