Bourns SRN Semi-Shielded Power Inductor Series

Bourns has introduced the new SRN series of semi-shielded power inductors which are ideal for use in DC/DC converters.

  • Semi-shielded construction
  • Inductance range: 0.24 to 220 μH
  • High rated current - Irms up to 4.7 A Isat up to 8 A
  • RoHS compliant and halogen free

Product Description

Bourns has introduced the new SRN series of semi-shielded power inductors.
The SRN series combines the features of non-shielded and shielded inductors making them ideal for use in DC/DC converters which provide power management to mobile electronic devices computers data storage devices and consumer electronics.

Bourns' SRN series is also well-suited for industrial applications such as LED lighting control circuits and GPS equipment.
Bourns' new semi-shielded power inductor series includes models SRN2010 SRN2012 SRN2510 SRN2512 SRN4012 SRN4026 SRN5040 and SRN6028. These are designed using semi-magnetic shielding technology.

Instead of the conventional ferrite shield the magnetic shield of the SRN series uses an epoxy-ferrite powder mixture resin. This compound is applied to the perimeter of the inductor which envelops the winding. As a result the SRN model series inductors provide an effective magnetic shielding while emitting lower radiation compared to non-shielded inductors.
The power inductor family delivers high inductance with an inductance range of 0.24 to 220 μH. The series also features high-rated current with Irms up to 4.7 A and Isat up to 8 A. All the models are RoHS compliant and halogen free.

Typical applications

DC/DC converters Notebook computers Digital video cameras Hard drives Mobile phones TVs LCD displays.

Compliance

All models conform to RoHS and are halogen-free.

High rated current

Irms up to 4.7 A Isat up to 8 A.
