Product Description

Bourns SRN4026 is a shielded wirewound surface mount inductor equipped with a ferrite core, providing an inductance of 1 μH with ±30% tolerance and rated maximum DC current of 3 A, making it suitable for high-performance electronic applications.

This inductor is built with a 4026 case size, featuring a length and depth of 4 mm and a height of 2.5 mm, optimized for space-constrained surface mount technology (SMT) designs.

The ferrite core enhances magnetic properties while the semi-shielded wirewound construction reduces electromagnetic interference, contributing to improved signal integrity and overall device performance.

It supports a broad operating temperature range from -40°C up to 125°C and has a maximum DC resistance of 16 mΩ. The termination style is solder, ensuring robust electrical and mechanical connections.

Certified to RoHS standards, the SRN4026 series is molded for durability and reliability in various industrial and commercial applications.

Common applications include DC/DC converters, notebooks, digital video cameras, hard disk drives, cellphones, televisions, and LCD displays, where efficient power management and EMI reduction are critical.

The 4026 package is a miniature surface mount configuration allowing compact PCB real estate utilization. Its 3 A current rating suits power supply circuits requiring moderate current handling capabilities. The high quality factor (Q:9) ensures low energy losses at the operating frequency up to 100 MHz.

Semi-magnetic shielding benefits applications sensitive to electromagnetic interference. The product is ideal for industrial, laboratory, consumer electronics, and communication equipment manufacturing sectors.
