103R-152J

Overview

The Delevan 103R-152J is an unshielded surface-mount RF inductor with a nominal inductance of 1.5 µH and a tolerance of ±5%. It features a maximum DC resistance of 0.84 ohms and a rated current of 340 mA. The component has a minimum Q factor of 22 and a self-resonant frequency of 115 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

• Unshielded wirewound construction for RF applications
• Standard two-terminal surface mount design
• Ferrite core material for stable inductance

Applications

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

Procurement Notes

Verify the manufacturer designation, as sources list both Delevan and API Delevan Inc. Confirm RoHS compliance status through official documentation. Ensure the ordering suffix matches the required tolerance and packaging format. Cross-reference the Mouser number 807-103R-152J for accurate identification during sourcing.

Selection Notes

Select this component for applications requiring a 1.5 µH inductance with a 340 mA current rating. The unshielded design allows for flexible layout but requires consideration of magnetic coupling. The 115 MHz self-resonant frequency limits high-frequency usage above this threshold. Compare DCR and Q factors against circuit requirements for optimal performance.

Part Context

This part belongs to the 103/R series of fixed RF inductors from Delevan. The series offers various inductance values in a consistent 100 mil footprint. These components are designed for general-purpose RF applications where unshielded inductors are suitable for the circuit topology.

Replacement Considerations

Direct substitutes include other 1.5 µH SMD RF inductors with similar current ratings and dimensions. Verify that replacement parts maintain the same unshielded configuration and Q factor specifications to ensure circuit compatibility.
