Note: Temperature rise data are given here for typical mounting conditions. Actual figures depend on PCB copper weight, mounting pad size, track

width and substrate type. Also, the open air format responds better to forced air cooling than chip format resistors. For values below 5 milliohms

allowance should be made for heat generated in the copper tracks themselves. Application-specific guidance is available on request.

OARS, OARS-XP, OARSZ Series

Thermal Performance Examples

OARS1-R005 at 2W

OARSXP-R0025 at 5W

These thermal images were taken under ambient conditions of still air at 25°C with the components

mounted on horizontal standard test boards as defined below.

JEDEC standard circuit board:

2” (50.8mm) square FR4

2 outer power planes, 2 ounce (70μ) Cu

1” (25.4mm) square exposed

2 inner signal planes, 1 ounce (35μ) Cu

(continuous planes)

In contrast to the flat chip format, the OARS format keeps the hot spot thermally distant from the

solder j oints and reduces undesirable heat delivery into the PCB. Further thermal images for other

ohmic values and power dissipations are available on request.

Kelvin (4 Terminal) Mounting

For high precision applications a Kelvin (4

Terminal) mounting method is

recommended. An example to illustrate the

design principle is shown. High current

connections are made to the two pairs of

larger pads, whilst the voltage sense

connections are made to the two smaller

central pads.

Construction

Copper terminations are welded to resistance alloy strip which is then formed. Value adjustment is achieved

by control of width, without the need for subsequent abrasion or notch trimming.

Pb-free termination finish is 96% Sn / 4% Ag alloy.

Flammability

The resistor will not burn or emit incandescent particles under any condition of applied temperature or overload.

Marking

The parts are legend marked with ohmic value and tolerance code.
