New Power Resistor from Bourns

Bourns Announces New Power Resistor Product Designed To Meet High Temperature Soldering Requirements.

Bourns have announced that they have developed a new power resistor specifically engineered to meet high temperature soldering requirements that enable improved automated board assembly.  PWR263S-20, the new power resistor features a D²PAK surface mount package, which provides an optimal solution for space-constrained designs that have lead free soldering temperature requirements.  Bourns' new power resistor is ideal for high-volume; high power component automated assembly, and is a drop-in replacement for competitive thickfilm resistive products in D²PAK packages.  The new power resistor is designed to fit a broad range of applications that include industrial automation, telecommunication equipment, lighting controls, heating systems, battery chargers, inverter drives and general switch mode power supplies.

Bourns' PWR263S-20 power resistor features a low inductive resistive film which is ideal for high frequency circuits and provides high surge capability suitable for applications requiring resistors to discharge capacitive energy.  It also has a wide resistance range of 0.5 Ohms 1% and 5% to 130K Ohms 1% and 5% for increased stability and durability over a wide temperature range.
