MCZ1210AH301CPTD25 is listed in the Common Mode Chokes range at ChipApex. The manufacturer field lists TDK Corporation. Its product description is CMC 100MA 2LN 300OHM SMD AECQ200. Review the specifications below when checking this part for your BOM.
The MCZ1210AH301CPTD25 is a multilayer common mode filter manufactured by TDK Corporation, designed for surface mount technology. It operates within an impedance range of 300 ohms with a tolerance of 25 percent and supports a maximum DC current of 100 mA. The component features a maximum DC resistance of 4.5 ohms and functions reliably across a temperature spectrum from -40°C to +105°C. Housed in a compact 0404 (1210 metric) package measuring 1.25 mm in length, it meets AEC-Q200 automotive standards.
Verify the complete part number including suffixes against official manufacturer documentation to ensure correct impedance, current rating, and packaging specifications. Confirm that the specific variant matches the required operating temperature range and automotive grade certification before procurement. Cross-reference datasheet parameters with design requirements to avoid mismatches in electrical characteristics or physical dimensions.
Select this component when designing circuits requiring common mode noise attenuation for low-current signal lines in automotive environments. Ensure the selected impedance value aligns with the target frequency range for interference suppression. Verify that the maximum DC current rating exceeds the operational current of the protected line to prevent saturation. Consider the thermal performance limits relative to the expected ambient conditions in the installation area.
This component belongs to the MCZ-AH series of multilayer common mode chokes produced by TDK. The series is engineered specifically for automotive electronics applications, offering robust performance under varying environmental conditions. These filters are integral to maintaining signal integrity in sensitive vehicle systems by mitigating electromagnetic interference.
Public confirmed substitute part numbers: None identified.
