8 / 10 page  CMA 0204 High Pulse Load MELF Resistor Vishay Beyschlag Document Number: 28717 For technical questions contact: ff3bresistors@vishay.com www.vishay.com Revision: 18-Jul-06 65 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.
