B82614R2272A030

Overview

The B82614R2272A030 is a through-hole power line choke from the EPCOS B82614 series, designed for AC mains applications. It features an air-gapped rectangular ferrite core and a closed polycarbonate coil former rated UL 94 V-0. The component provides 500µH inductance at 100kHz with a maximum current rating of 2.7A and a typical DC resistance of 230mOhm. Rated for 250V AC, it utilizes a four-section winding to achieve high resonance frequency and low saturation effects. The device is RoHS-compatible and suitable for wave soldering.

Feature Summary

• High resonance frequency achieved through specialized four-section winding construction
• Low saturation effects enabled by the use of an air-gapped ferrite core
• Design complies with EN 60938-2 (VDE 0565-2) standards
• Recyclable construction due to the omission of encapsulation and glue

Applications

• Switch-mode power supplies with current pump
• Output filter in switch-mode applications
• Reduction of harmonics and PFC

Procurement Notes

Verify the specific suffix against the official TDK-EPCOS datasheet to confirm exact electrical tolerances and packaging configuration. Ensure the ordering code matches the required inductance value and current rating for the target circuit design. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement.

Selection Notes

Select this component for AC line filtering where high resonance frequency and low saturation are critical. The 2.7A current rating and 250V AC voltage rating suit standard single-phase mains applications. Consider the through-hole mounting type and physical dimensions for PCB layout compatibility. Verify thermal performance under continuous load conditions relative to the +40°C reference temperature specified in the datasheet.

Part Context

This part belongs to the B82614 series of sine-wave chokes manufactured by EPCOS, now part of the TDK Group. The series covers rated currents from 0.8A to 2.7A and inductances from 0.5mH to 3.0mH. These components are engineered for robust performance in power line filtering applications, utilizing ferrite cores and polycarbonate formers to ensure reliability and compliance with international safety standards.

Replacement Considerations

Cross-reference with other B82614 variants such as B82614R2102A030 for different inductance values within the same series. Ensure substitute parts maintain identical mounting types, voltage ratings, and current capabilities. Verify that any alternative component meets the same EN 60938-2 design compliance and RoHS requirements.
