►NPF series
NPF are made from alloy powder cores of Fe – Si 6.5, permeability of 26, 60 , 75 , 90 , 125 ui. Better core loss performance by iron based containing 6.5% silicon, small air gaps distributed evenly throughout cores to make excellent DC Bias performance and highly flux density. Major application includes PFC, EMI filter, power supply system smoothing choke, in-line noise filter and buck/boost inductor.

►NPH-H/L
NPH-H & NPH-L are made from alloy powder cores of Fe – Si, permeability of 26 , 60 , 90 , 125 ui. Best core loss and good DC Bias performance by excellent powder quality and self-developed insulation technology. Best Choice for high frequency and space limited application by great molding press and heat treatment manufacture process.
Competitive cost advantages compared to amorphous or Nickel based High-Flux, major application include PFC, output, resonant choke for most Server and IPC power system.

►EQ series
EQ shape mainly made from powder of Fe-Si, larger cross section area can reduce choke size under highly current design. Enclosed magnetic path reduced magnetic leakage get better DC Bias performance. Well thermal reaction by automatic flat winding method, less winding quality issues but more convenient to assemble. Now major application includes DC/DC module, output choke for high power Server system.
