0805-181J Application Field and Working Principle

Fixed inductors, as their name implies, are electronic components with fixed inductance values. The 0805-181J is a surface mount inductor with a variety of applications. This article will introduce its primary application field and working principle to provide an overview of the device.

Application Field

The 0805-181J is a 0402 (1005 metric) surface mount inductor that is typically used in DC to DC converters, low frequency power supply applications, and on-board power supply designs. It is also used in battery charging circuits and current sensing circuits.

The 0805-181J is also used in various filtering, control, and protection applications. Its versatile design makes it suitable for a variety of applications, including radio and TV receivers, digital music players, and DC to DC converters. It is also widely used in automotive, solar, avionics, and railway applications.

Working Principle

The 0805-181J is a coaxial-style inductor that is composed of a copper cylindrical core and a spiral coil. The core is generally an iron-silicon alloy, while the coil is typically copper wire. Unlike some other inductors, the 0805-181J does not require an external magnetic shield.

The core and coil together form the inductor. When electrical current passes through the coil, a magnetic field is generated within the core. This magnetic field induces an electromotive force within the coil, leading to an increase in the inductor\'s voltage. This effect is known as inductance and it is the reason why inductors are used in various circuits.

The 0805-181J is a polarized device. In other words, there are two leads, one of which must be connected to positive voltage and the other to negative voltage. This is necessary to ensure that the induced voltage is maximized and the device is able to withstand the maximum voltage and current ratings.

The 0805-181J has a rated current of 1.8A and an inductance range of 0.1uH to 220uH. It is also capable of operating at temperatures ranging from -55°C to +150°C with a maximum resonance frequency of 700kHz.

Conclusion

The 0805-181J is a surface mount inductor with a variety of applications. It is primarily used for DC to DC converters, low frequency power supply applications, and on-board power supply designs. The 0805-181J is composed of a copper cylindrical core and a spiral wire coil, and is capable of operating at temperatures ranging from -55°C to +150°C. It has a rated current of 1.8A and an inductance range of 0.1uH to 220uH.
