Overview
The B78512A8286A003 is a surface-mount ring core choke manufactured by EPCOS, now part of TDK Electronics. Classified as a common mode inductor, this component is designed to filter electromagnetic interference within power distribution and signal lines. The device utilizes a ring core structure to effectively suppress common mode noise while maintaining signal integrity. It is RoHS3 compliant and represents an obsolete product status within the manufacturer's current portfolio.
Feature Summary
- Surface-mount ring core construction for compact integration
- Common mode inductor functionality for electromagnetic interference filtering
- Designed for use in power distribution and signal line applications
Applications
- Power distribution systems requiring EMI suppression
- Signal lines needing common mode noise reduction
- Electronic circuits where surface-mount inductors are required
Procurement Notes
Verify component availability carefully as the B78512A8286A003 is listed with an obsolete product status. Confirm RoHS3 compliance requirements against specific project standards. Ensure that any substitute components maintain equivalent inductance and current ratings to preserve circuit performance. Check datasheet specifications for pin compatibility if replacing existing designs.
Selection Notes
Select this component based on its specific ring core geometry and surface-mount form factor. Evaluate its suitability for common mode noise filtering in sensitive signal paths. Consider the obsolete status when planning long-term production runs. Verify electrical parameters such as impedance and saturation current against application requirements before finalizing the design.
Part Context
EPCOS was acquired by TDK Corporation, merging their passive component activities. The B78512 series belongs to the SMD ring core choke family, which provides efficient electromagnetic interference suppression. This specific model falls under the broader category of inductors used in industrial and consumer electronics for noise control.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineering changes may be necessary. Consult official TDK resources for current equivalents or design-in alternatives that match the required electrical characteristics.
