Power resistors handle high-speed pulses

TO-247-packaged power resistors feature a very low inductance, making them ideal for high frequency and high-speed pulse applications.

Providing design engineers with a high-power resistive device in a stable transistor style package, TT Electronics IRC Advanced Film Division's MHP Series TO-247 power resistors are available in 100 and 140W packages.

According to Gary Bleasdell, Thick Film Business Unit Director for IRC Advanced Film Division, the resistors are specified for applications that require accuracy and stability.

"The MHP Series resistors are designed with an alumina ceramic layer that separates the resistance element and mounting tab", says Bleasdell.

"This construction provides very low thermal resistance while ensuring high insulation resistance between the terminals and the metal back plate".

"As a result, the resistors feature a very low inductance, making them ideal for high frequency and high-speed pulse applications".

Additional applications for the MHP Series TO-247 resistors include automation test equipment, high frequency snubber and pulse handling circuits, motor control and drive circuits, switch mode power supplies, load resistors, automotive electronics, industrial power equipment, UPS systems and industrial computers.

MHP Series 100 and 140W resistors feature a resistance range of 0.01 to 220ohm, inductance value below 50nH and a voltage rating of 700V.

Absolute tolerances are to +/-1 and +/-5%, with absolute TCRs to +/-100ppm/C.

Operating temperature range is -40 to +85C.

IRC will also produce devices outside these specifications to meet customer requirements.

The MHP Series power resistors are available with RoHS-compliant terminations.

Pricing for the MHP Series TO-247 power resistor is US $4.58 each in quantities of 1000.

Lead time is from stock to 10 weeks.
