CIS10P300AC

Chip Ferrite Bead Overview

The CIS10P300AC is a ferrite bead from the Samsung Electro-Mechanics CIS10P series, designed for power line noise suppression. It features a single-line configuration in a 0603 (1608 metric) surface-mount package with dimensions of 1.60mm x 0.80mm and a maximum height of 0.95mm. The component exhibits an impedance of 30 Ohms at 100 MHz and supports a maximum current rating of 6A. Its DC resistance (DCR) is limited to a maximum of 10 milliohms. The device operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression on power lines through high-frequency impedance characteristics.
• Supports high-current applications up to 6A with minimal DC voltage drop due to low resistance.
• Utilizes a compact 0603 surface-mount footprint suitable for dense board layouts.

Chip Ferrite Bead Applications

• Power supply input filtering
• Noise suppression on high-current data lines
• EMI reduction in portable electronic devices

Chip Ferrite Bead Procurement Notes

This component is officially obsolete and no longer manufactured by Samsung Electro-Mechanics. Procurement should focus on verified substitute part numbers rather than original stock. Verify that any replacement matches the required impedance, current rating, and physical dimensions to ensure circuit compatibility and reliability.

Chip Ferrite Bead Selection Notes

Selection requires matching the 30 Ohm impedance at 100 MHz and 6A current handling capability. The 0603 package size must fit the design constraints. Since the original part is discontinued, engineers must evaluate alternative ferrite beads from other manufacturers that meet these specific electrical and mechanical parameters for equivalent performance.

Chip Ferrite Bead Part Context

The CIS10P300AC belongs to the CIS10P series of chip beads from Samsung Electro-Mechanics. This series is characterized by high current ratings and low DC resistance, making it suitable for power line applications. The product lifecycle status is End-of-Life, as indicated by public discontinuation notices.
