VMK and VLK resistors
Isabellenhütte Heusler has introduced the VMK and VLK ranges of resistors, which are designed to be compact and robust to suit use in LED technology.
VLK resistors have long-side termination, which is claimed to make them less susceptible to temperature and load cycles.
Both these and the VMK resistors are claimed to provide high performance in a small space.
Component assembly is achieved via reflow and IR soldering.
