Ideal precision shunt for extreme conditions

Ideal precision shunt for extreme conditions

When you're working on the design of a power application for extreme temperature conditions and you'd like to measure voltage or current, you might run into limitations. When the internal temperature of your application is rising, the constant load capacity of your shunt decreases and the long-term stability is put to the test.

Gold-plated bondable resistors
The new PMH-D and PLU precision performance foil resistors from Isabellenhütte are produced using the Isa-Plan process. In this process, three layers of manganin foil, copper substrate and an adhesive with good thermal conductivity (ceramic filled) are pressure bonded. This highly temperature-resistant bonded combination of substrate and resistant foil ensures optimal dissipation of heat. A small increase in the temperature of the component has a positive effect on stability and long-term drift. That is why both resistors are well suited to applications in the automotive sector in which there are high requirements in terms of temperature and load. They meet the international AEC-Q200 specifications. The PMH-D and PLU are also used in industrial applications such as frequency converters and power modules with DCB ceramic substrates.

5W at 150 °C
The PMH-D (6.7 x 3.4 x 0.7 mm) and the PLU (10.4 x 6.4 x 0.6 mm) are designed for hybrid mounting with bonding technology. The bonding pads and the back side of the component are plated with a 0.1 μm layer of gold. That makes soldering and mounting with conductive adhesive possible. The result is an ideal thermal coupling that makes best use of the available component surface. The resistors are designed to handle a constant load of up to 5 W at 150 °C and a constant current of up to 50 A (PMH-D / size 2512) and 70 A (PLU / size 3924). The PMH-D is currently available as a 2-mOhm resistor and the PLU as a 1-mOhm resistor. Both resistors are designed as four-wire measurement resistors (Kelvin connection) and fulfil the requirements of RoHS guideline RoHS 2011/65/EU.
