Overview
The ACT45C-110-2P-TL000 is a two-channel surface-mount common mode choke filter manufactured by TDK. It features an inductance of 11 µH and a common mode impedance of 600 Ω at 10 MHz. The component supports a maximum DC current of 250 mA with a maximum DC resistance of 600 mΩ. Designed for automotive applications, it holds AEC-Q200 qualification and operates within a temperature range of -40°C to +125°C. The device utilizes a 1812 (4532 metric) package measuring 4.5 mm x 3.2 mm x 2.8 mm.
Feature Summary
- AEC-Q200 qualified for automotive signal line reliability
- Compact 1812 surface-mount footprint for space-constrained designs
- High common mode impedance for effective EMI suppression
Applications
- CAN-BUS signal line filtering
- Automotive electronic control unit protection
- EMI suppression in vehicle communication networks
Procurement Notes
Verify the specific suffix TL000 against the official TDK datasheet to confirm packaging type and tape/reel specifications. Ensure the ordering part number matches the required impedance and current ratings for the target circuit. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory for the final assembly.
Selection Notes
Select this component when designing for CAN-BUS interfaces requiring moderate inductance and low DC resistance. The 250 mA rating suits low-power signal lines rather than high-current power distribution. Consider the 1812 package size for PCB layout constraints and verify thermal performance within the specified -40°C to +125°C operating range.
Part Context
This part belongs to the TDK ACT series of automotive-grade common mode chokes. The series provides various impedance and inductance combinations tailored for different automotive bus protocols. The ACT45C variant specifically targets CAN-BUS applications, distinguishing it from FlexRay or LIN variants within the same product family.
Replacement Considerations
Consult TDK documentation for direct cross-references. Other ACT series parts may offer different impedance levels but require verification of pin compatibility and electrical parameters.
