Additional Details

The VLP5020LT series is designed for automated assembly using standard surface mount technology. It is commonly used in power management circuits for smartphones, tablets, laptops, and other portable electronic devices. The low profile of the inductor makes it suitable for applications where space is limited. The saturation current indicates the current level at which the inductance starts to decrease significantly. It is crucial to select an inductor with a saturation current rating that is higher than the peak current in the application to avoid performance degradation. The 2.2uH inductance value is a common choice for many DC-DC converter designs, providing a good balance between energy storage and transient response. This inductor's construction allows for minimal audible noise during operation.
