Overview
The ACM2012-222-2P-T001 is a surface-mount common mode choke manufactured by TDK Corporation. It features a compact 0805 (2.0mm x 1.2mm) footprint with a maximum height of 1.3mm. The component provides an impedance of 2200 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 150 mA. It has a maximum DC resistance of 2.5 Ohms and a rated DC voltage of 50V. The device operates within a temperature range of -40°C to +105°C and complies with AEC-Q200 standards.
Feature Summary
- Designed for noise suppression in high-speed differential signal lines and general signal lines.
- Constructed with a multilayer chip architecture for reliable surface-mount integration.
- Complies with AEC-Q200 automotive electronic component qualification standards.
Applications
- Noise suppression in high-speed data transmission interfaces
- Signal line filtering in portable electronic devices
- EMI reduction in automotive infotainment systems
Procurement Notes
Verify the complete part number including the suffix to ensure correct impedance and current ratings. Confirm RoHS compliance status and packaging specifications such as reel quantity against the official manufacturer datasheet prior to ordering. Ensure storage conditions align with moisture sensitivity level requirements specified in the product documentation.
Selection Notes
Select this component when space-constrained designs require effective common mode noise attenuation at 100 MHz. The 150 mA current rating suits low-power signal lines rather than power delivery paths. Verify that the 2.5 Ohm DC resistance does not impact signal integrity or voltage drop requirements in the specific circuit application.
Part Context
This component belongs to the TDK ACM series of multilayer common mode chokes. These filters are engineered for use in digital circuits where electromagnetic interference must be minimized without distorting the desired differential signals. The series offers various impedance values to match different frequency noise profiles.
Replacement Considerations
Cross-reference with other TDK ACM2012 series variants such as ACM2012-900-2P-T001 for lower impedance needs. Verify pin compatibility and physical dimensions before substituting with components from other manufacturers to ensure board layout compatibility.
