Because of distributed air gap properties, Iron powder core is well suitable to the application of energy storage inductors and have a excellent inductance stability under high DC bias condition.
Owing to its low cost, Iron powder core can be an alternative choice to MPP, High Flux or Sendust core. |

|
 Excellent Frequency Characteristics(Maximum 200MHz)
Excellent Inductance stability under high DC bias condition.
Good temperature stability.
Inductors for High "Q"
Relatively high Saturation Flux Density
Large energy storage capacity.
Low core loss
Cost effecitive design. |

General operating temperature of Core Electronics' iron powder core is from -55℃ to +125℃.
When iron power cores are exposed to elevated temperature, a permanent decrease of inductance
and Q factor wilI be gradually occurred.
Degree of these changes depends on time, temperature, core size, frequency and flux density.
High temperature applcation dominated mainly by outstanding core loss is not recommended
for continuously proper operation in the circuitries, i.e) higher frequency, comparatively large current
AC chokes.
Continuous operation over 125℃ core temperature may cause permanent damage of insulation of iron
powder itself and coating material. This may cause decrease of inductance and increase of
core loss etc. |
