Overview
The ACM3225-271-2P-T001 is a two-line common mode choke manufactured by TDK Corporation, designed for surface mount applications. It features an impedance of 270 Ohms at 100 MHz and supports a rated current of 300 mA with a maximum DC resistance of 300 milliohms. The component operates within a temperature range of -25°C to 85°C and has a maximum rated voltage of 20 V DC. Its physical dimensions are 3.20 mm in length, 2.50 mm in width, and a maximum height of 2.30 mm.
Feature Summary
- Provides effective suppression of common mode noise in high-speed signal lines through dual-line configuration.
- Offers low insertion loss due to minimal DC resistance, preserving signal integrity.
- Utilizes a compact molded surface mount package suitable for space-constrained designs.
Applications
- High-speed data transmission interfaces
- USB and HDMI signal line protection
- Portable electronic devices requiring EMI mitigation
Procurement Notes
Verify the specific suffix T001 to confirm tape and reel packaging requirements. Confirm that the component status is acceptable for new designs, as availability may vary. Ensure compatibility with standard reflow soldering profiles specified in the manufacturer's guidelines.
Selection Notes
Select this component when a 270 Ohm impedance at 100 MHz is required for common mode noise reduction. Ensure the circuit current does not exceed 300 mA to prevent saturation. Verify that the 2.30 mm maximum height fits within the board's mechanical constraints.
Part Context
This part belongs to the ACM series of common mode chokes from TDK. The series offers various impedance and current ratings in standardized surface mount packages. The ACM3225 designation indicates a 3225 metric footprint, commonly referred to as 1210 imperial size.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official replacement guides or contact the manufacturer for qualified alternatives if this component is obsolete or unavailable.
