Fixed inductors form an important part of the electronics industry, playing a vital role in several circuit designs. The PA3790.181HL is one such fixed inductor designed with a specific application in mind. Manufactured by Bourns, this part is designed as an optional accessory for several digital television, set-top box designs, and cable boxes.

The PA3790.181HL is a standard magnetic component constructed using ferrite-based wire material. This part is designed to be an ideal replacement for circuit designs that require inductors with lower current levels and higher inductance. This inductor is composed of two powerful ferrite elements that are secured together, which is necessary to achieve higher inductance levels. The integral magnets allow this part to carry larger current levels without experiencing power loss.

The PA3790.181HL is characterized by its low profile, with a maximum height of 3.25 mm. This part features four power leads that are arranged in two separate positions. Its physical package dimensions are 20 mm x 14 mm x 6.35 mm, and it weighs only 0.4 g. The maximum operating temperature range for this part is 80 Celsius.

The PA3790.181HL has a rated inductance of 181 μH, making it ideal for digital television and set-top box setups. This inductor is designed to ensure steady current flow, thus providing reliable performance in various electronic systems. The PA3790.181HL features a low-current reluctance value, which allows it to be used in applications that require higher inductance values.

The PA3790.181HL has a high-saturation current rating of 6 A, making it suitable for applications that involve heavy current flow. The part also features low temperature coefficients, which helps to maintain steady performance in different operating conditions. Furthermore, this part has excellent self-healing properties, as the ferrite elements have the ability to repair themselves in case of accidental damaging.

The PA3790.181HL\'s working principle is based on the principle of electromagnetic induction, wherein the current passing through an inductor produces a magnetic field which creates voltage in the inductor. This voltage is then allowed to flow through the other power leads to complete the circuit. This working principle allows the PA3790.181HL to regulate current flow and maintain steady power levels in the circuit.

In conclusion, the PA3790.181HL is an indispensable part of the electronics industry, primarily used in digital television, set-top boxes, and cable boxes. This part is characterized by its compact size and low profile, as well as its high inductance and current tolerance. Furthermore, its working principle is based on the principle of electromagnetic induction, allowing it to regulate and maintain steady power flow in different circuits.
