Dillenburg, Germany 15th of May 2014
PCIM 2014: Isabellenhütte presents a family of resistors with gold-plated contacts
The VMx-A series of gold-plated low-ohmic resistors for mounting
with conductive adhesive on high-temperature circuit boards
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 pulseload 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.
