Overview
The VCMC2618-333N is a through-hole common mode choke manufactured by Allied Components International. It features two lines with an inductance of 33 mH measured at 10 kHz and a tolerance of 30%. The component has a current rating of 800 mA and a DC resistance (DCR) of 850 mΩ. It withstands 1.5 kV voltage and operates within a temperature range of -25°C to +125°C.
Feature Summary
- Provides common mode noise suppression for dual-line circuits
- Designed for through-hole mounting applications
- Operates reliably across a wide temperature range
Applications
- Signal line filtering in electronic devices
- Noise suppression in data transmission interfaces
- Power supply input filtering
Procurement Notes
Verify the part number VCMC2618-333N against official Allied Components International documentation to confirm specifications such as 33 mH inductance and 800 mA rating. Ensure compatibility with through-hole assembly processes and check that the 1.5 kV withstand voltage meets circuit requirements. Confirm operating temperature range suitability for the intended environment.
Selection Notes
Select this component when dual-line common mode noise reduction is required for signals carrying up to 800 mA. The 33 mH inductance provides effective filtering at relevant frequencies. Ensure the PCB layout supports through-hole mounting and that the 850 mΩ DCR aligns with power loss constraints. Verify that the 1.5 kV isolation rating satisfies safety standards for the application.
Part Context
This component belongs to the VCMC2618 series of common mode chokes from Allied Components International. The series offers various inductance values and current ratings for different filtering needs. The VCMC2618-333N specifically targets applications requiring moderate inductance and current handling capabilities in a through-hole package.
Replacement Considerations
Check for direct substitutes with identical 33 mH inductance, 800 mA rating, and through-hole form factor. Ensure equivalent DCR and voltage withstand capabilities. Verify pinout compatibility if replacing in existing designs.
