B82796S253N201

Overview

The B82796S253N201 is a current-compensated ring core choke manufactured by EPCOS - TDK Electronics. It features a horizontal package with four PC pins and utilizes a bifilar winding configuration on a ferrite core. The component has an inductance of 25 µH and a maximum current rating of 800 mA. It supports AC voltage ratings up to 42 V and DC voltage ratings up to 80 V. The operating temperature range spans from -40°C to +125°C, ensuring reliability across diverse environmental conditions.

Feature Summary

• Current-compensated design utilizing a ferrite ring core for effective interference suppression
• Bifilar winding construction optimized for signal line applications
• Horizontal through-hole mounting format with tinned terminals suitable for standard assembly processes

Applications

• Suppression of asymmetrical and symmetrical interference coupled into data lines
• Signal filtering in telecommunications equipment
• EMC reduction in high-frequency data transmission circuits

Procurement Notes

Verify the specific manufacturer designation, as sourcing records may list AVX or other distributors alongside EPCOS-TDK Electronics. Confirm the physical package style matches the required horizontal through-hole footprint. Ensure the electrical parameters align with the system's voltage and current requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring common-mode noise attenuation for two-wire data lines. The 800 mA current rating and 25 µH inductance make it suitable for moderate-speed signal integrity preservation. Consider the horizontal form factor for board space constraints and the wide temperature range for industrial environments.

Part Context

This component belongs to the B82796 series of data line chokes designed for telecommunications and signal processing applications. It serves as a passive filter element to maintain signal quality by attenuating unwanted electromagnetic interference without distorting the primary data transmission characteristics.

Replacement Considerations

Compatible substitutes within the same family include B82796S0253N201 and B82796S513N201. Verify pin compatibility and electrical specifications before substitution.
