2890-44J

Fixed Inductors Overview

The Delevan 2890-44J is a fixed axial leaded RF inductor from the 2890 series. It features an unshielded molded construction with a nominal inductance of 120 µH and a tolerance of ±10%. The component has a maximum DC resistance of 4.1 Ohms and a rated current of 219 mA. Key electrical parameters include a minimum Q factor of 95 at 790 kHz and a self-resonant frequency of 10 MHz. Physical dimensions are 7.11 mm in diameter by 22.86 mm in length, designed for through-hole PCB mounting.

Fixed Inductors Feature Summary

• Unshielded molded coil design suitable for general RF applications
• Axial leaded termination for standard through-hole mounting
• Iron core material providing stable inductance characteristics

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• General purpose radio frequency signal processing

Fixed Inductors Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance. Confirm package type (Tape & Reel vs. Cut Tape) and minimum order quantities directly with suppliers. Ensure the specific suffix matches required tolerance and packaging specifications before ordering.

Fixed Inductors Selection Notes

Select this component for applications requiring 120 µH inductance with moderate current handling up to 219 mA. The unshielded design requires consideration for electromagnetic interference in dense layouts. Verify that the 10% tolerance meets circuit precision requirements.

Fixed Inductors Part Context

This part belongs to the Delevan 2890 series of molded RF inductors. These components are characterized by their axial leaded form factor and unshielded construction, distinguishing them from shielded SMD alternatives within the manufacturer's portfolio.

Fixed Inductors Replacement Considerations

The 2890R-44G is a verified substitute offering identical 120 µH inductance and physical dimensions but with tighter ±2% tolerance. The 2890-32K is not a direct replacement due to differing inductance values.
