1812-101G

Fixed Inductors Overview

The Delevan 1812-101G is a fixed surface-mount inductor with an inductance of 100 nH and a tolerance of ±2%. It features a maximum DC current rating of 818 mA and a maximum DC resistance of 300 mOhms. The component utilizes an unshielded design with a ferrite core, suitable for high-frequency applications. Its physical dimensions are standardized to the 1812 package size, measuring 4.5 mm in length, 3.2 mm in width, and 2.5 mm in height.

Fixed Inductors Feature Summary

• Unshielded construction designed for minimal parasitic effects in high-frequency circuits
• Ferrite core material provides stable inductance characteristics
• Surface-mount technology enables automated PCB assembly

Fixed Inductors Applications

• RF filtering networks
• High-frequency signal processing circuits
• Impedance matching stages

Fixed Inductors Procurement Notes

Verify RoHS compliance status as historical data indicates potential lead content. Confirm the specific manufacturing date code against project requirements. Ensure the unshielded variant matches the schematic design intent regarding electromagnetic interference. Validate that the 1812 footprint aligns with the board layout constraints.

Fixed Inductors Selection Notes

Select this component when low inductance values near 100 nH are required for RF applications. The unshielded design is preferred over shielded types to reduce core losses at high frequencies. Ensure the operating current remains below the 818 mA limit to prevent saturation. Verify thermal management capabilities given the small surface-mount package.

Fixed Inductors Part Context

This part belongs to the API Delevan 1812 series of unshielded surface-mount inductors. These components are engineered for general-purpose high-frequency applications where compact size and low inductance are critical. The series offers various inductance values within the same mechanical footprint to simplify supply chain management.

Fixed Inductors Replacement Considerations

Direct substitutes include the S1812-101G from the same manufacturer family, which shares identical electrical parameters but differs in shielding configuration. Cross-referencing with other manufacturers requires verifying exact inductance, tolerance, and current ratings.
