Overview
The ACT45L-201-2P-TL000 is a two-channel common mode choke manufactured by TDK Corporation, designed for signal line applications. It features an inductance of 200 uH and an impedance of 10 kOhms at the specified test frequency. The component supports a maximum DC current of 100 mA with a maximum DC resistance of 4.5 Ohms. Rated for 50V, it operates within a temperature range of -40°C to +105°C. Housed in an unshielded 1812 (4532 metric) surface mount package measuring 4.5 mm x 3.2 mm x 2.8 mm, it meets AEC-Q200 automotive qualification standards.
Feature Summary
- Designed for suppressing electromagnetic interference in automobile signal lines using reflow iron soldering methods.
- AEC-Q200 qualified for automotive reliability requirements.
- Two-channel configuration for differential signal filtering.
Applications
- Automobile signal line filtering
- Electromagnetic interference suppression in electronic circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm that the specific suffix TL000 matches the required reel or cut tape specifications for your assembly process. Ensure compatibility with reflow iron soldering profiles as indicated in the official datasheet. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory for your design.
Selection Notes
Select this component when designing for automotive signal lines requiring high common mode impedance of 10 kOhms. The 100 mA current rating suits low-power signal applications rather than power delivery. The 1812 package size offers a compact footprint for dense PCB layouts. Consider the -40°C to +105°C operating range against your environmental conditions. Verify that the unshielded construction does not interfere with nearby sensitive components.
Part Context
This part belongs to the TDK ACT series of common mode chokes, which are engineered for automotive and industrial applications. The series provides various inductance values and current ratings in standardized surface mount packages. The ACT45L variant specifically targets signal line protection with optimized impedance characteristics for noise reduction in communication buses.
Replacement Considerations
Public documentation suggests ACT1210L-201-2P-TL00 as a suggested alternate. Verify pinout compatibility and electrical parameters before substitution. Note that the ACT45R-101-2P-TL001 shares similar packaging but differs in current rating and impedance characteristics.
