Product Description

The 7442 8W resistor is a high-performance wirewound resistor designed for applications requiring high power dissipation and reliability. Featuring an 8W power rating, the 7442 8W wirewound resistor is constructed with a durable ceramic core and alloy resistance wire, ensuring stability under high-temperature conditions. It operates within a voltage range of up to 500V DC/AC and can withstand ambient temperatures from -55°C to +275°C. Commonly used in industrial power supplies, motor controls, and automotive systems, the 7442 high power resistor offers excellent thermal management and low inductance. Its robust design supports direct integration into circuit boards or heat sinks. While it delivers high precision (±5% tolerance) and durability, its larger physical size may require additional mounting space. No external communication interfaces or battery/screen components are included in this passive component.
