Overview
The PE-0201FB220ST is a surface-mount ferrite bead from Pulse Electronics, designed for signal line filtering. It features a single-line configuration in a compact 0201 (0603 Metric) package with dimensions of 0.024 inches in length. The component provides an impedance of 22 Ohms at 100 MHz and supports a maximum DC current of 1 Ampere. Its DC resistance is specified at 65 milliohms, ensuring minimal insertion loss while effectively attenuating high-frequency noise.
Feature Summary
- Provides effective high-frequency noise suppression for sensitive signal lines
- Compact surface-mount footprint suitable for space-constrained designs
- Low DC resistance to maintain signal integrity under load
Applications
- High-speed digital signal line filtering
- RF circuit noise attenuation
- Portable electronic device signal conditioning
Procurement Notes
Verify the exact part number against official Pulse Electronics documentation to confirm specifications. Note that availability may vary as components can be subject to discontinuation or lifecycle changes. Ensure compatibility with your PCB layout and thermal requirements before finalizing procurement decisions.
Selection Notes
Select this component when a low-profile, single-line ferrite bead is required for signal integrity management. The 0201 package size is ideal for dense PCB layouts. Consider the 22 Ohm impedance at 100 MHz to ensure it matches the target noise frequency spectrum. Verify that the 1A current rating exceeds the maximum operating current of the protected line.
Part Context
This ferrite bead belongs to Pulse Electronics' series of chip ferrite beads, which are widely used in consumer electronics and telecommunications. The 0201 form factor represents one of the smallest standard packages, allowing for miniaturization of modern electronic devices without compromising filtering performance.
Replacement Considerations
Consult official manufacturer substitution lists for verified alternatives. Generic equivalents may differ in impedance characteristics or current handling capabilities. Ensure any replacement maintains the same package dimensions and electrical parameters to fit existing footprints.
