Selecting Planar Cores For Your Power Applications
1.
2. Planar cores are the best alternative to conventional
ferrite cores when there isa need for a low-profile
magnetic device. Their shape issuitable for PCB
mounting and they have low losses and high saturation
levels. These cores are commonly integrated withPrinted
Circuit Boards (PCBs) used in the power supplymarket.
In this blog, we’re going to discuss Planar cores &how
they are an appropriate choice for your power
applications. Let’sget started!
3. What is the purpose of using Planar Cores?
Planar cores are used to make inductive components
where windings are fabricated with the help of
printed circuit tracks or copper stampings. Then, they
are separated by insulating sheets or constructed
using multiple-layered circuit boards.
4. Their windings are influenced by advanced computeraided
manufacturing technologies.
They have superior thermal features because of a larger
surface-to-volume ratio as compared to other ferrite cores.
They have excellent modularity, so no additionalcomponents
are required.
They are available in a variety of shapes &sizes from 10mmto
25mm.
The operating temperature range isbetween -30°C to105°C.

Advantages of Planar Cores
6. Major Types of Planar Cores
1.Planar (EI,EE) Cores
These cores are ideal for manufacturing gapped inductors
where fringing losses have to be taken into consideration. These
cores are a little more expensive than other cores but have no
wasted space.
2. EIH, EEHCores
These cores are produced using optimum grade raw material &
advanced technology. They are also a little moreexpensive than
other conventional ferrite cores.
7. Applications
Planar cores are primarily used for commercial electronics. Below are some
of their common applications.
Power Components
-Power Transformers
-Mains FilterChokes
AC/DC Converter
-Stand AloneSMPS
-Battery Chargers (Mobile Phones &
Computers) DC/DC Converter
-Power Converter Modules
-Telecommunications Network
-Mobile Phones (Mains powersupply)
8. Designing of Planar Cores
The height of an individual component can be decreased by
sinking the ferrite core through a slot in the motherboard. Thisis
pressed until the windings are placed on themotherboard.
In another technique, hybrid mounting, apart of the windings are
placed on the motherboard while others are joined in a multi-
layered circuit board. The motherboard should have slots to
maintain space for the ferritecore.
9. Conclusion
Planar cores have become an important component to achieve
high efficiency and high power density converter amidst the
increasing frequencies. Ifyou are looking for planar cores foryour
