Bright LED technology thanks to correct resistors

LED technology is becoming an increasingly popular choice for lighting up the headlights of modern cars as well as their displays and cockpits. Special resistors are necessary to make the diodes work properly.

LED (light emitting diode) technology provides automotive suppliers with a challenge: The rear part of the light unit leaves only little space for installation and the law requires a minimum brightness level. On...

Isabellenhütte is launching the VLx resistor series, resistors with unmatched performance. Reversing the length to width ratio resulted in expanding the resistance range to extremely low values (i. e. 1mOhm in size 0612) and enabled other remarkable improvements. The larger soldering and contact pads are increasing the mechanical stability of the solder joints during temperature and power cycling and guaranty at the same time a much better heat flow into the PC board. A new mechanical...

Isabellenhütte is presenting the IPC series of current measurement modules for the motor phase current on measurement shunt basis at the PCIM and Sensor+Test trade fairs. The modules were designed to control electric high-performance motion control units of all types. The data acquisition runs at sampling rates from 10 to 300 kHz. A programmable sampling delay time triggered with an external signal is supported. The modules also supply a fast over current signal (response time < 2...

Lithium-ion battery charging and discharging periods pose a great challenge for current and voltage measurement. At electronica, Isabellenhütte Heusler is presenting a sensor module (IMC) tailored to these needs. It can be completely configured according to customer requirements.

For use in hybrid and electric vehicles, precision and component size are crucial factors. The small, and therefore space-saving, IMC (shunt: 20 x 85 mm, board 20 x 40 mm) can perform measurements within...

SMx resistors in the Columbus space laboratory

The European Columbus laboratory is now in space, and precision resistors from the Isabellenhütte SMx series are on board. It is by no means easy to fulfil the stringent requirements set by aerospace and space organisations. Components must function reliably even when subjected to extreme influences. For example, the SMx series resistors for use in space can endure the vibrations which occur when the shuttle lifts...
