- Dual-line configuration for common mode noise suppression
- Robust thermal performance across extended industrial temperature ranges
Applications
- Power supply input filtering
- Signal line noise suppression
- EMI reduction in electronic circuits
Procurement Notes
Verify component status as the 3000-182 is listed as obsolete or discontinued by major distributors. Confirm availability through secondary markets or alternative sourcing channels if immediate procurement is required. Check RoHS compliance status, as some sources indicate non-compliance. Ensure replacement parts are evaluated for mechanical and electrical equivalence before integration into new designs.
Selection Notes
Select this component when a 1.8 mH inductance value is required for common mode noise attenuation in through-hole applications. Consider the 260 mA current rating and 2.8 ohm DC resistance limits during circuit design. Evaluate the radial package dimensions against available PCB space. Compare against other series components if higher current handling or different inductance values are needed.
Part Context
This component is part of Bourns' 3000 series of common mode chokes. The series offers various inductance values and current ratings for general-purpose filtering. The 3000-182 specifically targets applications requiring moderate inductance with through-hole assembly. It serves as a passive electromagnetic interference suppression device in power and signal lines.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify equivalent specifications from other manufacturers if direct replacement is necessary.
