By using superior grades of core material, MCI´s 4-82 series transformers are suited to operate at switching frequencies up to 1MHz. These transformers are designed to meet UL and CSA requirements and are Hipot tested at 1000VRMS standard with higher voltages available. MCI´s 4-82 Series utilizes standard materials for quick turnaround of custom variations. MCI´s "State of the art" manufacturing facilities provide automatic assembly and 1005 final testing to guarantee a high quality part. Our design engineers are knowledgeable regarding switchmode magnetics and can provide many solutions for your overall switching power application.

The above transformers can be used in four topologies, flyback, forward, pushpull, and bridge converters. For supplies in the 5-110 watt range the flyback is recommended. It has the least parts count, only one input switching devices, and no output inductor or freewheeling diode. It also exhibits excellent tracking between multiple outputs.
