AEC-Q200 Certified Gadget in Compact SOT-227B Bundle Gives Excessive Pulse Dealing with Functionality and Energy Dissipation to 200 W
Vishay Intertechnology, Inc. launched a brand new AEC-Q200 certified thick movie energy resistor within the compact, low profile SOT-227B bundle for mounting on a heatsink. Out there with an non-compulsory NTC thermistor for inner temperature monitoring and pre-applied Part Change Thermal Interface Materials for extra environment friendly mounting, the Vishay MCB ISOA200 gives excessive pulse dealing with functionality and excessive energy dissipation as much as 200 W at an 80 °C backside case temperature.
Constructed on an uncovered alumina substrate as a substitute of a steel tab, the system launched, lowers prices and weight for automotive, industrial, and avionics, army, and area (AMS) functions, through which it would function a precharge, discharge, energetic discharge, or snubber resistor. For functions topic to excessive and repetitive pulse surges, the resistor can deal with excessive power pulses as much as 140 J for 0.1 s and is multi-pulsed examined. Extra customized testing choices for the system are additionally out there.
With the choice to combine an AEC-Q200 certified, temperature cycle examined NTC thermistor contained in the resistor bundle, the ISOA200 simplifies designs and saves board area, whereas its non-compulsory PC-TIM streamlines set up in manufacturing. The system’s excessive energy and excessive power dissipation additional simplify designs whereas decreasing prices by decreasing the necessity for energy elements.
The ISOA200 includes a resistance vary from 10 Ω to 1 MΩ, with tolerances of ± 5 % and ± 10 %, and TCR of ± 100 ppm/Ok and ± 150 ppm/Ok. The resistor gives a most working voltage of 1500 V, an working temperature vary of -55 °C to +150 °C, and dielectric power of 4000 Vrms. The RoHS-compliant system gives a non-inductive design and might embody two completely different resistors.
