Key Features

The DR331-2-332 is part of Bourns’ compact, low-profile surface mount inductor series designed for efficient energy storage and filtering. This 3.3 µH model supports a maximum rated and saturation current of 2.0 A, offering dependable performance in power-sensitive circuits. Its DCR of 0.08 ohms minimizes energy loss, enhancing system efficiency. The inductor is constructed with a molded body, providing structural integrity and shielding in EMI-sensitive applications.

Additionally, the DR331-2 series operates across a wide temperature range of -40°C to +85°C, making it ideal for industrial and consumer-grade electronics. The component’s compact dimensions and standardized pad layout ensure easy PCB integration. As a lead-free, RoHS-compliant component, it also supports global environmental standards.

Applications

DC-DC converters
Switch-mode power supplies
Noise suppression circuits
Consumer electronics
Industrial automation

Product Overview

The DR331-2-332 is engineered for use in circuits where compact size, thermal performance, and magnetic stability are critical. Its high-current handling and low resistance allow it to perform reliably under load, while the self-resonant frequency of 70 MHz ensures stability in high-frequency environments. Because it is part of a broad inductance range series (from 1 µH to 1000 µH), this model can be easily paired with others for flexible design options. Its compatibility with automated SMT processes also aids efficient production and long-term reliability.
