Overview
The PM2002-300-RC is a surface-mount ferrite bead manufactured by Bourns Inc. in the 1812 (4532 Metric) package. It exhibits an impedance of 47 Ohms at 100 MHz and supports a maximum DC current of 5 A. The component features a low maximum DC resistance of 600 uOhms and operates within a temperature range of -55°C to 125°C.
Feature Summary
- Provides electromagnetic interference suppression through high-frequency impedance characteristics
- Designed for surface-mount integration in compact electronic assemblies
- Capable of handling high direct current loads with minimal resistive loss
Applications
- Power supply filtering circuits
- Battery charger input stages
- Portable device signal integrity management
Procurement Notes
Verify the specific datasheet version for the PM2002-300-RC to confirm impedance tolerance and thermal derating curves. Ensure the 1812 footprint matches the target PCB layout. Confirm RoHS compliance status if required by the final assembly specifications. Cross-reference the manufacturer's part number to avoid confusion with similar series components.
Selection Notes
Select this component when a 47 Ohm impedance at 100 MHz is required for noise attenuation. The 5 A current rating suits high-power applications where low DCR is critical. The 1812 package offers a balance between current capacity and board space. Verify that the operating temperature range meets the environmental requirements of the end-use application.
Part Context
This ferrite bead belongs to Bourns' passive component portfolio, designed for EMI suppression in modern electronics. Ferrite beads dissipate high-frequency noise as heat, protecting sensitive circuitry from electromagnetic interference. The PM2002 series is engineered for reliability in demanding power and signal lines across various industrial and consumer sectors.
Replacement Considerations
Consult official substitution guides for equivalent ferrite beads with matching 47 Ohm impedance and 1812 footprint. Verify current ratings and DCR limits before swapping. No specific substitute part numbers are publicly confirmed for this model.
