The SPD125R-473M has a wide range of operating temperature, from -40°C to +105°C, making it well-suited for applications in extreme environments.

The working principle of the SPD125R-473M is based on the concept of magnetism. This fixed inductor is constructed using a ferrite core that is wound with insulated copper wire. When a current is applied, a magnetic field is generated around the core that is proportional to the amount of current. This magnetic field links with the coil, creating a self-induction that opposes the flow of current. The amount of induced voltage can be calculated using the following formula: V = -L (di/dt). The voltage induced is proportional to the current and the rate of change of current, which is dependent on the inductance (L) of the coil.

The SPD125R-473M is an excellent choice for those looking for a low-profile, low-cost, and reliable fixed inductor. It is suited for a wide range of applications, from power supply filters to low-noise amplifiers and clock oscillators. Its wide temperature range and reliable performance make it an excellent choice for applications in extreme environments. With its low profile and excellent performance, the SPD125R-473M is an ideal component for those looking for a reliable and cost-effective fixed inductor for their electronic circuit.
