Class D Amplifier Inductor for LPF: DEP1519B

23 Januar 2019

DEP1519B is featured with high current power supply and low DC resistance. This Inductor is wound by flat wire and assembled with the Mn-Zn ferrite core. The L value range is the same as the existing type DEP1519.

Key Features:

  • Ferrite core construction
  • Magnetically shielded
  • Operational Temperature range: -40°C ~ +125°C (including self-heating)


Applications:

Digital amplifier filter, home theater and large LCD, etc.

※1 Measured frequency Inductance at 1kHz, 1V.
※2 Saturation current: This indicates the value of D.C. current when the inductance becomes 25% lower than its initial value.
※3 Temperature rise current: The value of D.C. current when the temperature of coil becomes △T=40℃. (Ta=20℃)
