Fixed Inductors Procurement Notes

Verify the part number suffix J indicates ±5% tolerance when ordering. Confirm the manufacturer is Central Technologies to ensure authenticity. Check date codes for recent production batches if long-term storage is required. Ensure the supplier provides genuine factory-sealed packaging. Cross-reference specifications against official datasheets before finalizing procurement.

Fixed Inductors Selection Notes

Select this component for applications requiring low inductance values near 0.33 µH. The 650 mA rated current supports moderate power handling requirements. The 550 MHz self-resonant frequency defines the upper operational limit for effective inductive behavior. Consider the 0.35 Ω DC resistance for voltage drop calculations in series configurations.

Fixed Inductors Part Context

This component belongs to the CT0805FSF series of fixed inductors from Central Technologies. The series offers various inductance values within the 0805 surface mount package size. Other variants include different inductance ratings such as 151 or 472, maintaining similar physical dimensions and construction methods across the product line.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 0.33 µH inductance, 0805 package, and comparable current ratings. Verify that alternative components maintain similar self-resonant frequencies to ensure RF performance consistency. Check for equivalent DC resistance values to prevent thermal issues in existing designs.
