0819-96F

Overview

The Delevan 0819-96F is an axial leaded RF inductor with a nominal inductance of 1 mH and a tight tolerance of 1%. It features a molded unshielded coil construction, resulting in a maximum DC resistance of 79 Ohms and a rated maximum DC current of 24.5 mA. The component exhibits a minimum Q factor of 35 and a self-resonant frequency of 3.3 MHz. Physically, it measures 5.08 mm in length and 1.98 mm in diameter, designed for PCB mounting.

Feature Summary

• Molded unshielded coil construction for compact integration
• Axial lead termination style for through-hole PCB mounting
• High precision 1% inductance tolerance

Applications

• RF circuit filtering
• Impedance matching networks
• Tuned oscillator circuits

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct tolerance and packaging configuration. Confirm RoHS compliance status as indicated in the latest datasheet, noting that some listings may indicate non-compliance. Validate the supplier's authorization status directly with API Delevan or authorized distributors to guarantee component authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a precise 1 mH inductance is required for RF applications with strict tolerance limits. Ensure the operating current remains below the 24.5 mA maximum rating to prevent thermal issues due to the 79 Ohm DC resistance. Consider the unshielded design implications for nearby sensitive components and verify that the 3.3 MHz self-resonant frequency aligns with the target signal bandwidth requirements.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values with different tolerance codes, all sharing a standardized axial molded package. This specific model represents the higher inductance end of the standard range, utilizing a fine-wire winding technique to achieve the specified electrical characteristics within the compact physical footprint.

Replacement Considerations

Cross-reference with other 0819 series variants for different inductance values if specifications change. Verify mechanical compatibility with existing PCB footprints when substituting with similar axial inductors from other manufacturers.
