MagI³C-FISM Fixed Isolated SIP/SMT Module
Würth Elektronik fixed isolated SIP modules provide compact power and are suitable for reliable isolation
The Würth Elektronik MagI³C-FISM modules provide compact, fixed-input isolated DC/DC converters for functional isolation in industrial and communication systems. They integrate the transformer, control circuitry, and capacitors in SIP-7 or SMT-8 packages, enabling simple plug and play use.
Characteristics
- Nominal input rails: 3.3 V, 5 V, 12 V, and 24 V
- Output voltage: 5 V (unregulated), no minimal load
- Output current/power: 0.2 A (1 W) or 0.4 A (2 W), with short-term boost capability
- Efficiency: Up to 88%
- Isolation: 3 kV DC for 60 s (4 kV DC for 1 s on select models)
- Output ripple: 55 mV to 75 mV at full load
- Operating temperature: -40°C to +105°C
- Packages: SIP-7 THT and SMT-8 SMD
Features
- Integrated transformer and capacitors (no external components required)
- Continuous short-circuit protection (3 kV/4 kV and 2 W devices)
- Low conducted and radiated EMI (compliant to EN55022 Class B)
- UL60950 certified
- RoHS and REACH compliant
- Simple, fixed-duty isolation design
- Functional isolation for breaking ground loops, noise suppression, and interface protection
Applications
- Data acquisition
- Test and measurement systems
- Interface and microcontroller supplies
- Industrial controls
