Overview
The PE-0603FB121ST is a single-line ferrite bead designed for signal line filtering applications. Manufactured by Pulse Electronics, this component utilizes a surface-mount package with dimensions of 0.063 inches in length and 0.031 inches in width (1.60mm x 0.80mm). It exhibits an impedance of 120 Ohms at a frequency of 100 MHz. The device supports a maximum rated current of 500mA and features a maximum DC resistance of 180 milliohms. It operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.
Feature Summary
- Provides effective high-frequency noise suppression for sensitive signal lines through controlled impedance characteristics.
- Utilizes a compact surface-mount footprint suitable for space-constrained printed circuit board layouts.
- Ensures reliable operation across extended industrial temperature ranges without performance degradation.
Applications
- High-speed digital signal processing circuits
- Data bus protection against electromagnetic interference
- Clock line filtering in microcontroller systems
Procurement Notes
Verify the specific manufacturer part number against official distributor catalogs to ensure authenticity. Confirm that the received components match the specified impedance and current ratings. Check for compliance documentation regarding RoHS3 regulations. Ensure storage conditions maintain component integrity prior to assembly.
Selection Notes
Select this component when signal line filtering requires a 120 Ohm impedance at 100 MHz. Consider the 500mA current rating to prevent saturation during normal operation. Evaluate the 0603 package size against available PCB real estate. Assess thermal requirements to ensure operation remains within the -40°C to 105°C range.
Part Context
This ferrite bead belongs to the PFB series from Pulse Electronics, specialized for EMI suppression in electronic circuits. It serves as a passive filter element to attenuate high-frequency noise while allowing desired signal frequencies to pass. The component integrates into standard surface-mount manufacturing processes for efficient assembly.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before considering alternative manufacturers or generic equivalents.
