CIM21K252NE

Chip Ferrite Bead Overview

The CIM21K252NE is a single-line ferrite bead from Samsung Electro-Mechanics, housed in an 0805 (2012 Metric) surface-mount package. It exhibits an impedance of 2.5 kOhms at 100 MHz with a maximum DC resistance of 800 mOhm and a rated current of 250 mA. The component operates within a temperature range of -55°C to 125°C and measures 2.00mm x 1.25mm x 1.10mm.

Chip Ferrite Bead Feature Summary

• Provides high-impedance noise suppression for power lines in the 100 MHz frequency range.
• Designed for compact surface-mount integration using standard 0805 footprints.
• Constructed for reliable operation across wide industrial temperature extremes.

Chip Ferrite Bead Applications

• Power line filtering in portable electronic devices
• Noise suppression in automotive infotainment systems
• EMI reduction in industrial control circuitry

Chip Ferrite Bead Procurement Notes

Verify end-of-life status through official manufacturer channels before design finalization. Confirm RoHS3 compliance and moisture sensitivity level requirements against specific project standards. Ensure supply chain stability given the component's discontinued status by validating authorized distributor availability and lead times.

Chip Ferrite Bead Selection Notes

Select this component when a 2.5 kOhm impedance at 100 MHz is required for a 0805 footprint. Evaluate the 250 mA current rating against peak load conditions to prevent saturation. Consider the 800 mOhm DCR impact on voltage drop in low-voltage power distribution networks.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the CIM21 series, designed for general-purpose EMI suppression. It complements Samsung Electro-Mechanics' passive filter portfolio, offering a balance between size constraints and attenuation performance for modern miniaturized electronics.

Chip Ferrite Bead Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Designers should evaluate equivalent impedance characteristics from other manufacturers if sourcing becomes unavailable.

Chip Ferrite Bead FAQ

What is the impedance value of the CIM21K252NE?

The impedance is 2.5 kOhms measured at 100 MHz.

Is the CIM21K252NE suitable for high-current applications?

No, it has a rated current of 250 mA, making it suitable for low-power signal or power line filtering rather than high-current loads.
