Eaton Wirewound Shielded Surface Mount Inductor 33 μH ±20 % 3.84 A Maximum DC Current Ferrite Core DR125-330-R

The Eaton DR125-330-R is a wirewound, magnetically shielded surface mount inductor designed for efficient power management in electronics. Featuring a ferrite core and 33 μH inductance with a tolerance of ±20 %, this inductor supports a maximum DC current of 3.84 A and operates reliably over a temperature range of -40°C to 125°C. Its robust build, including a molded construction and a shielded core, minimizes electromagnetic interference, making it well-suited for applications in computers, DVD players, portable devices, LCD panels, and DC-DC converters.

This surface mount device comes packaged on a reel, enabling streamlined automated assembly in manufacturing. With a maximum DC resistance of just 50.5 mΩ and a maximum self-resonant frequency of 100 kHz, it delivers low loss and predictable filtering performance in buck, boost, forward, and resonant converter circuits. The 2-pin surface mount termination and compact dimensions (12.5 mm length, 6 mm height, 12.5 mm depth) allow integration into space-constrained PCB layouts commonly found in industrial, commercial, and consumer electronic products.

The DR series inductors from Eaton, formerly Bussmann Ideate, embody high power density magnetically shielded wirewound chokes with a maximum operating temperature of up to 125°C. The ferrite core material enhances inductance stability and efficiency while withstanding thermal stress. This makes the DR125-330-R ideal for noise filtering, EMI suppression, and energy storage in a wide range of industrial and laboratory electronics.
