Overview
The TDK MMZ1608S181ATA00 is a surface-mount ferrite chip bead designed for signal line applications. It features an impedance of 180 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 500 mA and has a maximum DC resistance of 200 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height, conforming to the 0603 (1608 metric) package standard.
Feature Summary
- Multi-layer construction for compact signal line filtering
- High current handling capability up to 500 mA
- Wide operating temperature range from -55°C to +125°C
Applications
- Signal line noise suppression
- Electromagnetic interference (EMI) filtering in electronic circuits
Procurement Notes
Verify the specific suffix 'ATA00' against official TDK documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor lists to validate authenticity and sourcing channels before procurement.
Selection Notes
Select this component when a 0603 footprint is required for signal integrity management. The 180 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. Verify that the 500 mA current rating exceeds the maximum DC load current of the circuit to prevent saturation or excessive heating during operation.
Part Context
This component belongs to the TDK MMZ series of ferrite beads. The series offers various impedance values and current ratings within standardized metric packages. The MMZ1608S181ATA00 specifically utilizes the 1608 metric case size, providing a balance between electrical performance and board space efficiency for consumer and industrial electronics.
