New IRC Resistor Features Low Thermal Resistance in High-Power Package
TT electronics IRC Advanced Film Division announced the MHP20S Series TO-126 resistor, which features a non-inductive thermal resistant design and is rated up to 20W. The device is said to provide design engineers with a compact, high-power resistive device for applications with limited PC board space.
"The MHP20S power resistor features a complete thermal design, allowing for power ratings that normally wouldn’t be realized in a TO-126 package," said Gary Bleasdell, Thick Film Business Unit Director for IRC Advanced Film Division. "The high-power capability in the space-saving design makes the resistor ideal for power circuit applications, particularly those in automatic test equipment."
Within automatic test equipment applications, the MHP20S resistor is specified for pin driver use in IC and board testers. Additional applications include pulse handling circuits, motor control and drive circuits, and switch-mode power supplies.
The MHP20S Series 20W resistors feature a resistance range of 0.01 to 220Ω, with a thermal resistance of 5.9°C and a dielectric withstanding voltage of 2000Vdc. Absolute tolerances are to ±1% and ±5%, with absolute TCR to ±50ppm/°C. Operating temperature range is -55 to +155°C. IRC will also produce devices outside these specifications to meet customer requirements.
Pricing for the MHP20S Series TO-126 power resistor is $0.52 each in quantities of 500 pieces. Lead time is from stock to 8 weeks.
