Sumida introduces Class D Amplifier Inductor for LPF: DEP1519B. 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, car audio, home theater and large LCD, etc.
Parts List:
| Part Name | Inductance [Within] (μH) ※1 | D.C.R. at 20℃ max. (typ.) (mΩ) | Saturation Current (A) Max. (Typ.) ※2 |

※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℃)
Production Stage:
