2512061218Y0A4

Overview

The Fair-Rite 2512061218Y0A4 is a multilayer ferrite chip bead designed for surface mount applications. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 450 mA and has a maximum DC resistance of 200 mOhms. Operating temperatures range from -55 C to +125 C.

Feature Summary

• Multilayer construction for high-density surface mount integration
• Unshielded design suitable for general EMI suppression
• Snap-in termination style for reliable SMD/SMT soldering

Applications

• High-frequency noise suppression in portable electronics
• Signal line filtering in consumer devices
• Power rail decoupling in compact circuit boards

Procurement Notes

Verify the specific suffix 'A4' against manufacturer documentation to confirm tape and reel specifications. Confirm RoHS compliance status directly with Fair-Rite as datasheet details may vary by revision. Ensure the 1206 footprint matches PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a 1206 footprint is required for space-constrained designs. The 450 mA current rating suits low-power signal lines rather than high-current power paths. Verify that the 120 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum for effective attenuation.

Part Context

This part belongs to the Fair-Rite 25 series of multilayer ferrite chip beads. These components are engineered for integrated circuit protection and data line filtering. The series offers various impedance values within the standard 1206 package form factor to accommodate different circuit requirements.

Replacement Considerations

The 2512061217Y0 is a parameter-equivalent alternative offering identical 120 Ohm impedance and 1206 package dimensions. Both parts share similar electrical characteristics and mounting profiles.
