Fixed inductors are electronic components used in circuits to store electrical energy and resist change in current. They are often found in power supply circuits to filter out noise and help stabilize the supply voltage. ER1025-78KR is one of the most popular fixed inductors available in the market. It has a wide range of applications and can be used for a variety of purposes.

ER1025-78KR is an excellent choice for power supply and noise filtering applications. Its size is very small, making it ideal for applications where space is limited. The inductor also has a low DC resistance and excellent current ratings. It can be used in AC circuits as a filter and in DC circuits for switching power supplies and to provide noise suppression.

ER1025-78KR is a high-speed, low-profile, and high-current inductor. It has a rated current of up to 20A and an inductance of up to 11.5mH. It has a peak current of up to 40A and a saturation current of up to 2.5A. The inductor also has a dielectric strength of up to 5KV AC/1KV DC, ensuring better protection and reliability.

The working principle of the ER1025-78KR is based on induction. This means that it can store energy and resist changes in the current passing through it. When current is passed through the inductor, a magnetic field is created that induces a voltage in the windings of the inductor. This voltage is then used to drive the current through the windings of the inductor. As the current in the inductor changes, the magnetic field generated will also change, causing a voltage to be induced in the windings.

In addition, the ER1025-78KR has a high self-resonant frequency, making it suitable for vibration and shock-proofing. It also has a high temperature tolerance of up to 140°C, ensuring better reliability in high-temperature environments. The inductor also has excellent EMI suppression performance, reducing the effect of EMI in sensitive circuits.

The ER1025-78KR is an ideal choice for a wide variety of applications. It is especially suitable for power supply and noise filter applications, as well as for AC and DC circuits. With its low resistance, excellent temperature tolerance, high self-resonant frequency, and EMI suppression performance, the ER1025-78KR can be used in a variety of applications and provide superior performance.
