SRF0602-470Y

Overview

The Bourns SRF0602-470Y is a surface-mount common mode filter choke from the SRF0602 series, designed for high-frequency noise suppression. It features an inductance of 47 µH with a tolerance of ±50% and a maximum DC resistance of 160 mΩ. The component supports a maximum DC current of 300 mA and provides an impedance of 140 Ω at 4 MHz. Operating within a temperature range of -40°C to +105°C, it utilizes ferrite core material and is housed in a compact 0602 package measuring 6.5 mm x 3.6 mm x 1.65 mm.

Feature Summary

• Provides effective common mode noise filtering across a wide frequency spectrum from 4 MHz to 1600 MHz.
• Utilizes a compact 0602 surface-mount footprint to facilitate space-constrained PCB layouts.
• Constructed with ferrite core material to ensure stable performance under specified operating conditions.

Applications
