ELK-EV112FC

Overview

The Panasonic ELK-EV112FC is a surface-mount EMI filter designed for digital noise suppression. It integrates a ferrite bead with an internal varistor to provide combined electromagnetic interference filtering and electrostatic discharge protection. The component utilizes a coil-type structure within a 1207 (3218 metric) package, measuring 3.2 mm in length, 1.8 mm in width, and 2.2 mm in height. It features a maximum DC current rating of 2 A and operates within a temperature range of -20°C to +85°C. Key electrical specifications include a cutoff frequency of 8 MHz, a typical inner capacitance of 1050 pF, and a rated voltage of 12 V.

Feature Summary

• Integrates ferrite bead and varistor for simultaneous EMI filtering and ESD protection
• Coil-type construction for effective digital noise suppression
• Surface-mount design suitable for automated assembly

Applications

• Data lines for mobile devices
• HMI and display projects
• General-purpose digital noise filtering

Procurement Notes

Verify the lifecycle status before procurement as the component may be classified as discontinued or last-time buy. Confirm RoHS compliance requirements against specific project standards. Ensure the 1207 package dimensions align with PCB footprint constraints. Validate that the 2 A current rating meets circuit demands. Check for authorized distribution channels due to potential supply limitations.

Selection Notes

Select this component when integrated EMI and ESD protection is required on low-voltage data lines. The 1207 package offers a compact solution for space-constrained designs. Consider the 1050 pF capacitance and 8 MHz cutoff frequency for appropriate signal integrity. Ensure the operating temperature range suits the environmental conditions. Verify compatibility with surface-mount assembly processes.
