Jan 13th, 2023, Shenzhen-CODACA, the global leading high current power inductor manufacturer, has launched a digital amplifier power inductor CPD2320S and CPD3119SA series. They are designed for digital amplifiers to solve the problems of heating, noise, and poor sound quality. CPD2320S and CPD3119SA series digital amplifier power inductor are widely used in high-frequency applications such as Hi-fi amplifiers, AV receivers, home theater systems, powered speakers, musical instrument amplifiers, etc.

Mn-Zn ferrite cores with high magnetic permeability and excellent transmit electromagnetic signals.

THT high current power inductors CPD2320S and CPD3119SA series are designed with a Mn-Zn ferrite cores with extremely low magnetic core loss and excellent linearity of the saturation current curve. These high-current ferrite power inductors are less affected by temperature and are less prone to magnetic saturation under peak current conditions, effectively filtering out spike noise.

The coils of the CPD2320S and CPD3119SA series are wound with litz wire, which can effectively reduce the AC loss at high-frequency and reduce the communication loss caused by the skin effect. They have better temperature stability and the operating temperature is -40℃~125℃ , ensuring high efficiency and sound quality of digital amplifiers.

Environment Standard

CPD2320S/CPD3119SA series features RoHS, REACH-compliant, Halogen-Free.
