CT0805CSF-820J

Fixed Inductors Overview

The CT0805CSF-820J is a general purpose wire-wound chip inductor manufactured by Central Technologies. It features a ceramic core and is housed in an SMD 0805 rectangular package. The component has a nominal inductance of 0.082 µH with a ±5% tolerance code J. It exhibits a maximum DC resistance of 0.37 Ω and a minimum quality factor of 48 at the nominal inductance. The device supports a maximum rated current of 0.4 A and operates within a temperature range of -40 °C to 125 °C.

Fixed Inductors Feature Summary

• Utilizes a ceramic core for stable inductance characteristics
• Designed as a high-current inductor for power applications
• Compliant with RoHS standards and lead-free construction

Fixed Inductors Applications

• Filter choke circuits
• RF inductor applications
• High current inductor implementations

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' corresponds to the required ±5% tolerance when ordering, as other codes like G, K, or M denote different tolerances. Confirm the 0805 package dimensions match the target PCB footprint. Ensure the 0.4 A current rating and 0.37 Ω DC resistance meet the circuit requirements. Check that the operating temperature range of -40 °C to 125 °C is suitable for the environment.

Fixed Inductors Selection Notes

Select this component for applications requiring a compact 0805 form factor with moderate inductance. The ceramic core construction offers reliability for general purpose use. Consider the 0.4 A current limit and 0.37 Ω resistance for power loss calculations. The part is suitable for filtering and RF tasks where space is constrained but higher current handling than smaller packages allows.

Fixed Inductors Part Context

This part belongs to the CT0805CSF series of wire-wound chip inductors from Central Technologies. The series covers a wide range of inductance values from low nanohenries to microhenries within the 0805 package. Variants differ primarily in inductance value and tolerance codes (G, J, K, M). This specific model represents a mid-range inductance option within the family.

Fixed Inductors Replacement Considerations

Direct substitutes may include other manufacturers' 0805 wire-wound inductors with 0.082 µH nominal value and ±5% tolerance. Verify that replacement parts match the 0.37 Ω max DC resistance and 0.4 A current rating. Ensure the replacement also uses a ceramic core and fits the 0805 SMT package dimensions.
