Overview
The TDK ACM3225-102-2P-T001 is a two-line common mode choke designed for surface mount applications. It features an impedance of 1 kOhms at 100 MHz and supports a rated current of 200 mA. The component has a maximum DC resistance (DCR) of 500 mOhm. It utilizes a 4-lead package with dimensions of 3.20 mm in length, 2.50 mm in width, and a maximum height of 2.30 mm. The device operates within a temperature range of -25°C to 85°C.
Feature Summary
- Provides effective common mode noise suppression for differential signal lines
- Utilizes a compact surface mount footprint for automated assembly
- Constructed with a molded core structure for mechanical stability
Applications
- Noise filtering on high-speed data interfaces such as USB and HDMI
- Signal integrity protection in portable electronic devices
- Common mode interference reduction in automotive infotainment systems
Procurement Notes
Verify the specific impedance tolerance and current rating requirements against the official TDK datasheet before ordering. Confirm that the 500 mOhm DCR specification aligns with your circuit's power loss constraints. Ensure the 3.2x2.5mm package dimensions fit the designated PCB land pattern. Check for RoHS compliance status if required by regional regulations. Validate availability through authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when designing circuits requiring moderate noise attenuation at 100 MHz. The 200 mA current rating suits low-power signal lines rather than high-current power rails. Consider the 500 mOhm DCR impact on signal voltage drop. Compare with higher impedance variants if stronger noise suppression is needed. Evaluate thermal performance within the specified -25°C to 85°C operating range.
Part Context
This part belongs to TDK's ACM series of common mode chokes, which are widely used in consumer electronics and automotive applications. The 3225 metric code indicates a standard small outline package size compatible with most SMD placement equipment. The series offers various impedance and current combinations to suit different signal line requirements.
Replacement Considerations
Direct substitutes include other TDK ACM3225 series parts with similar impedance ratings. Cross-reference with equivalent offerings from manufacturers like Murata or Coilcraft using matching 3225 footprints and 1 kOhm @ 100 MHz specifications. Verify pinout compatibility and electrical parameters before substitution.
