Fixed Inductors are essential components in all types of electrical circuits. They store energy in an inductive field for both magnetic and electro-acoustic applications. There are a variety of inductor designs ranging from simple wire wound types to current limited "Smart" technologies. One of the most popular types of fixed inductors is the VLS4012T-3R3M1R2.

The VLS4012T-3R3M1R2 is typically used in voltage-regulating power supplies, audio systems, RF transmitters and receivers for aerospace and defense applications, and also transformer and motor starter applications. It is designed to filter high frequency noise and reduce power consumption. It is also designed to provide high inductance values in a small, surface-mount form factor, making it suitable for a wide range of applications.

The VLS4012T-3R3M1R2 employs a core-type construction with a high saturation current rating of 3A, a low resistance of 0.3 ohms, and a maximum inductance value of 3.3mH. It also features a robust construction with an operating temperature range of -55°C to 110°C. This makes it an ideal choice for applications such as power conversion and filtering, RF transmission and reception, motor drive circuits, and switching power supplies.

The VLS4012T-3R3M1R2 uses a toroid-type core which is wound with a thick enameled copper wire. The winding arrangement is designed to reduce inductance loss due to eddy current and inductance temperature variation. The shielding provided by the winding arrangement also helps to reduce common mode noise.

When an AC voltage is applied to the VLS4012T-3R3M1R2, the core of the inductor becomes magnetized. This induces a current flow in the winding which will oppose the changes in the AC voltage, limiting the rate of change and effectively filtering out any high frequency noise or spikes. The AC voltage is then converted into a DC voltage which is then stabilized and regulated by the inductor.

The VLS4012T-3R3M1R2 is a great choice for applications that require high inductance values in a small form factor, as it offers a variety of benefits such as high saturation current rating, low resistance, high frequency noise filtering and power consumption reduction. It is also designed to handle high temperature environments, making it a reliable and robust component.
