Vishay Intertechnology has introduced a new thick film power resistor MCB ISOA200 that is AEC-Q200 rated and comes in the compact, low profile SOT-227B package for heatsink mounting.
The Vishay MCB ISOA200, which comes with an optional NTC thermistor for internal temperature monitoring and pre-applied Phase Change Thermal Interface Material (PC-TIM) for more efficient mounting, has a high pulse handling capability and can dissipate up to 200 W at an 80 °C bottom case temperature.
Built on an Exposed Alumina Substrate Instead of a Metal Tab, The New Device Features:
- Lowers costs and weight for automotive, industrial, and avionics, military, and space (AMS) applications, in which it will serve as a precharge, discharge, active discharge, or snubber resistor.
- For applications subject to high and repetitive pulse surges, the resistor can handle high energy pulses up to 140 J for 0.1 s and is multi-pulsed tested.
- Additional custom testing options for the device are also available.
- Option to integrate an AEC-Q200 qualified,
- Temperature cycle tested NTC thermistor inside the resistor package,
- The ISOA200 simplifies designs and saves board space, while its optional PC-TIM streamlines installation in production.
- The device’s high power and high energy dissipation further simplify designs while lowering costs by reducing the need for power components.
The ISOA200 Features:
- A resistance range from 10 ? to 1 M?, with tolerances of ± 5 % and ± 10 %, and TCR of ± 100 ppm/K and ± 150 ppm/K.
- The resistor offers a maximum operating voltage of 1500 V, an operating temperature range of -55 °C to +150 °C, and dielectric strength of 4000 Vrms.
- The RoHS-compliant device offers a non-inductive design and can include two different resistors.
Availability
Samples and production quantities of the new resistor are available now, with lead times of 12 weeks.
