The SRR1260-121K is a power inductor designed specifically for switch mode power supplies. It has an inductance of 1.2mH with a maximum DC current rating of 121A. It has tolerance of +/- 20%. The device is suitable for rated frequencies from 0 to 1.2MHz. It has a minimum thermal resistance of 20C/W. The operating temperature range of this device is from -40 to +85C.
The SRR1260-121K has a multi-winding structure with high mu-metal magnetic shields to reduce interference and keep the device stable and safe. It is made of a high saturation magnetic core material, which makes it suitable for high current and high frequency applications. This device has a small size with low parasitic inductance, making it ideal for use in high frequency converters and power factor circuits.
The working principle of the SRR1260-121K is based on the inductance of two or more windings on a common magnetic core. When alternating current is applied to the windings, a magnetic field is generated, which in turn produces an electromotive force that opposes any changes in current. This provides a stable current path that resists variations, thus ensuring the optimal functioning of the device. As the inductance increases, the impedance to current flow also increases, thus providing a low pass filter effect on any alternating currents.
The SRR1260-121K fixed inductor is ideal for use in a variety of applications including switch mode power supplies, power factor correction, and active rectifier circuits. It can also be used in DC/DC converters, inverters, filter circuits, and general electronic circuits. This device is designed to operate reliably at high temperature and high frequency conditions, making it suitable for applications such as motor drive, solar energy, and automotive systems.
In conclusion, the SRR1260-121K fixed inductor is a reliable and efficient device for a wide range of applications. It has a high-saturation magnetic core material, multi-winding structure with high mu-metal magnetic shield, and low thermal resistance. This device operates reliably at high temperature and high frequency conditions, and has a wide operating temperature range. The SRR1260-121K is ideal for a variety of power supply, inverter, and filter circuit applications.
