Surface mount power resistors handle up to 10W

With the highest power rating currently available, SMP series surface mount power resistors help designers of high power applications in confined spaces.

BI Technologies has developed a surface mount power resistor it claims has the highest power rating currently available.

The SMP series is unique in its ability to offer designers of high power applications a resistor with a power capability of up to 10W.

Designed for use in high power applications in confined spaces, the SMP series boasts a small footprint and moulded SOIC package that offers superior thermal management.

The power resistor boasts extremely low thermal resistances in each axis to achieve maximum heat dissipation.

By conducting heat from the resistive element through low thermal impedance metallic pathways to the package surfaces, the board efficiently channels heat away from the resistor to the ambient.

This allows designers to create a product that can operate at higher output power levels, short term overloads and pulse durabilities without the normal thermal problems.

The SMP series is suitable for a variety of applications, including high frequency emitter resistors in switching power supplies, high precision CRT colour video amplifiers, high frequency snubber and pulse handling circuits, pulse generator load resistors and in-rush current protection, as well as bleeder resistors.

The series offers tolerances of +/-1 and +/-5% and an operating temperature range of -55 to +155C.

Exhibiting a resistance range up to 10kohm and excellent heat dissipation qualities, it offers designers enhanced power handling capabilities and increased protection from the threat of common overheating problems.

John Mackay, Managing Director of BI Technologies said: "As the popularity of surface-mount technology grows, product designers increasingly find themselves faced with the combined challenge of dissipating power from components, whilst removing the generated heat from the component and circuit board".

"This latest product will present designers with a product capable of solving these problems while offering a high power capability".
