Overview
The Delevan 108R-563GS is a fixed surface-mount inductor with an inductance of 56 µH and a tolerance of ±2%. It features an unshielded design utilizing a nonstandard two-lead configuration. The component has a maximum DC resistance of 23 Ohms and a rated current of 33 mA. Electrical performance includes a minimum Q factor of 30 at 2.5 MHz and a self-resonant frequency of 8.5 MHz. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Unshielded construction for specific electromagnetic interference requirements
- Nonstandard two-lead surface mount package format
- Ferrite core technology supporting high-frequency operation
Applications
- RF signal filtering circuits
- High-frequency impedance matching networks
- General-purpose RF chokes
Procurement Notes
Verify the specific lead configuration and physical dimensions against the official datasheet before integration, as the nonstandard package may differ from standard SMD footprints. Confirm that the 33 mA current rating aligns with the application's peak load requirements to prevent saturation or thermal issues during operation.
Selection Notes
Select this component when a 56 µH value is required in an unshielded form factor. The 23 Ohm DC resistance limits suitability for high-current power applications; it is optimized for low-current RF environments where the 8.5 MHz self-resonant frequency defines the operational bandwidth constraints.
Part Context
This part belongs to the Delevan fixed inductor portfolio, characterized by specialized surface-mount packages. The 108R series designation indicates a specific footprint and lead style distinct from standard rectangular chip inductors, catering to designs requiring precise spatial arrangement or specific mounting orientations.
Replacement Considerations
Direct substitutes must match the 56 µH inductance, 33 mA current rating, and 23 Ohm resistance. Verify that alternative components support the same nonstandard two-lead SMD footprint and maintain comparable Q factor and self-resonant frequency specifications.
