Overview
The B82730U3601A020 is a current-compensated U-core double choke from the EPCOS (TDK) B82730U series. It features a rated AC voltage of 300 V and a maximum DC current rating of 600 mA. The inductance value is 4.7 mH with a typical DC resistance of 920 mOhm. Designed for through-hole mounting, it utilizes a vertical 4-pin package configuration. The component operates within a temperature range of -40°C to +125°C and holds UR and VDE approval agencies.
Feature Summary
- Current-compensated design for power line noise suppression
- U-core construction for efficient magnetic coupling
- Through-hole vertical pin configuration for PCB integration
Applications
- Power line filtering in electronic equipment
- EMI suppression in AC input stages
- Common mode noise reduction in single-phase circuits
Procurement Notes
Verify the specific suffix A020 against official TDK/EPCOS documentation to confirm pinout and mechanical dimensions. Ensure the 300V AC rating and 600mA current limit align with your circuit requirements. Confirm RoHS compliance status via the latest datasheet revision. Cross-reference the UR and VDE approvals with regional safety standards applicable to your final product assembly.
Selection Notes
Select this component when a 4.7 mH inductance is required for common mode noise attenuation at 600 mA. The 300V AC rating suits standard mains applications. The vertical through-hole package facilitates manual or wave soldering processes. Consider the operating temperature range if the environment exceeds standard industrial limits.
Part Context
This part belongs to the B82730U/G series of current-compensated frame core double chokes. These components are designed for power line applications with rated voltages up to 300 V AC. The series offers various inductance values ranging from 0.33 mH to 15 mH, catering to different filtering needs in single-phase systems.
Replacement Considerations
Check for direct substitutes within the B82730U series with matching inductance and current ratings. Verify mechanical compatibility for through-hole mounting. Ensure equivalent electrical characteristics such as DC resistance and saturation current before substitution.
