UT-A High-Temperature Power Resistors

Bourns UT-A High-Temperature Power Resistors are AEC-Q200-compliant wirewound resistors designed to deliver stable, accurate performance in demanding power applications subjected to extreme thermal stress. The Bourns UT-A series features a wide power range, resistance values from 10Ω to 4.5kΩ, and an operating temperature range of -55°C to +150°C. These performance features enable engineers to rely on a single qualified resistor family across powertrain, braking, and power conversion systems. These high-temperature power resistors feature a ceramic core and a flame-resistant silicone coating, providing tight tolerance options, a low temperature coefficient of resistance (TCR), and long-term reliability for high-reliability, safety-critical designs.
