ACT45B-101-2P-TL003

Overview

The ACT45B-101-2P-TL003 is a surface-mount common mode choke from the TDK ACT45B series, designed for automotive applications. It features two lines with an inductance of 100 µH and a maximum DC resistance of 2 ohms. The component operates within a temperature range of -40°C to +150°C and holds AEC-Q200 qualification. Its impedance is specified at 5.8 kΩ @ 10 MHz, with a rated current of 150 mA and a voltage rating of 50 V.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High operating temperature capability up to 150°C
• Non-dissolution abutment design for secure board mounting

Applications

• CAN-BUS signal line filtering
• Automotive electronic circuit protection
• Industrial signal line noise suppression

Procurement Notes

Verify the specific suffix TL003 against the manufacturer's latest datasheet to confirm packaging and tape specifications. Ensure the component meets the required AEC-Q200 grade for your target application environment. Cross-reference the part number with official TDK documentation to avoid substitution errors with similar series components.

Selection Notes

Select this component when designing circuits requiring robust common mode noise suppression in high-temperature automotive environments. The 100 µH inductance and 150 mA current rating suit low-power signal lines such as CAN bus interfaces. Verify that the 2 ohm DCR aligns with your system's power budget and signal integrity requirements.

Part Context

This part belongs to the ACT45B series of surface-mount common mode chokes manufactured by TDK. The series is engineered specifically for automotive electronics, offering compact dimensions suitable for space-constrained PCB layouts. The LGJ45B series has been discontinued, with the ACT45B series serving as the modern replacement.

Replacement Considerations

The LGJ45B-101-2P-TL003 is the discontinued predecessor. The ACT45B-101-2P-TL003 is the confirmed direct substitute within the same family.
