FAE Expert Insights
"The CFM05S050 is an excellent choice for low-power IoT and embedded applications requiring AC input. The universal 85-264VAC input is a major advantage - no voltage selection switches or different SKUs for different regions. I've used this module in smart home devices, IoT sensors, and industrial controls with excellent results. The encapsulated package provides good environmental protection and makes thermal management easier through conduction cooling. The 3000VAC isolation meets safety requirements for most applications. The 78% efficiency is good for this power class and price point. For 5V, 5W applications, this module offers the best balance of features, size, and cost. I recommend adding a small heatsink or mounting on metal chassis for thermal management. The global certifications simplify end-product approval."
I highly recommend the CFM05S050 for its proven reliability.

Frequently Asked Questions
What is the pinout of the CFM05S050?
The CFM05S050 has the following pinout: AC Input Pins: AC (L) - Line input, AC (N) - Neutral input; DC Output Pins: +Vout - Positive output, -Vout - Negative output/ground. Pin spacing is 2.54mm (0.1 inch) standard pitch. The module can be mounted using through-hole pins or soldered directly to PCB. For thermal management, the encapsulated case can be mounted against a metal surface or heatsink using thermal interface material. Always observe correct AC polarity for safety, though the module will work with reversed input. Include a fuse in the AC input line for safety protection. Refer to the datasheet for exact dimensions and recommended PCB layout.
Follow datasheet pinout for PCB layout. Include input fuse for safety. Contact us for layout review.
How do I meet EMC requirements with the CFM05S050?
The CFM05S050 is designed to meet EN55032 Class B with appropriate external filtering. For EMC compliance: Input filtering: Add common mode choke on AC input; Add X capacitor across AC lines; Add Y capacitors for common mode noise. Output filtering: Add output capacitors for differential noise; Use ferrite beads on output if needed. Layout: Keep AC input traces short and separated from DC output; Use ground plane for shielding; Minimize loop areas. The module includes internal filtering but external components may be needed depending on your specific application and enclosure. For Class B compliance in plastic enclosures, additional filtering is typically required. For metal enclosures with proper shielding, internal filtering may be sufficient. Contact our FAE team for EMC design assistance and recommended filter circuits.
Add external EMI filter for Class B compliance. Use metal enclosure for better shielding. Contact us for EMC design.
What hold-up time can I expect from the CFM05S050?
The CFM05S050 provides typical hold-up time of 10-20ms at full load and nominal input voltage. Hold-up time is the duration the output remains regulated after AC input is removed. The hold-up time depends on: Input voltage: Higher voltage provides longer hold-up; Load current: Lower load extends hold-up time; Output capacitance: Additional capacitance increases hold-up. For applications requiring longer hold-up: Add external bulk capacitance on output; Use a larger module operating at partial load; Consider a UPS or backup power solution. For most applications, 10-20ms is sufficient to ride through AC line transients and brief interruptions. For critical applications requiring longer hold-up, calculate required capacitance: C = (2 × P × t) / (V² - Vmin²), where P is power, t is time, V is nominal voltage, Vmin is minimum operating voltage. Contact our FAE team for hold-up time calculations.
Standard 10-20ms hold-up for most applications. Add external capacitance for longer hold-up. Contact us for calculations.
Can the CFM05S050 be used in medical applications?
The CFM05S050 has 3000VAC isolation which meets basic safety requirements, but for medical applications requiring patient contact, additional considerations apply: The module has 3000VAC isolation suitable for MOOP (Means of Operator Protection); For 2xMOPP (Means of Patient Protection) applications, additional isolation may be required in the system design; Patient leakage current must be evaluated in the complete system; The module is not specifically certified to IEC 60601-1. For medical applications: Evaluate the complete system against IEC 60601-1 requirements; Consider additional isolation barriers if needed; Test patient leakage current in the final configuration; Consider Cincon's medical-grade AC-DC modules for applications requiring medical certifications. Contact our FAE team for medical application design assistance and evaluation of specific requirements.
Evaluate against IEC 60601-1 for medical use. Consider medical-grade modules for patient contact. Contact us for medical design.
What inrush current can I expect at startup?
The CFM05S050 has typical inrush current of 20-30A peak for <1ms at 230VAC cold start. Inrush current occurs when the input capacitors charge at startup. Considerations for inrush current: Duration: Very brief (<1ms), so thermal impact is minimal; Frequency: Higher at cold start, lower at warm start; Input voltage: Higher voltage produces higher inrush. For system design: Input fuse should be slow-blow type to avoid nuisance tripping; Circuit breaker should have appropriate trip curve; Consider NTC thermistor or active inrush limiter for high-power systems. For multiple modules, staggered startup may be needed to reduce total inrush. The inrush current is within normal limits for this power class and is comparable to competitor products. For systems with strict inrush limits, contact our FAE team for inrush limiting solutions.
Use slow-blow fuse for inrush tolerance. Consider inrush limiter for multiple modules. Contact us for high inrush applications.
