1008HS-473EKFS

Overview

The 1008HS-473EKFS is a fixed surface-mount inductor from Delta Electronics/Components, housed in a 1008 (2520 Metric) package. It features an unshielded drum core wirewound construction with a ceramic magnetic core. The component provides an inductance of 47 µH with a tolerance of ±10%. It has a DC resistance (DCR) of 5.9 Ohms and a rated current of 120 mA. The self-resonant frequency is specified at 14 MHz. Operating temperature range extends from -40°C to 125°C.

Feature Summary

• Unshielded drum core wirewound design for high-frequency applications
• Ceramic magnetic core construction
• Surface mount installation in 1008 package

Applications

• RF circuit filtering
• Power supply output chokes

Procurement Notes

Verify part availability status as the 1008HS-473EKFS is listed as obsolete and no longer manufactured by the original producer. Confirm RoHS3 compliance requirements during sourcing. Check for authorized distributors holding remaining stock or consider approved substitute components if new production units are required for manufacturing.

Selection Notes

Select this component for designs requiring 47 µH inductance in a compact 1008 footprint. Ensure the circuit current does not exceed the 120 mA rating to prevent saturation. Verify that the 5.9 Ohm DCR aligns with power loss constraints. Consider the 14 MHz self-resonant frequency limit for high-speed signal integrity.
