Fixed inductors, commonly referred to as inductors, store energy in an electromagnetic field, and are widely used in power supplies, switching regulators, radio frequency (RF) circuits, and signal processing circuits. The CM201212-1R0KL, a type of fixed inductor, is a common component in many applications due to its low cost and wide application range. The following sections discuss the application fields and working principle of the CM201212-1R0KL.

Application Fields

The CM201212-1R0KL is a type of fixed inductor with excellent frequency characteristics and is suitable for applications ranging from DC to high frequency/RF circuits. It is most commonly used in EMI/EMC interference protection circuits, such as buck converters, audio filters, cell phone circuits, and others. Its high inductance value allows it to be used for power supply filtering and signal channeling. The CM201212-1R0KL is a surface-mount device and is typically used in space-constrained applications. It also has a wide operating temperature range making it suitable for use in extreme temperature conditions.

Working Principle

The CM201212-1R0KL is a type of fixed inductor, which contains an electrical conductor wrapped around a core. When a current passes through the conductor, a magnetic field is created. This magnetic field generates an opposing voltage, which causes the current to resist change. Therefore, the inductor acts as a measure of current versus time. This relationship can be represented by the following formula: L = ∆I/∆t, where L is the inductance value, ∆I is the changing current, and ∆t is the time period.

The CM201212-1R0KL has a low tolerance rating and robust construction, making it suitable for use in commercial and industrial applications. It also has a high self-resonant frequency, meaning it can respond quickly to changing frequencies in the system. Furthermore, its high saturation current rating allows it to handle larger currents without any significant resistance.
