Plot refers to incident continuous power of “P” Watts 2. Mounting surface is assumed an isotherm at T M °C 3. Actual testing done at P = 100 Watts, T M = 100 °C 4. Plot based on 1-dimensional heat transfer formula: T = T M + PR, where T = area-average resistive film temperature, held to 150 °C, max. R = thermal resistance, mounting surface to resistive film ≈ 0.5 °C/W for 30- and 20- dB devices (other values will run cooler and therefore handle more power – consult factory) Mounting Surface Temperature (°C) * Test Condition: With mounting surface temperature = 75 °C, max. (see plot above). Actual test conditions are as follows: Flange attached to a large copper carrier whose surface, directly under the flange center, is held at 100 °C; power applied = 100 Watts. Specification: The attenuation shall change no more that 0.2 dB during and after a 100-hr. Burn-in per MIL-PRF-55342. ** Attenuation vs. frequency as a function of temperature, -55°C to +125°C A M E R I C A N T E C H N I C A L C E R A M I C S www .atceramics.com ATC North America sales@atceramics.com ATC Asia sales@atceramics-asia.com ATC Europe saleseur@atceramics.com Sales of ATC products are subject to the terms and conditions contained in American Technical Ceramics Corp.
