The soft magnetic materials available from CSC include the molybdenum permalloy powder cores(MPP cores), 

High flux powder cores and Sendust powder cores. These are used in transformers,chokes,inductors,noise 

filters,power factor correction,switch mode power supply,etc.These cores are supplied in a wide variety of 

shapes,sizes and magnetic characteristics. CSC's cores are made from inhance atomized metal powders.
What is Magnetic Powder Core?      
Powder cores are distributed air gap cores made
from ferrous alloy powders for low losses at
elevated frequencies.Small air gaps distributed
evenly throughout the cores increase the amount of
DC that can be passed through the winding before
core saturation occurs.
Powder cores are excellent as low loss inductors
for SMPS,switching regulators,noise filters,etc.

  Special Features of CSC's Magnetic Powder Cores  
CSC's Core Identification
Core Designation
Most CSC magnetic powder cores are marked according to the following
designation method. Cores smaller than 10mm OD are supplied without marking
due to the difficulty of printing on the small surfaces of cores. Cores are graded
into 2% bands of inductance, and the percentage deviation from nominal
inductance value is stamped on cores.
Tolerance & Grading
The inductance tolerances of CSC magnetic powder cores are +/-8%from nominal values.
Cores are graded into 2% inductance bands. The percentage inductance deviation and its
winding adjustment references for each band are shown below. Cores with special
tolerances are also available upon request.
