Vishay Intertechnology Thick Film Power Resistor With Optional NTC Thermistor and PC-TIM Simplifies Designs, Saves Board Space, and Lowers Costs
May 30 2023 - 11:00AM
Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new
AEC-Q200 qualified thick film power resistor in the compact, low
profile SOT-227 package for mounting on a heatsink. Available with
an optional NTC thermistor for internal temperature monitoring and
pre-applied Phase Change Thermal Interface Material (PC-TIM) for
more efficient mounting, the Vishay MCB ISOA offers high pulse
handling capability and high power dissipation up to 120 W at an 85
°C bottom case temperature.
Built on an exposed alumina substrate instead of a metal tab,
the device released today lowers costs for automotive, industrial,
and avionics, military, and space (AMS) applications, in which it
will serve as a precharge, discharge, active discharge, or snubber
resistor. With the option to integrate an AEC-Q200 qualified,
temperature cycle tested NTC thermistor inside the resistor
package, the ISOA simplifies designs and saves board space, while
its optional PC-TIM streamlines installation in production.
The device’s high power and high energy dissipation simplifies
designs and lowers costs by reducing the need for power components.
For applications subject to high and repetitive pulse surges, the
resistor can handle high energy pulses (i.e., 110 J for 0.1 s) and
is multi-pulsed tested at 230 J for 670 ms and 3000 cycles and 350
J for 1060 ms and 5000 cycles. Additional custom testing options
for the device are also available.
The ISOA features a resistance range from 0.47 Ω to 1 MΩ, with
tolerances of ± 5 % and ± 10 %, and TCR of ± 100 ppm/K, ± 150
ppm/K, and ± 300 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.
Samples and production quantities of the new resistor are
available now, with lead times of 15 weeks.
