Fixed inductors are electrical components that store energy in the form of a magnetic field. These components are used in circuits where a stable current is needed or an external magnetic field needs to be generated. The SP1210R-823H is a fixed inductor developed by the electronics company Sanyo. It is a small chip-shaped component with a size of less than 10mm x 10mm. This device is commonly used in power management circuits, where current needs to be regulated and filtered.

The SP1210R-823H uses the concept of self-inductance to regulate and filter current in its application field. If an alternating current passes through a winding around a core, self-inductance is produced. The induced voltage opposes the applied voltage, so that the electrical current passing through the coil is controlled. This principle is used to ensure that only the desired amount of current is passed through the inductor.

Different layers of coils are used in the SP1210R-823H to increase its self-inductance, enabling it to effectively regulate current at different frequencies. The inductance is also adjustable to meet requirements from the circuit design. The internal structure of the device is made up of a monolithic ceramic element with winding. The electrical connections of the device are made with nickel-plating copper wires, which help to reduce contact resistance.

The SP1210R-823H has a maximum working current of 100mA and a direct current resistance of 0.5 ohms. It has a high-temperature capability of up to 125°C and a typical current leakage of up to 0.2mA. Additionally, this device has excellent temperature characteristics and is able to retain its inductance value even in extreme temperatures.

The SP1210R-823H is mainly used in power management circuits, but can also be used in high-frequency circuits. The device is commonly used to filter out noise, reduce power consumption, and convert alternating current into direct current. Additionally, it can be used to protect other components in the circuit from overvoltage or overcurrent.

In conclusion, the SP1210R-823H is a fixed inductor developed by Sanyo. It uses self-inductance to regulate and filter current in power management circuits, and it can also be used in high-frequency circuits for noise reduction and power conversion. This device is made up of a monolithic ceramic element with winding and has a maximum working current of 100mA and a direct current resistance of 0.5 ohms. It has excellent temperature characteristics, enabling it to retain its inductance value even in extreme temperatures. This component is commonly used to protect other components in the circuit from overvoltage or overcurrent.
