105-181G

Overview

The Delevan 105-181G is an unshielded surface-mount RF inductor with a nominal inductance of 180 nH and a tolerance of ±2%. It features a maximum DC resistance of 190 mΩ and supports a maximum DC current of 710 mA. The component exhibits a minimum Q factor of 40 at 25 MHz and a self-resonant frequency of 405 MHz. Designed for PCB mounting, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded construction suitable for general RF applications
• High self-resonant frequency of 405 MHz
• Robust thermal stability across extended temperature ranges

Applications

• RF circuit filtering
• Impedance matching networks
• General-purpose RF signal processing

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status as documentation may vary by production batch. Ensure storage conditions maintain integrity prior to assembly. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when unshielded topology is required to minimize size or cost. Evaluate the 405 MHz self-resonant limit against target operating frequencies. Compare the 190 mΩ DCR against power loss requirements. Consider the 710 mA current rating relative to peak load currents in the specific circuit design.

Part Context

This part belongs to the Delevan fixed inductor family designed for surface-mount technology. It serves as a passive component for radio frequency signal handling. The manufacturer specializes in high-performance magnetic components for telecommunications and industrial electronics sectors.

Replacement Considerations

The 105-181JS offers identical electrical parameters with a ±5% tolerance instead of ±2%. The 105-181GS provides ±2% tolerance but may differ in specific manufacturing lot characteristics. Verify pin compatibility and thermal performance before substitution.
