Bourns UALH series aluminum housed high power wirewound resistors

The Bourns® UALH series aluminum-housed high-power wirewound resistors are fixed resistors engineered for stability and reliability under demanding electrical and thermal conditions. Advanced wirewound construction is protected by a silicone molding compound and enclosed in an aluminum shell to optimize heat dissipation. The series offers a resistance range of 0.5Ω to 22kΩ, with ±5 % tolerance, and operates from -55°C to +275°C.

Features

• Power rating of 100 W with heat sink
• Resistance of 0.5 Ω to 22 kΩ
• Operating temperature range: -55 °C to +275 °C
• RoHS compliant* and halogen free**

Applications

• Industrial motor controls
• Industrial power supplies
• High power machinery
