What’s Next in the New World of Bourns? Application Note: Current Limiting Power Resistors for High Power LED Lighting Applications Temperature and thermal management is extremely important in providing a reliable LED design, especially in high power LED modules. The reliability of an LED module can be impaired dramatically by an increase in temperature, but due to its inherently low internal resistance, it is necessary to use external current limiting solutions. A new Bourns application note outlines the key factors that must be weighed when determining LED application operating current limitations and provides a single power resistor method that meets the thermal requirements in high power LED modules. Designers will learn about the advantages and simplicity of inserting a Bourns PWR263 high power resistor to limit current and dissipate power.
