1008HS-392EJFS

Overview

The 1008HS-392EJFS is an unshielded drum core, wirewound fixed inductor from the Delta Electronics 1008HS series. It features a nominal inductance of 3.9 µH with a tolerance of ±10%. The component has a DC resistance (DCR) of 1.25 Ohms and a rated current of 310 mA. Designed for surface mount installation, it utilizes a ceramic magnetic core within a 1008 (2520 Metric) package measuring 2.92mm x 2.79mm x 2.10mm. It operates reliably within a temperature range of -40°C to +125°C.

Feature Summary

• Unshielded drum core wirewound construction for high-frequency stability
• Compact 1008 (2520 Metric) surface mount footprint
• Ceramic magnetic core material supporting wide operating temperatures

Applications

• RF signal processing circuits
• High-frequency power supply filtering
• General-purpose SMD inductive components

Procurement Notes

Verify the specific suffix EJFS against official Delta Electronics documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components and confirm current availability status.

Selection Notes

Select this component when an unshielded inductor is required to minimize parasitic capacitance in RF applications. The 1008 package size offers a balance between current handling capability and board space efficiency. Consider the 310 mA rating and 1.25 Ohm DCR for voltage drop and thermal management calculations in the target circuit design.

Part Context
