A new AEC-Q200-compliant, high power thick film resistor series has been announced by supplier of electronic components, Bourns. The Bourns Model PWR247T-100 series is offered in a compact TO-247 package. The product is engineered with a thick film resistive element on a white alumina ceramic substrate, the latest high power resistors from Bourns deliver low inductance advantages.

This element enables heat sink contact that is electrically isolated from the resistive element making the device able to absorb power up to 100W when properly mounted to a heat sink.

The radial-leaded Model PWR247T-100 features a through-hole mount, and provides a wide resistance value range from 50mΩ to 1MΩ. The series also has a high power rating and is compatible with typical lead-free solder reflow temperatures.

The new resistors are available in one percent and five percent tolerance options. These features and benefits make Bourns' new high power thick film resistors suitable for handling current limiting, current measurement and capacitor discharge functions required in a variety of industrial and telecom applications such as test and measurement equipment, motor drivers, rectifiers and power supplies.

The PWR247T-100 series is available now, and is RoHS compliant and halogen free.
