B82730G3451A020

Overview

The B82730G3451A020 is a current-compensated U-core double choke designed for power line applications. It features a common mode inductance of 10 mH and supports a maximum rated current of 450 mA. The component has a typical DC resistance of 1.75 Ohms and operates within an ambient temperature range of -40°C to +125°C, including self-temperature rise. It is rated for 300 V AC and utilizes a horizontal through-hole mounting configuration with four pins.

Feature Summary

Current-compensated U-core design for effective common mode noise suppression
Suitable for power line filtering applications
Horizontal through-hole mounting for PCB integration

Applications

Power supply input filtering
EMI suppression in electronic equipment
Signal integrity protection in data lines

Procurement Notes

Verify the specific inductance value and current rating against the official EPCOS/TDK datasheet before procurement. Confirm that the horizontal package dimensions and pin spacing match the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a 10 mH common mode choke is required for low-current power lines up to 450 mA. The horizontal form factor is suitable for space-constrained boards requiring low profile. Verify that the 1.75 Ohm DC resistance does not cause excessive voltage drop in the application circuit. Ensure the 300 V AC rating aligns with the system's electrical isolation requirements.

Part Context

This component belongs to the B82730G series of common mode chokes from EPCOS (TDK Electronics). The series offers various inductance values and current ratings tailored for different power line filtering needs. These chokes are widely used in industrial and consumer electronics to mitigate electromagnetic interference on AC and DC power inputs.

Replacement Considerations

Consult the official TDK replacement guide for verified substitutes. Ensure any alternative maintains the same inductance, current rating, and package type.
