ELK-EA103FA

Overview

The Panasonic ELK-EA103FA is a surface-mount EMI filter component classified as a ferrite bead with integrated capacitance. It operates within a temperature range of -20°C to +85°C and supports a maximum DC current of 5 A. The device features a rated voltage of 50 V and a cutoff frequency of 0.5 MHz at DC. Its typical inner capacitance is 10,000 pF (10 nF). The physical dimensions are 3.2 mm in length, 1.8 mm in width, and 2.2 mm in height, conforming to the 1207 package style.

Feature Summary

• Integrates ferrite bead impedance with high capacitance for combined noise suppression and filtering.

Applications

• Data lines for mobile devices

Procurement Notes

Verify availability status carefully as this part may be discontinued or subject to restricted supply conditions. Confirm that the specific order suffix matches the required packaging format, such as cut tape or reel, as these do not alter the electrical function but affect handling. Ensure the procurement channel provides valid traceability documentation for this electronic component.

Selection Notes

Select this component when designing circuits requiring simultaneous attenuation of high-frequency noise and energy storage via capacitance. The 5 A current rating suits power-sensitive applications, while the 1207 footprint allows for compact board layouts. Verify that the operating environment remains within the specified -20°C to +85°C thermal limits for reliable performance.
