Overview
The Eaton MFBW1V3216-181-R is a multilayer chip ferrite bead designed for surface-mount applications. It provides 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 2.5 A and features a low maximum DC resistance of 70 mOhms. Housed in a standard 1206 (3216 metric) package measuring 3.2 mm x 1.6 mm x 0.9 mm, it operates within a temperature range of -40°C to +85°C.
Feature Summary
- Multilayer construction for effective high-frequency noise suppression
- Shielded design to minimize electromagnetic interference coupling
- High current handling capability suitable for power line filtering
Applications
- Power supply output filtering
- DC/DC converter noise attenuation
- Signal line EMI suppression
Procurement Notes
Verify the specific impedance value and current rating against the circuit requirements before ordering. Confirm that the 1206 footprint matches the PCB layout. Ensure the operating temperature range meets the environmental conditions of the target application. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.
Selection Notes
Select this component when a 180 Ohm impedance is required at 100 MHz for noise reduction. The 2.5 A current rating allows use in moderate power circuits. The 1206 package offers a balance between size and thermal performance. Consider the 70 mOhms DC resistance impact on voltage drop if efficiency is critical.
Part Context
This part belongs to the Eaton MFBW1V series of multilayer ferrite beads. These components are engineered for compact electronic designs requiring reliable EMI suppression. The series utilizes advanced ceramic materials to achieve stable impedance characteristics across the specified temperature range.
Replacement Considerations
Direct substitutes include other 1206 ferrite beads with similar 180 Ohm impedance and 2.5 A ratings from manufacturers like TDK or Murata. Verify pin compatibility and impedance curves before substitution.
