Procurement Notes
Verify the manufacturer part number TCM2010H-900-4P-T000 against official TDK documentation to ensure authenticity. Confirm that the received components match the specified 0504 package dimensions and electrical characteristics. Check for any discrepancies in labeling or packaging that may indicate counterfeit products. Ensure compliance with RoHS directives if required for your application.
Selection Notes
Select this component when designing circuits requiring common mode noise filtering for high-speed signals in small form factors. The 90 Ohm impedance at 100 MHz makes it suitable for specific frequency ranges. Consider the 100 mA current rating and 850 mOhm DCR for power loss calculations. Ensure the 0504 footprint fits within the available board space constraints.
Part Context
This component is part of TDK's TCM series of common mode chokes, which are engineered for signal integrity in modern electronics. The TCM2010H variant specifically targets applications needing compact filtering solutions. The '900' suffix indicates the impedance value, while '4P' denotes the four-line configuration. This series is widely used in consumer electronics and industrial equipment.
Replacement Considerations
When replacing this component, verify that substitute parts offer equivalent impedance at 100 MHz and meet the 100 mA current requirement. Ensure the replacement fits the 0504 (1210 Metric) footprint. Cross-reference with TDK's official substitution guides for compatible alternatives.
