Overview
The MPZ2012S221AT000 is a surface-mount ferrite bead from TDK Corporation, designed for power line filtering applications. It features a multi-layer chip construction with a ferrite core. The component provides an impedance of 220 Ohms at 100 MHz and supports a maximum rated current of 3A. Its DC resistance is specified as a maximum of 40 milliohms. The physical dimensions correspond to the 0805 (2012 Metric) package size, measuring 2.00mm in length, 1.25mm in width, and 0.85mm in thickness.
Feature Summary
- Multi-layer chip construction utilizing ferrite material for effective high-frequency noise suppression.
- Designed specifically for power line filtering to protect sensitive electronic circuits.
- Low DC resistance characteristic minimizes voltage drop and power loss in the circuit path.
Applications
- Power line filtering in consumer electronics
- Noise suppression in industrial equipment
- Signal integrity management in data processing units
Procurement Notes
Verify the specific ordering suffix and packaging configuration against the official TDK datasheet before procurement. Confirm that the required tape and reel quantity matches your production needs. Ensure the component's RoHS compliance status aligns with your assembly regulations. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when a 220 Ohm impedance at 100 MHz is required for power lines. The 3A current rating suits moderate power applications. The 0805 footprint allows for compact PCB layouts. Consider the low DC resistance for efficiency-critical designs. Verify thermal performance requirements against the component's specifications.
Part Context
This ferrite bead belongs to TDK's general-purpose chip bead series. It is engineered for suppressing electromagnetic interference on power supply lines. The multi-layer technology enables high reliability and consistent electrical characteristics. It serves as a standard solution for common mode noise reduction in various electronic assemblies.
Replacement Considerations
MPZ2012S221AT000 is a direct replacement for HF70ACC575018-T in terms of function, though package sizes differ. HI2220R151R-10 is listed as a similar alternative by distributors but has different impedance and package dimensions. Verify compatibility carefully when substituting.
