PE-0603FB221ST

Overview

The PE-0603FB221ST is a signal line ferrite bead manufactured by Pulse Electronics Corporation. It features a 0603 (1608 Metric) surface mount package with dimensions of 1.6 mm length, 0.8 mm height, and 0.8 mm width. The component provides an impedance of 220 Ohms at 100 MHz and supports a maximum DC current of 500 mA. Its direct current resistance is 250 mOhm. The device operates within a temperature range of -40°C to 105°C.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies
• Utilizes a compact surface mount design suitable for space-constrained printed circuit board layouts
• Constructed as a single-line filter component for signal integrity management

Applications

• High-speed data line filtering in portable electronic devices
• Noise suppression on clock signals in computing hardware
• EMI reduction in communication interface circuits

Procurement Notes

Verify the exact impedance tolerance and DC resistance values against the manufacturer's latest datasheet before integration. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Ensure compatibility with standard reflow soldering profiles for 0603 packages to maintain electrical performance and mechanical reliability during manufacturing.

Selection Notes

Select this component when a low-profile ferrite bead is required for single-line signal paths. The 0603 footprint allows for dense PCB routing. Consider the 500 mA current rating to ensure the component does not saturate under normal operating conditions. Verify that the 220 Ohm impedance at 100 MHz aligns with the noise frequency spectrum of the target application.

Part Context

This ferrite bead belongs to Pulse Electronics' passive component portfolio, designed for EMI suppression in modern electronics. It complements other signal conditioning components by providing targeted noise attenuation without introducing significant signal loss or distortion. The part is intended for use in consumer, industrial, and automotive applications requiring reliable high-frequency noise control.

Replacement Considerations

Consult official substitution guides for equivalent ferrite beads with matching impedance and current ratings. Verify package dimensions and terminal configurations to ensure mechanical fit. Cross-reference thermal characteristics and material composition to maintain compliance with regulatory standards.
