The word describes the use of iron core inductors feature inductance produced


1, the iron core density distribution has better temperature stability.
2, the core relative to the lower cost of other options.
3, SMD inductor shape can supply flexibility and variability when necessary, but higher costs.
4, while the SMD power inductors are usually seen in the use of high magnetic power DC / DC converter circuit.
5, another performance tradeoffs can be seen in the inductor current, the inductor voltage (pin 14 to pin 16) and the output voltage ripple typical waveform.
6, the use of smaller inductance inductance fdv0620-0.47μh produce higher peak current, the output voltage ripple below 18mv peak to peak.
7, SMD inductor peak to peak ripple generated just over 12mv. Peak current charges the output capacitor and supply the load current.
8, on the inflow and outflow of a large capacitance current, which will result in higher output voltage ripple.
9, chip inductors used for power supply filtering circuit inductance is focused on energy storage element suppressed conductivity interference.
10, SMD power inductors in the PCB circuit devices will be extensive use of inductive components and EMI filter components.
11, PCB board circuit electronic devices will be extensive use of inductive components and EMI filter components, PCB board circuit electronic devices will be extensive use of inductive components and EMI filter components.
12, in the circuit, the inductor must have a high Q, narrow inductance variation, stable temperature coefficient of the resonant circuit in order to achieve a narrow band, low-frequency-temperature drift requirements. A high Q resonant circuit having a sharp peak.
