Overview
The 1008HC-392EJFS is an unshielded drum core, wirewound fixed inductor from the Delta Electronics 1008HC series. It features a nominal inductance of 3.9 µH with a tolerance of ±5%. The component has a maximum DC resistance (DCR) of 800 mΩ and a rated current of 450 mA. It utilizes a ceramic core material and is housed in a 1008 (2520 Metric) surface-mount package measuring 2.92mm x 2.79mm x 2.03mm max. The device operates within a temperature range of -40°C to +125°C.
Feature Summary
- Unshielded drum core wirewound construction for high-frequency stability
- Ceramic core material supporting operation up to 125°C
- Surface-mount design compatible with automated assembly processes
Applications
- RF filtering circuits
- Power supply output chokes
- Signal conditioning modules
Procurement Notes
Verify the specific suffix EJFS against official Delta Electronics documentation to confirm tolerance and packaging details. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.
Selection Notes
Select this component when a 3.9 µH inductance value is required in a compact 1008 footprint. Consider the 450 mA current rating and 800 mΩ DCR for power loss calculations. Verify that the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field emission.
Part Context
This part belongs to the Delta Electronics 1008HC series of fixed inductors. These components are designed for portable devices, cloud computing equipment, automotive systems, and IoT applications. The series offers various inductance values in a standardized 1008 metric package size.
Replacement Considerations
Check for direct substitutes within the same 1008HC series or other manufacturers offering identical 3.9 µH, 450 mA specifications in a 1008 package. Ensure pinout and physical dimensions match to avoid PCB rework.
