103R-332H

Overview

The Delevan 103R-332H is a surface-mount RF inductor designed for radio frequency applications. It features a nominal inductance of 3.3 µH with a tight tolerance of ±3%. The component exhibits a maximum DC resistance of 1.4 Ohms and utilizes an unshielded construction within a 1010 (2525 metric) package footprint. It supports PCB mounting via standard SMD/SMT terminations and operates reliably across a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded chip design optimized for RF signal integrity
• High precision inductance tolerance for stable circuit performance
• Robust thermal stability suitable for demanding environments

Applications

• RF filtering circuits
• Impedance matching networks
• Radio frequency signal processing

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are often managed by other entities. Confirm RoHS compliance status through official documentation prior to integration. Ensure the ordering suffix matches the required tolerance grade. Validate that the 1010 package dimensions align with the target PCB layout constraints.

Selection Notes

Select this component when precise inductance control is critical for RF stages. The unshielded nature requires careful layout planning to prevent magnetic coupling with adjacent traces. Consider the 1.4 Ohm DC resistance impact on series impedance. Verify availability of the specific tolerance variant required for the design specifications.

Part Context

This part belongs to the fixed inductor category, specifically tailored for high-frequency operations. It serves as a passive component essential for tuning and filtering in wireless communication devices. The 103R series typically offers compact form factors suitable for space-constrained modern electronics designs.
