Compliance: This product complies with RoHS, REACH, and lead-free requirements, meeting global environmental standards for electronics manufacturing.
The metal foil element is mounted on a ceramic substrate, providing excellent thermal conductivity and mechanical stability. This design ensures efficient heat dissipation, maintaining performance even under high power conditions. The 3W power rating is impressive for a component of this size, allowing designers to maximize power handling without increasing board space.
The resistor's low inductance (typically less than 10 nH) makes it suitable for high-frequency applications, where inductive effects could otherwise compromise circuit performance. Its low TCR ensures stable performance across a wide temperature range, from -55°C to +170°C, which is essential for applications exposed to varying environmental conditions.
