We are offering finest grades of storage chokes, which are used to store energy in switched-mode power supply (SMPS). As a standard, these are made using iron or metal powder cores having single winding only. As the load current increases, there is a decrease in the inductance value. In line with this, operating point of the load current is chosen in the range of sixty to seventy five percent of no-load inductance. The storage chokes are susceptible to thermal aging.
