Vishay Intertechnology Launches Innovative Thick Film Power Resistor
Vishay Intertechnology, Inc. has recently announced an exciting addition to its product line: a new AEC-Q200 qualified thick film power resistor. This resistor comes in a compact and low profile SOT-227B package, specifically tailored for efficient mounting on heatsinks. A standout feature of the Vishay MCB ISOA200 is its optional NTC thermistor, which offers internal temperature monitoring, along with pre-applied Phase Change Thermal Interface Material (PC-TIM) for enhanced installation efficiency.
Key Features of the ISOA200 Resistor
One of the key advantages of the ISOA200 is its remarkable high pulse handling capability, allowing for high power dissipation of up to 200 W while maintaining a bottom case temperature of 80 °C. Built upon an exposed alumina substrate rather than a metal tab, this innovative design reduces both costs and weight, making it an ideal choice for various applications, including automotive, industrial, avionics, military, and space (AMS) sectors.
This resistor is capable of accommodating high energy pulse surges up to 140 J for 0.1 seconds and is subjected to multi-pulse testing, ensuring its performance under demanding conditions. Moreover, the availability of custom testing options enhances its adaptability for specific customer requirements.
Streamlined Design and Space Saving
The integration of a temperature cycle tested NTC thermistor is another significant feature that simplifies design processes and conserves valuable board space. This capability streamlines production by minimizing component count, making the ISOA200 a forward-thinking solution for engineers and designers. With high power ratings and energy dissipation capabilities, it effectively reduces the need for additional power components, ultimately leading to cost reductions and more compact designs.
Technical Specifications and Availability
The ISOA200 offers a versatile resistance range from 10 ? to 1 M?, accommodating tolerances of ± 5% and ± 10%. It features temperature coefficient ratings (TCR) of ± 100 ppm/K and ± 150 ppm/K. This robust resistor can operate at a maximum voltage of 1500 V in a temperature range from -55 °C to +150 °C, with a dielectric strength of 4000 Vrms. Additionally, the device is RoHS-compliant and incorporates a non-inductive design, allowing for the inclusion of two different resistors.
Vishay is currently offering samples and production quantities of the ISOA200 resistor, with lead times of approximately 12 weeks. This fast availability underscores Vishay's commitment to addressing the needs of its customers across diverse industries.
