7427055

Overview

The Würth Elektronik 7427055 is a multi-aperture EMI suppression core from the WE-RIB series. It features NiZn ferrite material with a round shape and an inner diameter of 4 mm. The component measures 13.5 mm in length, 7 mm in width, and 7.5 mm in height. It provides an impedance of 154 Ohms at 100 MHz for single wire applications and 122 Ohms for double wire configurations. The unit weighs 3.35 g and operates within a temperature range of -40°C to +90°C.

Feature Summary

• Multi-aperture design for enhanced electromagnetic interference suppression
• NiZn ferrite composition optimized for high-frequency noise reduction
• Snap-on installation mechanism for rapid cable integration

Applications

• Single wire EMI suppression
• Double wire EMI suppression
• Cable noise filtering

Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the WE-RIB series specifications, including the 154 Ohm impedance rating at 100 MHz. Check for RoHS compliance markers as indicated in the product data sheet. Ensure the physical dimensions align with the stated 4 mm inner diameter and overall housing size.

Selection Notes

Select this component when a snap-on ferrite solution is required for cables up to 4 mm in diameter. The NiZn material offers effective attenuation in the high-frequency range. Consider the operating temperature limits of -40°C to +90°C for environmental compatibility. The multi-aperture structure allows for efficient noise suppression without requiring cable disconnection.
