HM70-33R75LFTR13

Fixed inductors are electrical components that store energy in the form of a magnetic field, and then release the energy when the electric current changes direction. HM70-33R75LFTR13 is a typical fixed inductor built with radial leaded construction using high-temperature and high-purity Mag-sili Magnetic Silicon Steel. It is the perfect choice for applications requiring high operating temperature range, high current density, low DC resistance, low inductance tolerance and tight-tolerance.

The HM70-33R75LFTR13 has a maximum operating temperature of +179°C, a maximum DC current of 1.3 A, an inductance of 0.3uH ±4%, a rated DC resistance of 0.04Ω and a tolerance of ± 10%. The principle of operation of this fixed inductor is fairly simple. A constant electric current is applied to its electrodes, resulting in a magnetic field being built up within it. This field is then maintained as long as the current remains constant. When the current changes direction, the magnetic field is released as a strong electric current, resulting in the required inductance.

The HM70-33R75LFTR13 is suitable for a wide range of applications, including switching power supplies, voltage regulators, telecom systems, digital point-of-sale systems, medical equipments, and consumer electronics. In switching power supplies, for example, the inductor plays a key role in stabilizing the voltage level. When the switch is turned on, the inductor stores energy in the form of a magnetic field. The efficient release of the stored energy when the switch is turned off is instrumental in stabilizing the voltage level.

The over-specification is a key feature of the HM70-33R75LFTR13. This increases the efficiency of the inductor over time, and allows engineers to design circuits that can handle fluctuating digital loads and temperatures. The device comes with a storage temperature of -40°C to +125°C, and an operating temperature range of -40°C to +179°C. It also features a maximum frequency of 5 MHz, a typical capacitance of 0.0038 pF and a saturation current of 1.3 A.

In conclusion, the HM70-33R75LFTR13 is an excellent fixed inductor for a wide range of applications. It features a high operating temperature range, high current density, low DC resistance, low inductance tolerance and tight-tolerance. It is the perfect choice for applications requiring high-performance inductors with increased efficiency over time.
