AFBC-SF0402-352T

Overview

The AFBC-SF0402-352T is a surface-mount ferrite bead from the Abracon AFBC-SF0402 series, housed in a 0402 (1005 metric) package. It provides an impedance of 3.5 kOhms at 900 MHz with a tolerance of ±25%. The component supports a maximum DC current of 270 mA and has a maximum DC resistance of 1.35 Ohms. It operates within a temperature range of -40°C to +85°C, with physical dimensions of 1 mm length, 0.5 mm height, and 0.5 mm width.

Feature Summary

• Provides high impedance for effective noise suppression in signal lines
• Compact 0402 surface-mount footprint for space-constrained designs
• Capable of handling specified DC bias currents without saturation

Applications

• Noise filtering in high-speed digital signal lines
• EMI suppression in portable electronic devices
• Power line filtering for sensitive ICs

Procurement Notes

Verify the specific impedance frequency rating and DC current limits against your circuit requirements before ordering. Confirm that the 0402 package size fits your PCB layout constraints. Ensure the operating temperature range meets your environmental specifications. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when high attenuation is needed at frequencies around 900 MHz. The low DC resistance minimizes voltage drop across the filter. The small form factor allows placement near noise sources or connectors. Consider the current rating to prevent performance degradation under load conditions.

Part Context

This ferrite bead belongs to Abracon's AFBC-SF0402 series, designed for compact electronics. The series offers various impedance values in a standard 0402 case. These components are commonly used in consumer electronics and communication devices where space is limited and EMI control is critical.

Replacement Considerations

Check datasheets for equivalent parts with matching 3.5 kOhm impedance at 900 MHz and similar current ratings. Verify package compatibility and thermal characteristics. Ensure substitute components meet the same RoHS and reliability standards.
