High Flux Cores ✉ are manufactured from an alloy powder composed of 50% iron and 50% nickel, making it a high-performance metal powder core material.Among all powder core materials, the High Flux Core offers excellent DC bias performance, a high saturation flux density of up to 15,000 Gauss, low core loss, and high energy storage capability. These characteristics make it particularly well suited for high-power applications with substantial DC bias, including dimming inductors, flyback transformers, line noise filters, pulse transformers, and power factor correction (PFC) inductors.

FAQ
Q: What are the advantages of High Flux cores compared to MPP cores?
A: High Flux cores offer a higher saturation flux density (15,000 Gauss vs. 7,000 Gauss for MPP) and superior DC bias performance, making them ideal for high-current and high-power applications. MPP cores, on the other hand, provide more stable permeability and lower core loss, making them better suited for high-frequency applications.
Q: What material is used in High Flux cores?
A: High Flux cores are manufactured from an alloy powder consisting of 50% iron and 50% nickel, and are therefore also known as iron-nickel powder cores.
Q: What is the operating temperature range of High Flux cores?
A: The operating temperature range is -55°C to +125°C, making them suitable for demanding industrial environments.
Q: What frequency range are High Flux cores suitable for?
A: High Flux cores are designed for medium- to high-frequency applications, typically operating from 10 kHz to 1 MHz, depending on the permeability grade and core size.
Q: What is the difference between High Flux cores and iron powder cores?
A: High Flux cores provide significantly lower core loss, higher saturation flux density, and better DC bias characteristics than iron powder cores. However, they are generally more expensive due to their superior magnetic performance.
