MagI³C-FISM Fixed Isolated SIP/SMT Module

The Würth Elektronik MagI³C-FISM fixed isolated SIP/SMT power modules offer a compact and easy-to-use solution for providing functional isolation in industrial and signal applications. These modules are ideal for isolating interfaces and breaking ground loops in communication systems.

MagI³C-FISM modules are available with fixed input voltages of 3.3 V, 5 V, 12 V, and 24 V, delivering a 5 V unregulated output with no minimum load requirement. The fully integrated solution includes internal input and output capacitors, as well as a transformer, enabling a plug-and-play design with minimal external components.

Housed in standard SIP-4 or SIP-7 packages, these modules are optimized for space-constrained designs while maintaining high efficiency of up to 81% at full load (24 V to 5 V, 0.2 A in SIP-7). With functional isolation up to 1 kV_DC (up to 4 kV_DC for select models), low output ripple, and compliance with EN55022 Class B EMI standards, the MagI³C-FISM modules ensure clean power for sensitive analog, sensor, or communication systems. MagI³C-FISM modules are UL60950 certified.
