The Fair-Rite 2512061018Y0 is a multilayer ferrite chip bead designed for surface-mount applications. It operates within the 25 series and utilizes a 1206 (3216 metric) package with SMD/SMT termination. The component provides an impedance of 100 Ohms at a test frequency of 25 MHz, with a tolerance of 25%. It supports a maximum DC current of 400 mA and features a maximum DC resistance of 200 mOhms. The device functions reliably across a temperature range from -55°C to +125°C.
Verify the specific impedance tolerance and DC current ratings against the official Fair-Rite datasheet before integration. Confirm that the 1206 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the RoHS status with current regulatory standards for the destination market.
Select this component when space constraints require a 1206 form factor for EMI mitigation. Choose based on the required 100 Ohm impedance profile at 25 MHz for effective noise attenuation. Consider the 400 mA current handling capability to prevent saturation during normal operation. Evaluate the unshielded nature if magnetic coupling with nearby components is a concern.
This part belongs to the Fair-Rite 25 series of multilayer ferrite beads. These components are engineered for high-density PCB layouts where traditional through-hole beads cannot fit. The 2512061018Y0 specifically addresses noise issues in digital signal lines and power rails within small form-factor devices.
