Bourns Shielded Wirewound Surface Mount Inductor 4.7 μH 1.4 A Idc 40 MHz SRN4026

Bourns SRN4026 Shielded Wirewound Surface Mount Inductor is a miniature power inductor designed with a semi-magnetically shielded construction and a ferrite core. It provides an inductance value of 4.7 μH with a tolerance of ±20% and supports a maximum DC current of 1.4 A. The device is housed in a compact 4026 package with dimensions 4 mm length, 2.5 mm height, and 4 mm depth, ideal for space-sensitive applications.

This inductor is constructed with wirewound technology, ensuring enhanced electromagnetic interference (EMI) shielding and excellent performance in switching power supply circuits such as DC/DC converters. It operates reliably within a wide temperature range from -40°C to 125°C, making it suitable for industrial, automotive, and consumer electronics environments.

The maximum DC resistance value of 48 mΩ contributes to efficient power delivery with minimal loss. The termination style employs solder pads, facilitating easy surface mounting on printed circuit boards (PCBs) in automated production. The component meets RoHS environmental compliance for safer disposal and environmental impact reduction.

The maximum self-resonant frequency of 40 MHz with a minimum quality factor (Q) of 9 ensures effective filtering and noise suppression, critical in high-frequency circuits. Typical applications include use in notebook computers, digital video cameras, hard disk drives (HDDs), cell phones, televisions, and LCD displays.
