High-power thick-film resistors
27 February 2019, Passive Components
Bourns announced the introduction of the new Model PWR221T-50 series high-power thick-film resistors.
This series is available in a compact TO-220 package utilising thick-film on ceramic technology, which provides the advantage of low inductance and the ability to absorb power up to 50 Watts when properly mounted to a heatsink.
The through-hole, radial leaded resistor is available with a wide resistance value range from 20 mΩ to 130 kΩ, and resistance tolerance options of 1% and 5%. These resistors are constructed with a thick-film resistive element on a white alumina ceramic substrate for contact with a heatsink which will be electrically isolated from the resistive element.
PWR221T-50 models are ideal for current limiting, current measurement and capacitor discharge applications. Industrial and telecom applications such as test and measuring equipment, motor drivers, rectifiers and power supplies are suitable for design-in. |
