Overview
The CM01U161T is a surface-mount common mode choke manufactured by Taiyo Yuden. It features two lines with an inductance of 160 ohms at the specified frequency and a rated current of 260 mA. The component operates within a temperature range of -40°C to +125°C and has a maximum DC resistance of 600 mOhms. Packaged in a horizontal SMD configuration with four pads, it is designed for high-frequency noise suppression in compact electronic circuits.
Feature Summary
- Dual-line common mode filtering architecture
- Compact horizontal surface-mount footprint
- High-temperature operational stability
Applications
- High-frequency circuit noise suppression
- Wireless device signal integrity protection
- IoT device power line filtering
Procurement Notes
Verify the specific datasheet version for exact impedance curves and thermal derating characteristics. Confirm package orientation matches the PCB silkscreen, as horizontal mounting requires precise pad alignment. Ensure the 260 mA rating meets the continuous current requirements of the target application without exceeding thermal limits.
Selection Notes
Select this component when space-constrained designs require dual-line common mode filtering. The 160 ohm impedance provides effective attenuation for specific noise frequencies. Verify that the 600 mOhms DC resistance does not introduce excessive voltage drop in low-voltage supply lines compared to alternative chokes with lower resistance values.
Part Context
Taiyo Yuden produces a wide range of passive components, including MLCCs and inductors. The CM01U161T belongs to their common mode choke lineup, targeting miniaturization needs in mobile and IoT electronics. This part supports the manufacturer's focus on small-form-factor solutions for modern consumer devices.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternatives based on matching 160 ohm impedance, 260 mA current rating, and compatible 1616 metric or similar SMD package dimensions.
