Overview
The MMZ1005Y301CT000 is a single-line ferrite chip bead from the TDK MMZ series, designed for surface-mount assembly in the 0402 (1005 metric) package. It provides an impedance of 300 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 250 mA and exhibits a maximum DC resistance of 380 mOhms. It operates within a temperature range of -55°C to +125°C and measures 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height.
Feature Summary
- Provides high-impedance signal line filtering for electromagnetic interference suppression
- Engineered for compact surface-mount integration in space-constrained designs
- Maintains stable electrical characteristics across a wide industrial temperature range
Applications
- Signal line noise suppression in portable electronic devices
- EMI filtering for high-speed digital circuits
- Power supply input/output decoupling in compact modules
Procurement Notes
Verify the specific suffix CT000 against the manufacturer's latest documentation to confirm packaging type and tape-and-reel specifications. Ensure the procurement channel sources genuine TDK components to guarantee compliance with RoHS directives and operational reliability standards defined in the official datasheet.
Selection Notes
Select this component when a 0402 footprint is required for signal integrity management. The 300 Ohm impedance rating targets specific noise frequencies around 100 MHz. Verify that the circuit's steady-state current remains below the 250 mA limit to prevent saturation and ensure the thermal environment stays within the specified operating range.
Part Context
This part belongs to the MMZ series of ferrite beads, which are widely used for EMI suppression in consumer electronics and industrial equipment. The MMZ series offers various impedance values and current ratings within standard metric packages, allowing designers to balance size constraints with filtering performance requirements effectively.
Replacement Considerations
MMZ1005Y301C is listed as a previous part number revision for this component. Verify compatibility with updated manufacturing processes before substitution.
