B82799C334N1

Overview

The B82799C334N1 is a surface-mount common mode choke manufactured by EPCOS, now part of TDK Electronics. It features an inductance of 330 µH and a rated current of 200 mA. Designed for two-line applications, this component utilizes a shielded core structure to minimize electromagnetic interference. The device is qualified under the AEC-Q200 standard, ensuring reliability for automotive environments. It operates within a temperature range of -55°C to +150°C and is housed in a compact SMD package suitable for automated assembly processes.

Feature Summary

• AEC-Q200 qualified for automotive reliability
• Shielded core design for effective noise suppression
• High operating temperature capability up to 150°C

Applications

• Automotive data bus line filtering
• In-vehicle network interface protection
• Common mode noise suppression in electronic control units

Procurement Notes

Verify the specific suffix 'N1' against the official TDK/B82799 series datasheet to confirm exact physical dimensions and termination plating specifications. Ensure the procurement source provides valid AEC-Q200 certification documentation. Cross-reference the manufacturer's latest naming conventions, as EPCOS branding has transitioned to TDK Electronics globally.

Selection Notes

Select this component when designing circuits requiring robust common mode rejection in space-constrained automotive modules. The 200 mA rating dictates suitability for low-current signal lines rather than power distribution. Evaluate the 330 µH inductance value against the target frequency spectrum of the noise to be suppressed. Confirm compatibility with reflow soldering profiles specified in the manufacturing guidelines.

Part Context

This component belongs to the B82799 series of surface-mount common mode chokes from TDK Electronics (formerly EPCOS). The series is engineered specifically for automotive electronics, adhering to strict quality standards required by the industry. These components are integral to maintaining signal integrity in vehicle communication networks by attenuating high-frequency interference.

Replacement Considerations

Consult the official TDK cross-reference list for verified substitutes. Potential alternatives may include other parts within the B82799 family with differing inductance or current ratings, provided they meet the same AEC-Q200 qualification and physical footprint requirements.
