Fixed inductors are electronic components that store energy in the form of a magnetic field and are used as inductors in a variety of applications, such as in cellular phones, DC- DC converters, and pulsed-power supplies. The 22R473C is a surface-mount fixed inductor specifically designed to perform these functions in automotive and industrial applications. The 22R473C provides higher power and reliability levels than standard inductor products.The 22R473C fixed inductor is designed for use in circuits with operating frequencies in the range of 100 kHz to 5 MHz. It has an inductance value of 47 µH and a rated current of 3.0 Amps, allowing it to fulfill the requirements of many different applications. The 22R473C uses a ceramic manganese zinc core to ensure excellent heat-transfer properties and superior high-current capability. It also features a high-temperature soldering type, making it suitable for use in demanding conditions.The 22R473C can be considered a hybrid between a traditional, large, porcelain-enclosed, metal-core inductor and a surface-mount passive component. It is designed for use in low- to medium-frequency switching power supplies, switched mode power supplies (SMPS), and DC-DC converters. It can also be used in automotive and industrial applications such as high- power dc to ac inverters, current limiting circuits, and pulse width modulation (PWM) circuits.The 22R473C is ideal for automotive applications due to its wide variety of operating temperatures and current ratings. It can operate at temperatures ranging from -40°C to +125°C, and its 3.0-amp rated current allows it to withstand high voltage spikes generated by electrical devices in automobiles. In addition, its excellent high-temperature soldering capability ensures that it remains firmly attached to the circuit board under the harshest conditions.The working principle of the 22R473C is simple but effective. When electric current passes through the device, it allows a magnetic field to be created around the component, allowing a large amount of energy to be stored in the form of an inductor. As the current is increased and decreased, the magnetic field around the component expands and contracts, allowing the energy stored in the magnetic field to be released at a constant frequency, allowing the device to perform its intended function as an inductor.The 22R473C is a reliable, cost-effective solution for a variety of automotive and industrial applications. It is capable of withstanding high operating temperatures, as well as high current ratings, making it suitable for a wide variety of use cases. Moreover, its simple working principle makes it a convenient solution for many applications and ensures that it will remain a reliable component in the years to come.
