7427927115

Overview

The Würth Elektronik 7427927115 is a multilayer chip ferrite bead from the WE-CBF series, designed for signal line EMI suppression. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.55mm. The component provides an impedance of 150 ohms at 100 MHz and supports a rated current of 100 mA. Its DC resistance is maximized at 400 milliohms. It operates within a temperature range of -55°C to +125°C and complies with AEC-Q200 standards.

Feature Summary

• Multilayer construction for compact signal line filtering
• AEC-Q200 qualified for automotive reliability
• High impedance performance in small 0402 footprint

Applications

• USB 2.0 high-speed data lines
• IEEE 1394 interfaces
• LVDS signal transmission
• RS232 control signals

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for recent Product Change Notifications (PCN) regarding manufacturing site changes. Ensure storage conditions meet moisture sensitivity level requirements before reflow soldering.

Selection Notes

Select this component for applications requiring EMI suppression in tight space constraints where a 0402 package is mandatory. Evaluate the 100 mA current rating against peak load requirements to prevent saturation. Consider the 150 ohm impedance profile for target noise frequencies around 100 MHz.
