Procurement Notes

Verify the specific ordering code against official TDK Electronics documentation to ensure exact specification alignment. Confirm package orientation and pin configuration requirements for your PCB layout. Cross-reference technical parameters such as inductance tolerance and thermal ratings with your system design constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring common mode chokes for high-speed data or signal integrity preservation. Ensure the operating environment stays within the specified -40°C to +125°C range. Verify that the 80 V DC and 42 V AC voltage ratings exceed the maximum expected line voltages to prevent dielectric breakdown or performance degradation under load conditions.

Part Context

This component belongs to the EPCOS data and signal line choke series, now produced under the TDK Electronics brand following corporate restructuring. These components are engineered to provide reliable noise suppression in compact form factors suitable for modern electronic assemblies where space efficiency and signal fidelity are critical design priorities.

Replacement Considerations

Consult official TDK Electronics substitution guides for verified equivalent part numbers. Do not assume mechanical or electrical interchangeability with generic chokes without validating pinout, inductance values, and thermal characteristics against the original datasheet specifications.
