Thick Film Technology Power Resistors

20 Watt and 30 Watt TO220 Package

FEATURES

• Available with 20 or 30 Watt power rating

• Convenient TO220 package

• 20 Watt: Resistance range 1 Ω to 1 MΩ

• 30 Watt: Resistance range 0.5 Ω to 100 KΩ

• Tolerance 1 ꢀ standard

• TCR to 50 ppm/°C

• Non-Inductive Design

• Isolated electrical element

The well known TO-220 package combined with the proven

thick film technology provides you, the design engineer, with

a high reliable and cost effective solution for applications

requiring current limiting/current sensing.

ELECTRICAL SPECIFICATIONS

Resistance Range: 20 Watt: 0.5 Ω to 100 kΩ

30 Watt: 0.5 Ω to 100 KΩ

STD Resistance Tolerance: 1 ꢀ, 2 ꢀ, 5 ꢀ and 10 ꢀ

(Tighter available)

The chips unique attachment to the solder coated copper

base provides a repeatable low thermal resistance path for

the energy to exit the resistor and be dissipated into the

heatsink.

Power Dissipation:

TRP20:

20 Watts at 25 °C with heatsink

2 ¼ Watts at 25 °C without heatsink

TPR30:

The popular TO-220 package can be handled easily by the

manufacturing group.

30 Watts at 25 °C with heatsink

2 ½ Watts at 25 °C without heatsink

Temperature Coefficient: 100 ppm/°C Std

( 50 ppm/°C available)

Vishay has additional solutions when higher Technical
