1812R-330J

Fixed Inductors Overview

The Delevan 1812R-330J is a fixed surface-mount inductor with an inductance of 33 nH and a tolerance of 5%. It features an unshielded construction using a ferrite core, designed for RF applications. The component has a maximum DC current rating of 1 A and a maximum DC resistance of 150 mOhms. Its physical dimensions are 4.83 mm in length, 3.4 mm in width, and 3.4 mm in height, conforming to the 1812 package style.

Fixed Inductors Feature Summary

• Unshielded SMD design suitable for compact circuits requiring stable inductance
• Ferrite core construction optimized for RF signal handling
• Standard two-terminal SMT termination for PCB mounting

Fixed Inductors Applications

• RF circuit filtering
• Compact electronic signal processing
• General purpose RF inductance stabilization

Fixed Inductors Procurement Notes

Verify the manufacturer designation, as API Delevan components may be listed under either API or Delevan branding. Confirm RoHS compliance status through official documentation before integration. Ensure the unshielded variant matches the electromagnetic interference requirements of the target application environment.

Fixed Inductors Selection Notes

Select this component when a low-inductance value of 33 nH is required in a standard 1812 footprint. The unshielded design distinguishes it from shielded alternatives like the S1812R series. Verify that the 1 A current rating meets the operational load requirements and that the lack of shielding does not interfere with nearby sensitive components.

Fixed Inductors Part Context

This part belongs to the Delevan fixed inductor family, specifically utilizing the 1812 metric package size (4532). It serves as a passive component for managing high-frequency signals in space-constrained designs. The product line includes various inductance values within the same physical envelope to support diverse circuit topologies.

Fixed Inductors Replacement Considerations

Direct substitutes include other 33 nH unshielded 1812 SMD inductors with comparable current ratings. Shielded equivalents such as the S1812R series offer similar footprints but differ in magnetic containment. Cross-reference datasheets for exact DC resistance and saturation characteristics.
