PCIM 2014: Isabellenhütte presents a family of resistors with gold-plated contacts

Isabellenhütte presents the VMx-A, a member of the VMx precision resistor family with gold-plated contacts. The established and gold-plated series have very high pulse-load capacities and outstanding long-term stability. The VMx-A versions of the resistors are not just suitable for component mounting by means of reflow and IR soldering, they can also be mounted with conductive adhesive. The advantage of the gold-plating is that it allows models such as the VMP-A to be used in high-temperature applications. That makes it ideal for high-density integration applications and enables bonding with high-temperature circuit boards.

The VMP-A is certified according to the AEC-Q200 quality standard for electrical components in the automotive industry. Thanks to its small size (type 2010: 5.08 x 2.54 x 0.4 mm), high load capacity and precision, it is a popular choice for automobile engine and transmission modules. Further applications for the VMP-A include power hybrids and power modules (DCB ceramic) in frequency converters. The gold-plated VMP-A resistor has a constant load capacity of up to 2 W at 110 °C and can handle a constant current of up to 20 A. Its temperature range is -55 to 170 °C.

Technical details, VMP-A:
Resistance values 25 / 80 / 100 / 200 mOhm
Tolerance 1 / 5 %
Temperature coefficient (20-60 °C) < 20 ppm/K
Temperature range -55 to +170 °C
Load capacity 2 W
Inner thermal resistance < 30 K/W
Inductance < 2 nH
Dielectric strength 200 V AC/DC
Stability (nominal load) < 0.5 % (TK = 80 °C)
Deviation after 2,000 hrs < 1.0 % (TK = 110 °C)
TK = contact point temperature

About Isabellenhütte Heusler
Isabellenhütte Heusler GmbH & Co. KG has been owned by the Heusler family since 1827. Today, the company is an international leader in the production of low-ohmic precision and power resistors. Other business units are dedicated to the production of precision alloys, while the measurement technology designed by Isabellenhütte is considered to lead the field of shunt-based current measuring systems. The company combines its precision measuring systems under the new brand name ISAscale®. Around 720 staff are employed at its headquarters and production works in Dillenburg, Hesse.
