The WLPN303015M3R3PB is a thin film resistor SMD power inductor manufactured by Walsin. It boasts a 303015 3.3uH ±20% tolerance, meaning the inductance of the inductor can vary by up to 20% from its stated value. This makes it ideal for applications such as DC-DC power converters, resonant converters, RF stages, clocks, and other power management systems. It also has a low internal resistance, allowing it to achieve high efficiency and low power loss. Walsin also offers a wide selection of other thin-film resistors and SMD power inductors with different power, inductance, and tolerance ratings.
