Overview
The Ferroxcube WBC2.5/R-4B1-Z is a wideband choke utilizing 4B1 ferrite material, designed for EMI suppression in signal lines. It features an axial package with a bead length of 10 mm and a diameter of 6.3 mm maximum. The component exhibits an impedance magnitude of at least 700 Ohms at 75 MHz and 725 Ohms at 100 MHz. Electrical characteristics include a rated current capacity of 2.5 A and a DC resistance of 400 milliohms. These parameters define its performance in high-frequency noise attenuation applications.
Feature Summary
- Constructs wideband chokes using specific 4B1 ferrite material for effective electromagnetic interference suppression.
- Provides axial mounting configuration suitable for through-hole integration in electronic circuits.
- Designed to attenuate high-frequency noise signals within specified impedance ranges.
Applications
- EMI suppression in single signal lines
- Wideband choke applications requiring axial packaging
- High-frequency noise filtering in electronic assemblies
Procurement Notes
Verify the exact impedance specifications against the official Ferroxcube datasheet for the specific suffix variant. Confirm that the 4B1 material grade matches the required frequency response for your application. Ensure the axial dimensions and current ratings align with your circuit design constraints before finalizing procurement decisions.
Selection Notes
Select this component when axial mounting is required for wideband choking applications. The 4B1 material offers specific permeability characteristics suitable for the targeted frequency range. Consider the 2.5 A current rating and low DC resistance when designing power or signal paths where minimal voltage drop is critical.
Part Context
This part belongs to the WBC2.5/R series of wideband chokes manufactured by Ferroxcube. The series utilizes various ferrite materials, with the 4B1 grade providing distinct impedance profiles. These components are engineered for EMI suppression, differing from standard inductors by their frequency-dependent resistive behavior.
Replacement Considerations
Cross-reference with other Ferroxcube parts in the WBC2.5/R series if different impedance curves are needed. Verify physical footprint compatibility when substituting with similar axial ferrite beads from other manufacturers.
