B-03-R

Overview

The KEMET B-03-R is an axial lead ferrite bead designed for normal mode noise suppression in DC line filter applications. It features a 5Ω impedance at 1MHz and supports a maximum current rating of 5A. The component utilizes a split radial bend lead configuration with dimensions of 2.4mm width by 8.5mm length. This device serves as a differential mode choke to attenuate electromagnetic interference in electronic circuits.

Feature Summary

• Provides effective normal mode noise attenuation for signal and power lines
• Features a split radial bend lead configuration for secure PCB mounting
• Engineered specifically for integration into DC line filter assemblies

Applications

• DC line filtering in electronic equipment
• Signal line noise suppression
• Differential mode choke implementation

Procurement Notes

Verify the specific impedance tolerance and current derating curves against your circuit requirements before finalizing the design. Confirm that the axial lead spacing matches your printed circuit board layout constraints. Ensure the operating temperature range aligns with your system's environmental conditions to maintain performance stability.

Selection Notes

Select this component when normal mode noise reduction is required on DC lines carrying up to 5A. The 5Ω impedance value targets specific frequency ranges for interference suppression. Consider the physical footprint and lead style compatibility with your assembly process during the selection phase.

Part Context

This ferrite bead belongs to KEMET's passive component portfolio, focusing on electromagnetic interference mitigation. Ferrite beads function as frequency-dependent resistors, dissipating high-frequency noise energy as heat while allowing DC or low-frequency signals to pass unimpeded.

Replacement Considerations
