Common Mode Chokes Overview

The DCM191320V-473NHF is a two-line common mode choke manufactured by ITG Electronics, Inc., designed for through-hole mounting. It provides an inductance of 47 mH at a test frequency of 10 kHz. The component supports a maximum current rating of 350 mA and features a DC resistance (DCR) of 2.75 Ohms. It operates within a temperature range of -55°C to +130°C and meets UL Class B compliance standards.

Common Mode Chokes Feature Summary

• Two-line configuration for effective noise suppression
• Through-hole mounting for secure PCB integration
• UL Class B compliant insulation system
• RoHS and HF compliant construction

Common Mode Chokes Applications

• Switch mode power supply input filtering
• EMI suppression in AC/DC converters
• Signal line noise reduction in electronic equipment

Common Mode Chokes Procurement Notes

Verify the specific suffix 'NHF' against the manufacturer's latest datasheet to confirm RoHS and halogen-free status. Ensure the through-hole pin spacing matches the target PCB footprint. Confirm that the 350 mA current rating aligns with the application's peak load requirements to prevent saturation or excessive heating during operation.

Common Mode Chokes Selection Notes

Select this component when high inductance is required for low-frequency noise attenuation in two-wire lines. The 2.75 Ohm DCR must be evaluated against the circuit's voltage drop constraints. Consider the physical size and thermal dissipation capabilities relative to the enclosure environment, as the operating temperature extends up to 130°C.

Common Mode Chokes Part Context

This part belongs to the DCM191320V series of common mode chokes from ITG Electronics. The series offers various inductance values tailored for different noise suppression needs while maintaining consistent mechanical and electrical safety standards.
