Procurement Notes
Verify the complete part number including suffixes against official TDK documentation to ensure correct impedance and tolerance specifications. Confirm that the required operating temperature range aligns with the specified +125°C limit. Ensure compatibility with standard reflow soldering profiles for the 1812 package type during assembly planning.
Selection Notes
Select this component when designing for automotive CAN-BUS interfaces requiring specific 22 µH inductance and 1.2 kΩ impedance characteristics. Consider the 200 mA current rating to ensure adequate headroom for signal line operations. Verify that the 1812 package dimensions fit within the designated board layout constraints.
Part Context
This component belongs to the TDK ACT series of automotive-grade common mode chokes. These devices are engineered to meet stringent AEC-Q200 reliability standards for use in harsh automotive environments. The series provides various impedance and inductance options tailored for different automotive bus protocols.
Replacement Considerations
Consult official TDK substitution guides for verified equivalents. Cross-reference impedance values at 10 MHz and inductance ratings to ensure functional compatibility without altering circuit performance.
