Vishay Releases New 35W Thick Film Power Resistor With 0.01&Omega To 550kΩ Resistance Range
Vishay Intertechnology, Inc. released a new 35W thick film power resistor featuring what is described as a compact, easy-to-mount TO-263 package (D²PAK) and a broad range of resistance values.
The new D2TO35 thick film resistor is non-inductive and provides a wide resistance range of 0.01Ω to 550kΩ. Packaged in the small TO-263, which measures 10.1 x 10.4mm with a 4.5mm profile, it is claimed that the resistor saves valuable space on the circuit board, allowing designers to reduce the size of their end products.
The device is intended for power supply, current sensing, power conversion, high-speed switching, RF, pulse generation, load resistor, snubber, pulse-handling circuit, and amplifier applications in end products including industrial welding machines, test equipment, UPS, locomotive, automotive, and base station systems.
Thermal resistance for the D2TO35 at 35W and +25°C is 4.28°C/W junction-to-case. The resistor features a standard temperature coefficient of ±150ppm/°C at resistance values of �0.5Ω, with standard tolerances of ±1% to ±10%.
Connections for the new resistor are tinned copper, and they are specified for operation over a -55 to +175°C temperature range. The device is RoHS-compliant, and supports soldering temperatures at +270°C.
Samples and production quantities of the D2TO35 thick film power resistor are available now, with lead times of eight to 10 weeks for larger orders. Pricing for U.S. delivery in minimum order quantities is $2.90 per piece, and $1.90 per piece in high-volume orders.
