Fixed inductors are passive electronic components that store energy in the form of a magnetic field when the electrical current is passed through them. PM3308-680M is one type of such inductor that has a wide range of applications mainly in AC/DC power supply,SMPS,telecom, DC/DC converter, digital circuit and energy-harvesting converters. It comprises of a nonstandard EP13 core type and an inductance range of 0.68 to 6.8 µH. It is composed of hight temperature-resistant plastic mechanism and adopts electroplating technology. This technology enforces the mechanism with a strong abrasion and corrosion resistance, which enables him to work well even in high temperature and moist environment.

PM3308-680M is designed with a wide operation temperature range from -40 to +130℃ to meet various temperature requirements. It also utilizes an epoxy resin, which increases the power dissipation, reduces the temperature rise and decreases the EMI effects. This epoxy resin contains a strong adhesive for greater sealing and softening properties so as to reduce the airborne noise transmissions and reduces the impact on other levels of the electronic system. Additionally, it has a high efficiency and noise reduction, and it helps to increase the system’s reliability.

The working principles of PM3308-680M are based on the inductor’s relative inductance. Inductance is the ability of the component to resist changes in electrical current through it. Therefore, when a changing voltage is applied to the inductor, an electron field is generated within the inductor, resulting in current flow. This electron field then creates a magnetic field inside the inductor, and this magnetic field stores the energy of the circuit. The level of inductance is determined by the size and shape of the inductor’s core material, as well as its winding. The higher the inductance value, the lower the current that is allowed to pass through the inductor.

Furthermore, PM3308-680M utilizes high purity materials, such as iron aluminum and cobalt, to be able to tolerate thermal shock and improve conductivity, stability, and reliability. Its excellent performance in reducing the voltage noise, interference radiation, and EMI effect makes it suitable not only for power supply but also for digital circuit and telecom. In addition, it is a great cost-effective option compare to other products. With its low profile and non-magnetic shield, it can also offer both safety and quality, which make it a widely used electronic components.

In conclusion, PM3308-680M is one type of fixed inductors with a wide range of applications, namely in AC/DC power supply, SMPS, telecom, DC/DC converter, digital circuit and energy-harvesting converters. It utilizes hight temperature- resistant plastic mechanism, electroplating technology, epoxy resin and high purity materials, to ensure an excellent performance in reducing the voltage noise, interference radiation and EMI effect. Its ability to tolerate thermal shock and its cost-effectiveness make it a great option for electronic components.
