Wire-wound resistor UT series

powerceramic-housedfor electronics

Bourns® UT-A Series high-temperature power resistors are AEC-Q200 compliant wirewound components designed to deliver stable, accurate performance in demanding power applications exposed to extreme thermal stress. With a wide power range, resistance values from 10 Ω to 4.5 kΩ, and an operating temperature range of −55 °C to +150 °C, the UT-A Series enables engineers to standardize on a single qualified resistor family across powertrain, braking, and power conversion systems. Built with a ceramic core and flame-resistant silicone coating, these resistors provide long-term reliability, tight tolerance options, and low TCR to support high-reliability, safety-critical designs. Features Resistances from 10 Ω to 4.5K Ω Resistance tolerances as low as ±1 % Power rating: 1 to 10 watts Excellent pulse handling Low TCR: ±30 PPM/°C standard Silicone coated power resistor AEC-Q200 compliant RoHS compliant* Applications Energy and storage Industrial power supplies Inverters and motor drives Capacitor recharge and discharge Voltage regulators Telecommunications Sustainability High pallet density for lower C02 Eco-logistics-friendly packing Recyclable ESD-safe packaging Corrosion-resistant for longevity
