• Designed for surface-mount integration into compact electronic circuits
• Capable of handling continuous direct current loads up to specified ratings

Applications

• Signal line filtering in portable electronics
• Power supply noise reduction in consumer devices
• EMI suppression on data transmission lines

Procurement Notes

Verify the manufacturer part number against official Meritek documentation to ensure authenticity. Confirm that the received components match the specified 0805 package dimensions and electrical parameters. Check for physical damage or contamination before soldering. Ensure storage conditions comply with moisture sensitivity levels if applicable.

Selection Notes

Select this component when circuit design requires EMI filtering with a 120 Ohm impedance target at 100 MHz. Ensure the application current does not exceed the 2 Ampere rating to prevent thermal issues. Verify that the 0805 footprint aligns with the printed circuit board layout constraints.

Part Context

Meritek produces passive components including ferrite beads for circuit protection. This model belongs to their series of surface-mount filters designed to attenuate high-frequency noise.
