103R-332K

Overview

The Delevan 103R-332K is a fixed surface-mount inductor with a nominal inductance of 3.3 µH and a tolerance of 10%. It features a maximum DC resistance of 1.4 Ohms and a rated current of 260 mA. The component utilizes a non-standard, two-lead SMD package without leads. Constructed with a ferrite core, it operates within a temperature range of -55 °C to +125 °C.

Feature Summary

• Non-shielded chip inductor design for general-purpose applications
• Ferrite core construction for stable magnetic properties
• Surface-mount termination configuration

Applications

• Power supply filtering circuits
• General purpose signal processing
• Electronic equipment choke applications

Procurement Notes

Verify the specific manufacturer source, as API Delevan has undergone corporate restructuring. Confirm RoHS compliance status and lead content, as historical data indicates variations between lead-free and lead-containing versions for this series. Ensure the non-standard package dimensions match the PCB footprint requirements before procurement.

Selection Notes

Select this component when a low-inductance value is required for high-frequency filtering or energy storage in compact designs. The 260 mA current rating suits low-power applications. Consider the unshielded nature for potential EMI constraints and verify that the non-standard package size fits the available board space compared to standard metric sizes.

Part Context

This part belongs to the Micro i? Chip Inductors series by API Delevan. It is distinct from the SP1812R and DC630R series which offer different current ratings and package styles. The 103R series is characterized by its small form factor and specific non-standard footprint designed for dense mounting.

Replacement Considerations

Cross-reference with other 3.3 µH SMD inductors having similar 260 mA ratings and 1.4 Ohm DCR. Verify package compatibility as the non-standard footprint may require adapter boards or layout changes for direct replacement.
