FB321611T-152Y-S

Chip Ferrite Bead Overview

The FB321611T-152Y-S is a multilayer ferrite chip bead manufactured by Cal-Chip Electronics, Inc. Designed for surface mount applications, this component provides EMI/RFI attenuation in signal lines. It features a 1206 (3216 Metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The device offers an impedance of 1500 Ohms at 100 MHz and supports a maximum current rating of 350 mA. Its DC resistance is specified at 400 mΩ.

Chip Ferrite Bead Feature Summary

• Multilayer construction utilizing magnetic material for high electrode strength and solder heat resistance
• Designed for direct PCB mounting to eliminate EMI/RFI without requiring additional wiring
• Optimized for flow, reflow, and wave soldering processes required for surface mounting

Chip Ferrite Bead Applications

• High-frequency signal filtering in electronic equipment
• EMI suppression for portable devices
• Noise attenuation in digital circuit signal lines

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and current rating requirements against your circuit design before ordering. Confirm that the 1206 package footprint matches your PCB layout constraints. Ensure compatibility with your chosen soldering process, as these components are designed for surface mount technology. Check for RoHS compliance status if required by your manufacturing standards.

Chip Ferrite Bead Selection Notes

Select this component when high impedance at 100 MHz is required for noise suppression in compact designs. The 350 mA current rating suits low-power signal lines rather than power distribution. Consider the 400 mΩ DC resistance impact on signal integrity. The multilayer structure allows for smaller footprints compared to conventional beads, making it suitable for space-constrained applications.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FB series of multilayer ceramic components from Cal-Chip Electronics. These chips integrate magnetic material within a layered structure to provide effective EMI suppression. The series is engineered for reliability in surface mount environments, offering consistent performance across various electronic assemblies where noise reduction is critical.

Chip Ferrite Bead Replacement Considerations

The FB321611T-152Y-S-1 is a related variant with identical impedance but lower DC resistance. Verify if the reduced resistance meets your specific circuit requirements. No other direct substitutes are confirmed in public documentation.
