Vishay’s New D2TO35 35-W Thick Film Power Resistor Features Wide 0.01-Ω to 550-kΩ Resistance Range in Ultra-Compact TO-263 Package (D2PAK)
Non-Inductive Device Offers Standard Tolerances of ±1 % to ± 10 % and Supports Soldering Temperatures at +270 °C
MALVERN, PENNSYLVANIA — June 25, 2008 — Vishay Intertechnology, Inc. (NYSE: VSH) today released a new 35 W thick film power resistor featuring 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 0.01 Ω to 550 kΩ. Packaged in the very small TO-263, which measures a mere 10.1 mm by 10.4 mm with a low 4.5-mm profile, the resistor saves valuable space on the circuit board, allowing designers to reduce the size of their end products.
The device released today 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 35 W and +25 °C is 4.28 °C/W junction-to-case. The resistor features a standard temperature coefficient of ±150 ppm/°C at resistance values of ≥ 0.5 Ω, with standard tolerances of ±1 % to ±10 %.
Connections for the new resistor are tinned copper, and they are specified for operation over a -55 °C 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.
