SU10VFC-R03370

Overview

The KEMET SU10VFC-R03370 is a vertical through-hole common mode choke designed for AC line filtering applications. It features a nominal inductance of 37 mH measured at 1 kHz and supports a maximum rated current of 300 mA. The component has a DC resistance (DCR) of 4.2 ohms and is rated for an AC voltage of 250 V. It operates within a temperature range of -25°C to 120°C and utilizes a four-pin vertical package with dimensions of 18.00 mm length, 15.50 mm width, and a maximum height of 15.00 mm.

Feature Summary

• Provides common mode noise suppression for two-line AC power circuits
• Constructed for vertical through-hole mounting on printed circuit boards
• Engineered for high-frequency interference attenuation in power supply inputs

Applications

• AC power line input filtering for electronic equipment
• Noise suppression in consumer appliance power stages
• EMI reduction in industrial control power supplies

Procurement Notes

Verify the specific datasheet version (e.g., V01) against the manufacturer's official documentation to confirm dimensional tolerances and electrical ratings. Ensure the procurement specification matches the required 37 mH inductance at 1 kHz and the 300 mA current rating. Confirm compliance with RoHS3 standards if environmental regulations apply to the final assembly. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when designing AC power inputs requiring significant common mode noise attenuation at low frequencies. The 37 mH inductance value is suitable for standard mains frequency filtering. Consider the 4.2 ohm DCR impact on voltage drop and thermal dissipation at the full 300 mA load. The vertical form factor requires adequate board clearance for the 15.00 mm height. Verify that the operating environment stays within the -25°C to 120°C range for reliable performance.

Part Context

This component belongs to the KEMET SU series of common mode chokes, which are specialized for AC line filtering. The SU series typically offers robust construction for mains voltage applications. The SU10VFC-R03370 specifically targets general-purpose AC line noise suppression, distinguishing itself from high-frequency or differential mode variants by its higher inductance and lower current handling capabilities compared to larger industrial chokes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. When evaluating alternatives, match the 37 mH inductance, 300 mA current rating, 250 V AC rating, and 4.2 ohm DCR. Ensure the replacement maintains the vertical through-hole footprint and similar physical dimensions to fit existing board layouts.
