Overview
The TDK ACT45C-101-2P-TL000 is a two-channel surface-mount common mode choke designed for automotive signal lines. It features an inductance of 100 µH at 100 kHz and provides high impedance, specified as 5000 ohms or 5.8 kOhms depending on the test frequency (10 MHz). The component supports a maximum DC current of 150 mA with a maximum DC resistance of 2 Ohms. It operates within a temperature range of -40°C to +125°C and holds AEC-Q200 qualification. The device is housed in a compact 1812 (4.5 mm x 3.2 mm x 2.8 mm) package.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- High impedance performance for effective noise suppression
- Compact 1812 surface-mount footprint
Applications
- CAN-BUS signal line filtering
- Automotive electronic control unit protection
- Automotive signal line interference suppression
Procurement Notes
Verify the specific impedance rating against your design requirements, as sources cite both 5000 ohms and 5.8 kOhms at different frequencies. Confirm the operating temperature limit is sufficient for your application, noting the standard 125°C rating. Ensure the 150 mA current handling meets circuit demands. Check for RoHS compliance details if required by your manufacturing process.
Selection Notes
Select this component when designing for CAN-BUS applications requiring robust common mode noise rejection in a small form factor. The 100 µH inductance offers strong attenuation characteristics. Consider the 2 Ohm DCR impact on signal integrity. The AEC-Q200 certification makes it suitable for strict automotive environments where long-term stability under thermal stress is critical.
Part Context
This part belongs to the TDK ACT series of automotive-grade common mode chokes. These components are engineered specifically for protecting sensitive data lines in vehicles. The ACT45C variant utilizes advanced materials to achieve high performance in a standardized 1812 package, balancing size constraints with electrical efficiency for modern automotive electronics.
Replacement Considerations
Check for other parts within the ACT45C series with similar inductance values. Verify that any substitute maintains the same AEC-Q200 qualification and physical dimensions. Ensure the replacement's current rating and impedance profile match the original specifications for the target bus protocol.
