Overview
The MMZ1005S800HTD25 is a ferrite chip bead from the TDK MMZ-H series, designed for general signal line applications. It features an impedance of 80 Ohms with a 25% tolerance, measured at a test frequency of 100 MHz. The component supports a maximum DC current of 800 mA and has a maximum DC resistance of 100 mOhms. Housed in a compact 0402 (1005 metric) SMD/SMT package measuring 1 mm x 0.5 mm x 0.5 mm, it operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides effective noise suppression for general signal lines through high-impedance characteristics at target frequencies.
- Supports high-current operation up to 800 mA with low DC resistance to minimize signal loss.
- Utilizes a compact 0402 surface-mount footprint suitable for space-constrained PCB layouts.
Applications
- General signal line noise suppression
- High-speed digital circuit filtering
- Power supply input/output decoupling
Procurement Notes
Verify the specific suffix HTD25 against official TDK documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure compatibility with standard reflow soldering profiles for 0402 components. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a 0402 ferrite bead is required for signal integrity management with an 80 Ohm impedance profile. Consider the 800 mA current rating to ensure the component does not saturate under operating conditions. Verify that the 100 mOhm DC resistance meets the voltage drop requirements of the specific circuit design.
Part Context
This part belongs to the TDK MMZ-H series of ferrite chip beads. The series is characterized by its suitability for general-purpose electronic equipment and signal processing applications. The MMZ1005 designation indicates the 1005 metric (0402 inch) case size, which is a standard industry dimension for passive components requiring minimal board area.
Replacement Considerations
The MMZ1005S800HT000 is a related variant within the same series offering identical electrical parameters but potentially different packaging or termination specifications. Verify package compatibility and lead availability before substitution.
