0819-50G

Overview

The Delevan 0819-50G is a fixed, unshielded molded axial leaded RF inductor designed for printed circuit board mounting. It features an inductance of 12 µH with a tight tolerance of ±2%. The component has a maximum DC resistance of 3 Ohms and supports a maximum DC current of 126 mA. Key electrical characteristics include a minimum Q factor of 40 and a self-resonant frequency of 23 MHz. Physical dimensions are 5.08 mm in length and 1.98 mm in diameter.

Feature Summary

• Unshielded molded construction for standard RF applications
• Axial leaded termination style for through-hole PCB integration
• High Q factor performance at operating frequencies

Applications

• RF signal processing circuits
• Impedance matching networks
• Filter design in radio frequency systems

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as availability may vary between tape-and-reel and bulk formats. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as historical data indicates non-compliance for this series. Cross-reference the manufacturer part number with the Mouser or DigiKey equivalent identifiers to ensure accurate procurement of the genuine API Delevan component.

Selection Notes

Select this component when a 12 µH inductance value is required with high precision. The 126 mA current rating dictates suitability for low-power RF stages rather than power handling applications. Ensure the PCB layout accommodates the 5.08 mm axial length and 1.98 mm diameter. Consider the unshielded nature of the coil regarding proximity effects in dense circuit layouts.

Part Context

This component belongs to the Delevan 0819 series of fixed inductors. The series offers various inductance values and tolerance grades, identified by alphanumeric suffixes. The 0819-50G specifically denotes the 12 µH variant within this molded, unshielded product line, sharing physical form factors with other members like the 0819-54G and 0819R-50G.

Replacement Considerations

Direct substitutes within the same series include the 0819R-50G, which shares identical electrical specifications but may differ in packaging or manufacturing lot details. Verify that any replacement maintains the 12 µH inductance, 2% tolerance, and 126 mA current rating to ensure circuit compatibility.
