Fixed inductors, such as the 1641R-472K, are electronic components that store electric energy in the form of a magnetic field when a current passes through them. They are used in a variety of different electronics applications such as signal filtering, switched-mode power supplies, power supply filtering, and other circuits. This article will discuss the application field and working principle of the 1641R-472K.

The 1641R 472K is a fixed inductor with an inductance of 470uH. It is designed for surface mounting on PC boards, and it has a maximum operating temperature of +155°C. It has a maximum temperature coefficient of 0.9 %/°C and a 0.3 Ohm maximum DC resistance. It is a low frequency device and is suitable for applications such as boost converters, charge pumps, and power supply filtering for board level products.

In terms of applications, the 1641R-472K is designed for DC-DC power conversion and to be used in DC-DC boost converters. Boost converters provide power conversion from a lower input voltage to a higher output voltage. They are commonly used in power supplies for portable devices such as cell phones and PDAs. The 1641R-472K works as an inductor in the boost converter circuit and helps to ensure that the output voltage is higher than the input voltage.

The working principle of the 1641R-472K involves the flow of current through the inductor. When a current passes through the inductor, it creates a magnetic field, which induces a voltage in the opposite direction of the current. This opposing voltage, known as inductance, counters the voltage from the input source. Depending on the number of turns of the inductor, the size of the resulting magnetic field can be increased or decreased, and therefore the amount of inductance can be adjusted.

In order to use the 1641R-472K effectively, it is important to understand the operating parameters of the device. The maximum operating temperature of +155°C is beyond the normal range of most electronic devices, so special care must be taken to ensure that the device will not be damaged. Also, the 0.9 %/°C temperature coefficient of the device needs to be taken into account in order to ensure that the performance of the device is not affected by the surrounding environment. Finally, the 0.3 Ohm DC resistance of the device should be considered when designing the circuit to ensure that there is sufficient current flowing through the device.

In conclusion, the 1641R-472K is a fixed inductor that is designed for use in DC-DC boost converter applications. The device has an inductance of 470uH, a maximum operating temperature of +155°C, and a 0.9 %/°C temperature coefficient. It also has a 0.3 Ohm maximum DC resistance. In order to use the device effectively, it is important to understand the operating parameters of the device and design the circuit accordingly.
