Overview
The Delevan 0819-36H is a fixed axial leaded RF inductor from the 0819 series. It features a molded unshielded coil construction with an inductance of 3.3 µH and a tolerance of 1%. The component has a maximum DC resistance of 1.2 Ohms and supports a maximum DC current of 198 mA. Key electrical characteristics include a minimum Q factor of 45 and a self-resonant frequency of 100 MHz. The physical dimensions are 5.08 mm in length and 1.98 mm in diameter, designed for PCB mount applications.
Feature Summary
- Molded unshielded coil construction for compact integration
- Axial leaded termination style for through-hole mounting
- High precision 1% inductance tolerance
Applications
- RF circuit filtering
- Impedance matching networks
- General purpose RF inductor applications
Procurement Notes
Verify RoHS compliance status as documentation indicates non-compliance. Confirm lead content and material composition requirements against project specifications. Ensure the manufacturer API Delevan is the authorized source for this specific part number to guarantee authenticity and traceability.
Selection Notes
Select this component when a high-precision 3.3 µH inductance is required in an axial package. The 1% tolerance suits tight circuit tolerances. Consider the 198 mA current rating and 1.2 Ohm DCR for power handling needs. The unshielded design requires layout consideration for magnetic interference.
Part Context
This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values with different tolerance codes (e.g., G for 2%, H for 3%). The 0819-36H specifically denotes the 3.3 µH value with 1% tolerance, distinguishing it from other variants in the same physical footprint family.
Replacement Considerations
Cross-reference with other 3.3 µH axial RF inductors if availability is constrained. Verify that substitute components match the 1.2 Ohm DCR and 198 mA current limits. Ensure the replacement maintains the 100 MHz self-resonant frequency characteristic.
