SRN4018-470M Description

Short technical summary and product information.

The Bourns SRN4018-470M is a semi-shielded power inductor from the SRN4018 series. It offers a nominal inductance of 47 µH with a tolerance of ±20% and a maximum DC resistance of 780 mΩ. This wirewound, drum core inductor is designed for surface mounting and operates within a temperature range of -40°C to +125°C.

 

With a rated current of 600mA and a Q factor of 11 at 2.52MHz, this component is suitable for various applications including DC/DC converters, notebook computers, and digital video cameras. The low profile design, with a maximum height of 1.80mm, makes it ideal for space-constrained electronic devices. It is also RoHS compliant and halogen-free.

 

The inductor has a typical self-resonant frequency of 10 MHz. The construction utilizes a ferrite core and enameled copper wire, with Sn/Ag/Cu terminal finish and magnetic epoxy resin coating. It is supplied in a standard package of 3000 pieces per 13-inch reel.
