Overview
The B82723A2402N001 is a current-compensated ring core double choke designed for power line applications. It features a rated AC voltage of 250 V and a maximum rated current of 4 A. The inductance is specified as 2.7 mH at 10 kHz, with a typical DC resistance (DCR) of 60 mOhm. The component utilizes through-hole mounting and operates within a temperature range of -40°C to 125°C. Maximum physical dimensions are 28.00 mm in length, 27.00 mm in width, and 16.80 mm in height.
Feature Summary
- Current-compensated ring core design for effective common mode noise suppression
- Dual-line configuration suitable for power line filtering
- Through-hole mounting for robust mechanical integration
Applications
- Power line EMI filtering
- Common mode noise suppression in electronic equipment
- AC power input stages
Procurement Notes
Verify the specific part number against official TDK/EPCOS documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with existing board layouts regarding through-hole spacing and height constraints. Confirm that the 250 V AC rating and 4 A current capacity meet the target application requirements before procurement.
Selection Notes
Select this component when a current-compensated choke is required for dual-line power filtering. The 2.7 mH inductance value should be evaluated against the specific frequency spectrum of the noise to be suppressed. Consider the 60 mOhm DCR impact on power loss and the thermal performance within the -40°C to 125°C operating range.
Part Context
This component belongs to the B82723A series of power line chokes manufactured by EPCOS, now part of TDK Electronics. These devices are engineered for general-purpose electromagnetic interference suppression in AC power circuits, offering a balance of high inductance and low DC resistance for efficient noise reduction.
Replacement Considerations
Consult official TDK/EPCOS substitution guides for verified alternatives. Ensure any replacement maintains the same current compensation topology, inductance tolerance, and physical footprint to guarantee functional equivalence in the circuit design.
