Overview

The Coilcraft DO3316P-153MLB is a wirewound power inductor designed for efficient energy storage in DC-DC converter circuits. Its core characteristic is the 15 µH inductance, crucial for filtering ripple current and maintaining stable output voltages. A significant design consideration for this unshielded ferrite core inductor is the trade-off between its relatively high saturation current of 3 A and its self-resonant frequency (SRF) of 27 MHz; designers must ensure the operating frequency remains well below the SRF to avoid parasitic resonance and maintain effective inductance.

Key Features

Inductance: 15 µH ±20%
Saturation Current (Isat): 3 A
Maximum DC Current (Idc): 3.1 A
Maximum DC Resistance (DCR): 46 mOhms
Operating Temperature Range: -40°C to +85°C
Package Dimensions: 12.95 mm x 9.4 mm x 5.21 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.

Switching regulator output filtering in portable power supplies
Input ripple current reduction in battery-powered devices
Energy storage for buck and boost converter stages
EMI suppression in low-frequency power conditioning circuits
