105-821F

Overview

The Delevan 105-821F is a surface-mount RF inductor from the 105 series, featuring an iron core and epoxy encapsulation. It provides a nominal inductance of 2.7 µH with a tight tolerance of 1%. The component has a maximum DC resistance of 2 ohms and operates within a temperature range of -55°C to +125°C. Designed for PCB mounting, it utilizes a 1010 package footprint.

Feature Summary

• Epoxy encapsulated construction for environmental protection
• Iron core design optimized for RF applications
• High precision tolerance for stable circuit performance

Applications

• RF signal processing circuits
• General purpose inductor applications requiring high stability
• PCB mounted RF filtering networks

Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead times and availability directly with API Delevan or authorized distributors due to potential supply constraints. Ensure ordering specifications match the required tolerance and current ratings for your specific application design.

Selection Notes

Select this component when a 2.7 µH value with 1% tolerance is required in a compact SMD form factor. Consider the 2-ohm DC resistance limit for current handling capabilities. Verify that the 1010 package dimensions fit the target PCB layout and that the operating temperature range meets system requirements.

Part Context

Part of the Delevan 105 series of fixed RF inductors. This series typically features iron cores and epoxy encapsulation for durability. The 105-821F specifically targets applications needing precise inductance values in a small surface-mount package.

Replacement Considerations

Direct substitutes may include other 2.7 µH SMD inductors with similar tolerance and package size. Verify electrical parameters such as DCR and saturation current before substitution. Check for equivalent shielding characteristics if EMI is a concern.
