103R-151J

Overview

The Delevan 103R-151J is an unshielded surface-mount RF inductor with a nominal inductance of 150 nH and a tolerance of 5%. It features a maximum DC resistance of 175 mOhms and supports a maximum DC current of 745 mA. The component exhibits a minimum Q factor of 40 and a self-resonant frequency of 650 MHz. Its physical dimensions are 2.92 mm in length, 2.66 mm in width, and 2.41 mm in height.

Feature Summary

• Unshielded construction for minimal magnetic interference
• Designed specifically for radio frequency applications
• Standard dual-ended terminal placement for PCB mounting

Applications

• RF circuit design
• Radio frequency signal processing
• High-frequency filtering networks

Procurement Notes

Verify the manufacturer designation API Delevan or Delevan on official documentation to confirm authenticity. Ensure the part number suffix matches J for 5% tolerance. Cross-reference electrical parameters such as DCR and SRF against the specific datasheet provided by the supplier to guarantee compatibility with the target RF application requirements.

Selection Notes

Select this component when a low-inductance value near 150 nH is required for high-frequency operation up to 650 MHz. The 745 mA current rating suits moderate power RF stages. Consider the unshielded nature regarding nearby magnetic components. Compare against similar series parts if tighter tolerances or higher current capacity are needed for the specific circuit topology.

Part Context

This part belongs to the Delevan 103R series of fixed RF inductors. These components are characterized by their small surface-mount footprint and unshielded wire-wound construction. The series offers various inductance values optimized for RF environments, providing stable performance at high frequencies with standard two-terminal configurations.

Replacement Considerations

Direct substitutes include the 103R-151K for 10% tolerance variants. Other compatible options within the same family may include different tolerance suffixes if the circuit allows wider variance. Verify that any replacement maintains the 150 nH nominal value and comparable self-resonant frequency characteristics.
