Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in active production. Procurement should focus on identifying verified direct substitutes or authorized surplus stock. Verify part authenticity through official channels due to end-of-life status. Ensure replacement options meet identical electrical specifications and physical footprint requirements to maintain circuit integrity without redesign.

Selection Notes

Select this component for low-current, high-inductance applications where space is constrained within the 1008 footprint. The 4.7 µH value and 300 mA rating suit filtering tasks in portable and IoT devices. Consider the 43 MHz self-resonant limit when designing for higher frequencies. Evaluate thermal management needs given the 1.28 Ohm DCR and 125°C max operating temperature. Confirm RoHS3 compliance matches project regulatory requirements.

Part Context

Part of the 1008HS series, this inductor represents Delta Electronics' portfolio of passive magnetic components for consumer and industrial electronics.
