Overview
The B82725A2123N2 is a current-compensated ring core double choke from the B82725A series, manufactured by EPCOS (TDK). It is designed for power line filtering applications with a rated AC voltage of 250 V. The component features an inductance of 1 mH and supports a continuous current of 12 A. Its DC resistance is specified at 12 mOhm. The device utilizes a horizontal through-hole mounting configuration with four pins. Physical dimensions include a length of 44.00 mm, width of 42.40 mm, and maximum height of 25.00 mm. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Current-compensated ring core construction for effective common-mode noise suppression
- Dual-line design suitable for differential mode interference reduction
- High current handling capability of 12 A with low DC resistance
- Robust thermal performance across extended industrial temperature ranges
Applications
- Power supply input filtering
- Battery charger circuits
- Portable electronic device power stages
- Voltage regulation modules
Procurement Notes
Verify part authenticity against EPCOS TDK official documentation. Confirm RoHS3 compliance status as indicated in distributor listings. Check for obsolete status warnings associated with this specific model number. Ensure packaging details match standard tray quantities if applicable. Validate pin configuration and mounting orientation against schematic requirements.
Selection Notes
Select this component when high current capacity and compact form factor are required for power line chokes. Compare inductance values against similar models like B82725A2123N40 for different filtering needs. Consider the 12 A rating for heavy-duty applications. Evaluate thermal constraints within the -40°C to 125°C operating range. Verify mechanical fit within the 44.00 x 42.40 x 25.00 mm envelope.
Part Context
This component belongs to the B82725A family of power line chokes. It shares physical dimensions and mounting styles with other variants in the series, such as B82725A2123N40 and B82725A2122N20. These parts are commonly used in EPCOS TDK filter solutions for industrial and consumer electronics. The series emphasizes high efficiency and reliability in electromagnetic interference suppression tasks.
Replacement Considerations
B82725A2123N40 offers higher inductance (3.3 mH) with identical current ratings. B82725A2122N20 provides lower inductance (1 mH) but reduced current handling (1.2 A). Cross-reference datasheets for electrical compatibility before substitution.
