SNCMC-127-012

Overview

The SNCMC-127-012 is a nanocrystalline common mode choke manufactured by Signal Transformer. It features a vertical through-hole mounting style and operates within a temperature range of -25°C to +130°C. The component provides an inductance of 17.1 mH at a test frequency of 10 kHz, with a maximum DC current rating of 10 A. Its impedance is specified as 4.18 kOhms at 100 kHz. The physical dimensions are 37 mm in length, 25 mm in width, and 35 mm in height. It is unshielded and complies with RoHS standards.

Feature Summary

• Utilizes nanocrystalline core material for effective common mode noise suppression
• Designed for vertical through-hole PCB mounting
• Capable of handling high DC currents up to 10 A

Applications

• Common mode filter chokes
• Suppression chokes
• Power line filtering

Procurement Notes

Verify the specific manufacturer designation, as sources attribute this part to both Bel Signal Transformer and Signal Transformer. Confirm RoHS compliance status and lead thickness specifications (1.3 mm) against the latest official datasheet before integration. Ensure the nanocrystalline construction aligns with thermal requirements for the target application environment.

Selection Notes

Select this component when high current handling and significant common mode attenuation are required in a vertical form factor. The nanocrystalline core offers superior performance compared to standard ferrite cores for broadband noise suppression. Verify that the 10 A saturation current meets the circuit's peak load demands and that the unshielded design does not interfere with nearby sensitive components.

Part Context

This part belongs to the SNCMC series of common mode chokes from Signal Transformer. It is distinct from the SCRH series, which consists of shielded surface mount power inductors. The SNCMC series focuses on through-hole applications requiring robust noise filtering capabilities for power lines.
