Overview

The Coilcraft DO3308P-154MLB is a high-performance, surface-mount power inductor designed for efficient energy storage and filtering in DC-DC converter circuits. Its ferrite drum core construction facilitates a substantial inductance of 150 µH, crucial for smoothing ripple currents. A key design consideration for this unshielded component is managing radiated EMI, as its open magnetic path necessitates careful PCB layout and potential shielding in sensitive applications to avoid coupling into adjacent circuitry, a trade-off for its cost-effectiveness and compact form factor.

Key Features

Inductance: 150 µH
Tolerance: ±20%
Maximum DC Current (I_DC): 620 mA
Saturation Current (I_SAT): 740 mA
Maximum DC Resistance (DCR): 940 mOhms
Dimensions: 9.4 mm x 3 mm x 12.95 mm

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Buck converter output filtering for voltage regulation
Input ripple current reduction in battery-powered devices
Energy storage in boost converter topologies
EMI suppression in power supply input stages
