0805CT-332EKFS

Overview

The Delta Electronics/Components 0805CT-332EKFS is a fixed wirewound inductor with a nominal inductance of 3.3 µH and a tolerance of ±10%. It features an unshielded drum core design using ferrite material, housed in a standard 0805 (2012 Metric) surface-mount package measuring 2.29mm x 1.71mm x 1.45mm maximum height. The component has a DC resistance (DCR) of 1.4 Ohms and a rated current of 450 mA. It exhibits a self-resonant frequency of 70 MHz and a Q factor of 15 at 7.96 MHz. The device operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Unshielded drum core wirewound construction for moderate inductance applications
• High operating temperature capability up to 125°C
• Surface mount compatibility with standard 0805 footprint dimensions

Applications

• General-purpose signal filtering in electronic circuits
• Power supply input/output stages requiring moderate current handling
• RF choke applications below the self-resonant frequency limit

Procurement Notes

Verify the specific suffix EKFS against official Delta Electronics documentation to confirm exact electrical tolerances and packaging specifications. Ensure the procurement channel provides valid traceability for RoHS3 compliance. Cross-reference the manufacturer part number with authorized distributor databases to avoid counterfeit components. Confirm that the requested quantity aligns with standard reel or cut tape availability policies defined by the supplier.

Selection Notes

Select this component when a 3.3 µH inductance value is required with a 450 mA current rating in a compact 0805 package. Consider the 1.4 Ohm DCR for voltage drop calculations in low-voltage circuits. The unshielded design may require layout considerations for electromagnetic interference compared to shielded alternatives. Verify that the 70 MHz self-resonant frequency meets the operational bandwidth requirements of the target application.

Part Context

This component belongs to the Delta Electronics 0805CT series of fixed wirewound inductors. The series offers various inductance values within the 0805 surface-mount form factor. The CT designation typically indicates specific core material and performance characteristics distinct from other Delta series like the 0805CS. These components are designed for general electronics manufacturing where space efficiency and reliable inductance are prioritized.

Replacement Considerations

Direct substitutes include the 0805CT-332EKFST if available, though verification of identical DCR and current ratings is essential. Other manufacturers offering 3.3 µH 0805 unshielded inductors with similar 450 mA ratings may serve as functional equivalents, provided pinout and thermal characteristics match.
