7427051

Overview

The Würth Elektronik 7427051 is a multi-aperture EMI suppression core belonging to the WE-RIB series. It features a round NiZn ferrite body with an internal diameter of 4 mm and external dimensions of 13.5 mm length, 7 mm width, and 7.5 mm height. The component provides an impedance of 154 Ohms at 100 MHz for single-wire applications and 122 Ohms for double-wire configurations. It operates within a temperature range of -40°C to +90°C.

Feature Summary

• Multi-aperture design for enhanced electromagnetic interference suppression
• NiZn ferrite material construction for high-frequency performance
• Round cable core shape suitable for various wire gauges

Applications

• Electromagnetic interference suppression on cables
• Signal integrity enhancement in digital circuits
• Common mode noise reduction in data lines

Procurement Notes

Verify the specific impedance requirements against the datasheet values of 154 Ohms (single wire) and 122 Ohms (double wire) at 100 MHz. Confirm that the 4 mm internal diameter accommodates the target cable bundle. Ensure compliance with RoHS standards if required by the end application specifications.

Selection Notes

Select this component when multi-aperture geometry is necessary for superior attenuation compared to standard single-hole cores. The NiZn material offers optimal performance for higher frequency noise suppression. Consider the physical constraints of the 13.5 x 7 x 7.5 mm package during PCB or chassis layout planning.
