DRQ73-8R2-R – COILTRONICS

Overview

The Eaton DRQ73-8R2-R is a shielded, dual-coil inductor array designed for robust performance in demanding electronic systems. Its primary function is to provide controlled impedance and energy storage, with a critical operational characteristic being its configurable inductance (8.93 µH parallel, 35.72 µH series). A key design consideration is the trade-off between the higher series inductance and its associated lower current handling (1.1A) versus the lower parallel inductance with its increased current capacity (2.19A), requiring careful selection based on the specific circuit’s power and noise requirements.
