103R-561J

Overview

The Delevan 103R-561J is a fixed surface-mount inductor with an inductance of 560 nH and a tolerance of ±5%. It features a maximum DC resistance of 278 mΩ and a rated current of 590 mA. The component utilizes a ferrite core and operates within a temperature range of -55°C to +125°C. Its physical dimensions are 2.54 mm x 2.54 mm, and it exhibits a self-resonant frequency of 195 MHz.

Feature Summary

• Unshielded design suitable for compact RF applications
• Ferrite core construction for stable inductance
• Surface-mount package for automated assembly

Applications

• RF signal filtering
• Impedance matching networks
• High-frequency circuit decoupling

Procurement Notes

Verify the specific suffix 'J' corresponds to the required ±5% tolerance during procurement. Confirm that the nonstandard two-lead package aligns with the PCB footprint requirements. Ensure the selected distributor sources directly from API Delevan to guarantee component authenticity and traceability.

Selection Notes

Select this component when a low-inductance value near 560 nH is required for high-frequency operation. Consider the 590 mA current rating against the expected load current. Evaluate the 278 mΩ DCR impact on power loss. Compare the 195 MHz self-resonant frequency against the target operating frequency to ensure effective performance.

Part Context

This part belongs to the 103 series of fixed inductors from API Delevan. These components are designed for general-purpose and RF applications requiring small form factors. The series offers various inductance values with consistent packaging standards for easy integration into electronic circuits.

Replacement Considerations

The 103-561F is a comparable unshielded inductor with identical electrical parameters but a ±1% tolerance. Verify if the tighter tolerance meets the design requirements before substitution.
