Overview
The SRU1038-470Y is a shielded SMD power inductor from Bourns, featuring a 47 uH inductance and a 1.6 A saturation current rating. Its drum core construction is enclosed in a magnetic shield to minimize electromagnetic interference (EMI) in sensitive circuits. The component is designed for reliable performance in power conversion applications within a temperature range of -40 C to +125 C.
Why Choose This Part
The shielded design provides excellent EMI suppression, making it suitable for high-density PCB layouts where noise crosstalk must be minimized. Its low profile of approximately 3.8mm allows for use in height-constrained applications without sacrificing the 1.6 A saturation current capability.
Applications
DC-DC Converters
Used as an energy storage element in buck, boost, and SEPIC topologies to provide smooth output current.
Input/Output Filters
Acts as a low-pass filter to reduce ripple and noise in power supplies for consumer and industrial electronics.
LED Drivers
Provides current regulation and filtering in switching power supplies for high-brightness LED arrays.
LCD Displays
Serves as a power inductor in the backlight drive circuitry for portable and desktop displays.
