Hello my name is Nelson Garcia and I am the Engineering Manager for Renco Electronics. Today we are highlighting an exciting series of high current drum inductors known as the RL 5480HC.  The RL 5480HC is the high current version of the ever popular RL-5480 series. 

The RL-5480 has been in production for many years and has really shown a resurgence in popularity in the last 8 years in power supplies for smart meter and LED lighting applications.

In the last few years the RL-5480 and now the RL-5480HC series have been designed into LED replacement bulbs.  For example, this 40 watt LED bulb contains an 8 W power supply on a PC board similar to this board. Now on this board there are two RL-5480 drum inductors in the EMI filter section.

This power supply and LED bulb is a good example of how the RL-5480HC series came about.  The challenge for customers designing LED bulbs is to continually improve their designs and reduce the size of the components in the power supplies. After a few similar requests for a smaller version of the RL-5480 series, we went to the drawing board and came up with the RL-5480HC series.   The RL-5480HC series allows you to use a smaller part, but still have the same if not better saturation current performance. 

For a size comparison, this is the RL-5480-3 size in black sleeving, and this is the RL-5480HC-2. Not only is this part smaller, but it has the same if not better saturation current performance!  The RL-5480HC is also is available in 5 different sizes and the same large variety of inductance values as the RL-5480 series.

The RL-5480HC series is in stock now and available for samples and production.
