The PE-0402FB601ST is a surface-mount ferrite bead from Pulse Electronics, designed for signal line applications. It features a 0402 (1005 Metric) package and supports one signal line. The component provides an impedance of 600 Ohms at 100 MHz with a maximum DC resistance of 550 mOhms. It has a current rating of 300 mA and operates within a temperature range of -40°C to 105°C.
Verify the specific datasheet version for the PE-0402FB601ST to confirm exact impedance curves and thermal characteristics. Ensure compatibility with standard 0402 footprints during PCB layout. Confirm that the 300 mA current rating meets the operational requirements of the target circuit under all expected load conditions.
Select this component when space constraints require a 0402 footprint for EMI suppression. The 600 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. Verify that the 300 mA current handling capability aligns with the signal line's maximum operating current to prevent saturation or excessive heating.
This ferrite bead belongs to Pulse Electronics' series of passive components for electromagnetic interference suppression. It complements other signal line filters in the same package family, offering standardized mounting dimensions while providing targeted frequency-dependent attenuation for digital and analog signal integrity.
Compatible substitutes include PE-0402FB102ST and PE-0402FB121ST from the same manufacturer. These alternatives offer different impedance values (1 kOhm and 120 Ohm respectively) while maintaining the same 0402 package and single-line configuration for direct footprint replacement.
