Overview
The TDK ACT45C-510-2P-TL000 is a two-channel surface-mount common mode choke designed for automotive signal lines. It features an inductance of 51 µH and an impedance of 2.8 kOhms at 100 kHz. The component supports a maximum DC current of 200 mA with a maximum DC resistance of 1 Ohm. 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
- Designed specifically for CAN-BUS signal line protection
- Compact 1812 surface-mount footprint for space-constrained PCBs
Applications
- CAN-BUS network filtering in automotive electronics
- Automotive signal line EMI suppression
- On-board communication system noise reduction
Procurement Notes
Verify the specific suffix TL000 against the manufacturer's latest datasheet to confirm pinout and packaging configuration. Ensure the selected variant meets the required AEC-Q200 reliability standards for your specific automotive application environment. Cross-reference the impedance and current ratings with your circuit design requirements before finalizing procurement.
Selection Notes
Select this component when designing for CAN-BUS applications requiring 51 µH inductance and 200 mA current handling. The 1812 package size is suitable for standard automotive PCB layouts. Verify that the 125°C maximum operating temperature aligns with the thermal profile of the target installation area. Consider the 2.8 kOhms impedance at 100 kHz for appropriate noise attenuation characteristics.
Part Context
This part belongs to the TDK ACT series of common mode filters, which are engineered for vehicular devices requiring high-temperature stability. The series includes variants optimized for different automotive protocols such as FlexRay and Ethernet. The ACT45C designation indicates a specific impedance and inductance profile tailored for CAN-BUS systems, distinguishing it from other series members like the ACT45R or ACT1210.
Replacement Considerations
Direct substitutes must match the 51 µH inductance, 200 mA current rating, and 1812 package dimensions. Verify compatibility with CAN-BUS specifications and AEC-Q200 certification. Alternative parts from other manufacturers should offer equivalent impedance curves and thermal performance.
