78271111

Overview

The Würth Elektronik 78271111 is a snap-on ferrite core from the WE-CAR-TEC series, designed for electromagnetic interference suppression. It features a circular split-core design with an internal diameter of 5.00 mm and requires a key for opening. The component measures 41.10 mm in length, 23.40 mm in width, and 18.00 mm in height. It exhibits an impedance of 316 Ω at 100 MHz and is constructed from NIZn material. Certified to AEC-Q200 standards, it supports free-hanging installation.

Feature Summary

• Snap-on hinged design requiring a key for operation
• AEC-Q200 qualified for automotive reliability
• Free-hanging installation capability

Applications

• General electronic equipment
• Automotive applications
• EMI suppression on cables

Procurement Notes

Verify the specific part number 78271111 against official Wurth Elektronik documentation to confirm current availability and compliance status. Ensure that the requirement for a separate opening key is accounted for in the assembly process. Cross-reference the AEC-Q200 certification details if the application demands strict automotive qualification adherence.

Selection Notes

Select this component when a 5 mm inner diameter is required for cable management. The 316 Ω impedance at 100 MHz suits high-frequency noise reduction. Consider the physical dimensions (41.10 x 23.40 x 18.00 mm) for spatial constraints. The need for a key mechanism distinguishes it from standard push-on cores.

Part Context

This component belongs to the WE-CAR-TEC series, which focuses on snap-on ferrites for automotive and general electronics. It utilizes NIZn material for effective high-frequency performance. The series is characterized by its hinged design, offering convenient installation without cable disconnection.
