ELK-EV150FF

Overview

The ELK-EV150FF is a Coil Type EMI Digital Noise Filter with Varistor manufactured by Panasonic Industry. It utilizes an LC-T circuit topology to provide electromagnetic interference suppression and electrostatic discharge protection for digital data lines. The component operates within a temperature range of -20°C to +85°C and supports a maximum DC current of 2 A. It is housed in a compact 1207 (3218 metric) surface-mount package, measuring 3.2 mm in length, 1.8 mm in width, and 2.2 mm in height.

Feature Summary

• Integrates varistor functionality for combined EMI filtering and ESD protection
• Utilizes LC-T circuit topology for low-pass signal conditioning
• Designed for high-speed digital data line noise suppression

Applications

• Data lines for mobile devices
• High-speed digital interface circuits requiring ESD protection
• Electronics subject to electromagnetic interference in automotive or industrial environments

Procurement Notes

Verify the specific suffix FF against official Panasonic documentation to confirm exact specifications, as ordering suffixes may denote variations in packaging or performance characteristics. Confirm availability status, as this component is listed as End-of-Life or restricted supply in certain distributor channels. Ensure compatibility with existing PCB footprints and thermal management requirements during integration planning.

Selection Notes

Select this component when simultaneous EMI attenuation and ESD protection are required on a single channel. The 2 A current rating suits moderate power applications, while the 1207 package offers a balance between footprint size and electrical performance. Evaluate the 15 pF capacitance value to ensure it meets the bandwidth requirements of the target digital signal without excessive distortion.

Part Context

This part belongs to the ELK-EV series, which focuses on EMI filters and ESD protection solutions. The series includes various configurations tailored for different data rates and current loads. The ELK-EV150FF specifically targets applications needing robust noise filtering in compact form factors, serving as a critical passive component in modern electronic device design.

Replacement Considerations

Consult official Panasonic substitution guides for verified alternatives. Cross-reference parameters such as impedance curves, capacitance values, and current ratings when evaluating potential substitutes from other manufacturers to ensure functional equivalence.
