Design Considerations For Power Resistors

Design considerations for power resistors include power rating, temperature coefficient, voltage rating, physical size, mounting requirements, resistance tolerance, inductance, noise, and surge current rating. The power rating should be selected to match the expected current and voltage ratings of the circuit, and the temperature coefficient should be selected to match the expected operating temperature range. The physical size should be selected to fit the available space and to allow for adequate cooling. Mounting requirements should be considered to ensure that the resistor is securely attached to the circuit board. The resistance tolerance should be chosen to ensure accuracy in the circuit. The inductance, noise, and surge current ratings should be selected to ensure the resistor can handle the expected load.
