B-03-RT

Overview

The KEMET B-03-RT is a signal line ferrite bead designed for through-hole mounting in an axial, split radial bend package. It features a DC resistance of 5 Ohms at 1 MHz and supports a maximum current rating of 5A. The component operates within a temperature range of -20°C to 70°C. Its physical dimensions include a length of 8.5mm and a width of 2.4mm. This device is RoHS compliant and intended for noise suppression in electronic circuits.

Feature Summary

• Provides signal line noise suppression with a 5 Ohm impedance characteristic at 1 MHz
• Supports high current handling up to 5A for power line applications
• Utilizes a split radial bend form factor for secure through-hole PCB integration

Applications

• Noise filtering in signal lines requiring low impedance characteristics
• Power supply input stages for high-current noise attenuation
• Electromagnetic interference (EMI) suppression in industrial control systems

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official KEMET datasheet prior to procurement. Confirm that the operating temperature range of -20°C to 70°C aligns with the target application environment. Ensure the through-hole mounting style matches the PCB design requirements. Check for RoHS compliance status if restricted substances are a concern for the final product assembly.

Selection Notes

Select this component when a through-hole ferrite bead with a 5A current rating is required. The 5 Ohm impedance at 1 MHz makes it suitable for general-purpose noise suppression. Consider the split radial bend package for mechanical stability during insertion. Evaluate the -20°C to 70°C operating range against environmental conditions. Compare against surface-mount alternatives if space constraints dictate a different form factor.

Part Context

The B-03-RT belongs to KEMET's BEAD L series of ferrite beads. These components are engineered for robust noise suppression in various electronic assemblies. The series offers reliable performance for signal integrity maintenance. KEMET manufactures these devices to meet industry standards for passive components. The part is widely used in applications requiring durable through-hole filtering solutions.

Replacement Considerations

Consult KEMET documentation for direct substitutes within the BEAD L series. Verify that any alternative maintains the 5A current rating and 5 Ohm impedance specification. Ensure the replacement supports the same through-hole mounting style. Confirm compatibility with the -20°C to 70°C operating temperature range.
