105R-331J

Overview

The Delevan 105R-331J is a fixed surface-mount inductor with a nominal inductance of 330 nH and a tolerance of ±5%. It features an unshielded construction with two leads. The component supports a maximum DC current of 620 mA and has a maximum DC resistance of 250 mOhms. It operates within a temperature range of -55°C to +105°C. The physical dimensions are 0.100 inches by 0.100 inches (2.54 mm x 2.54 mm).

Feature Summary

• Unshielded fixed inductor design for standard RF applications.
• Compact nonstandard footprint suitable for space-constrained PCB layouts.
• Operates reliably across a wide industrial temperature range.

Applications

• RF circuit filtering
• Signal processing networks
• General-purpose electronic equipment

Procurement Notes

Verify the specific suffix 'J' confirms the ±5% tolerance requirement. Ensure the unshielded characteristic aligns with EMI constraints. Confirm package dimensions match the target PCB footprint. Check RoHS compliance status if required by assembly standards.

Selection Notes

Select this part when a compact, unshielded inductor is required for low-current RF paths. Compare against shielded alternatives if magnetic interference is a concern. Verify that the 620 mA current rating meets the peak load requirements of the specific circuit application.

Part Context

This component belongs to the API Delevan fixed inductor family. It shares similar form factors with other series like the 103R and P3519. These components are designed for surface-mount technology integration in consumer and industrial electronics.
