SRF0703-3R3M

The SRF0703-3R3M is a dual coil surface mount inductor array designed for space-constrained electronic applications. Manufactured by Bourns, this component integrates two independent 3.3 µH inductors into a single compact footprint. Each coil exhibits a maximum DC resistance of 31.6 mOhm, ensuring minimal power loss and efficient current handling in signal processing paths.

This inductor array utilizes a shielded construction typical of the SRF series, which reduces electromagnetic interference and minimizes magnetic coupling between adjacent coils. The surface mount design facilitates automated PCB assembly and supports high-volume manufacturing workflows. Engineers can utilize this component in filtering stages, power supply input/output circuits, and RF signal conditioning networks where stable inductance and low parasitic resistance are required.

The ±20% tolerance on the 3.3 µH rating provides standard flexibility for general-purpose analog and digital circuit designs. Its standardized package dimensions allow for straightforward layout integration alongside other passive components. Procurement teams should verify mechanical mounting requirements against specific PCB land patterns before finalizing bill of materials.
