B82734W2202B030

Overview

The B82734W2202B030 is a current-compensated D-core double choke manufactured by EPCOS (TDK Electronics). It features a nominal inductance of 20 mH and a rated current of 2 A. The component operates within an ambient temperature range of -40 °C to +125 °C and supports a rated voltage of 250 V AC. Designed for horizontal mounting, it utilizes a ferrite core and radial leads. This general-purpose inductor serves as a filter choke, offering electromagnetic interference suppression in electronic circuits without magnetic shielding.

Feature Summary

• Current-compensated design utilizing a D-core ferrite structure for effective noise filtering
• Capable of handling high rated currents with stable performance across wide temperature ranges
• Horizontal mounting configuration suitable for standard through-hole assembly processes

Applications

• Electromagnetic interference (EMI) filtering in power supply circuits
• Noise suppression in industrial control systems
• Signal integrity maintenance in automotive electronics

Procurement Notes

Verify the complete ordering code against official TDK/EPCOS documentation to ensure correct specifications. Confirm that the suffix indicates the intended lead finish and packaging format. Cross-reference the manufacturer's latest datasheet for any updates on compliance status or recommended operating conditions before finalizing procurement orders.

Selection Notes

Select this component when a dual-line common mode choke with 20 mH inductance is required. Ensure the circuit current does not exceed the 2 A rating at the maximum operating temperature. Verify that the physical dimensions accommodate the horizontal mounting style and that the 250 V AC voltage rating meets the system requirements.
