Overview
The MPZ1005S121ET000 is a ferrite chip bead from the TDK MPZ series, designed for surface mount technology in a 0402 (1005 metric) package measuring 1.0 mm by 0.5 mm. It provides an impedance of 120 ohms at 1 GHz with a tolerance of ±40%. The component supports a maximum DC current of 400 mA and features a maximum DC resistance of 95 milliohms. It operates within a temperature range of -55°C to +125°C and is rated for a maximum voltage of 1.5 V.
Feature Summary
- Engineered for wide-band power line applications requiring high impedance characteristics
- Compact 0402 surface mount footprint suitable for space-constrained designs
- Low DC resistance to minimize power loss in power supply circuits
Applications
- Power line filtering in portable electronic devices
- EMI suppression in compact consumer electronics
- Signal integrity management in high-density PCB layouts
Procurement Notes
Verify the specific suffix ET000 against official TDK documentation to confirm tape and reel packaging specifications. Ensure the selected variant matches the required impedance tolerance and current rating for your circuit design. Cross-reference the datasheet revision date to guarantee compliance with current manufacturing standards and material compositions.
Selection Notes
Select this component when a low-profile 0402 ferrite bead is required for power line noise suppression. The 120-ohm impedance at 1 GHz targets high-frequency interference common in digital circuits. Consider the 400 mA current rating to ensure the component does not saturate under normal operating loads while maintaining effective attenuation.
Part Context
This part belongs to the TDK MPZ series of ferrite beads, which are specialized for power line applications. The series offers various impedance values and current ratings within standard metric packages. The MPZ1005S121ET000 specifically addresses the need for compact EMI suppression in modern miniaturized electronics where space is limited.
Replacement Considerations
Consult TDK's official substitution guide for equivalent parts within the MPZ or MMZ series. Verify that any alternative maintains the same 0402 footprint, 120-ohm impedance, and 400 mA current handling capability to ensure mechanical and electrical compatibility.
