Fixed inductors are passive devices that are commonly used in electronic circuits. They consist of a coil of wire wrapped around a core material, which can either be air, ferrite, or some other type of metal. These devices can be used to store energy, filter signals, and reduce noise. The PM42S-121 is a type of fixed inductor that is designed for use in high-power, low-voltage applications.

The PM42S-121 is a vertical-mounting, through-hole fixed inductor with a wide range of operating frequencies. It has a rated operating temperature of up to +125°C and a thermal resistance of 200°C/W. The PM42S-121 is designed to be used in various applications, such as DC/DC converters, switched-mode power supplies, battery-charging circuits, and EMI/RFI filters.

The PM42S-121\'s nominal inductance is around 0.12µH, with a maximum DC current rating of 0.9A. It has a minimum DC resistance of less than 0.025Ω and a maximum DC inductance tolerance of ±10%. The device also has a low-profile, and its standard products have an overall height of 5mm.

In terms of working principles, the PM42S-121 operates on the principle of inductance. When a voltage is applied across its terminals, the wire coil stores energy by creating a magnetic field, which induces a voltage (known as self-inductance) in the coil itself. This stored energy is then returned to the circuit when the current flow is reduced or stopped. The amount of inductance is determined by the amount of turns in the coil and the type of core material being used.

In addition, the PM42S-121 can be used to filter signals by using its lumped-element filtering properties. It can be placed in parallel with the circuit in order to suppress lower frequency signals and allow higher frequency signals to pass through. This is useful for EMI/RFI applications, as the inductor can block out unwanted interference and prevent damage to sensitive components.

The PM42S-121 is a reliable and efficient fixed inductor that is designed for a wide range of high-power, low-voltage applications. It has a rated operating temperature of up to +125°C and a thermal resistance of 200°C/W, and its nominal inductance is around 0.12µH. In terms of working principles, the PM42S-121 operates on the principle of inductance, and it can also be used to filter out unwanted signals in EMI/RFI applications.
