Fixed Inductors

Fixed inductors are electronic components that store energy and developed by electromagnetic induction, which can be used in a wide range of applications. Commonly used types of fixed inductors include ferrite bead inductors, helicopter coils, wire wound inductors, and planar inductors. Inductors are one of the essential components of radio frequency (RF) circuits.

ER1025-61JR is a fixed inductor developed by the electronic product manufacturer EPCOS. It is a molded version of a wire-wound inductor, and the inductor coil is encapsulated in an epoxy resin case. ER1025-61JR is suitable for high-frequency, high-current, and low-loss applications.

The ER1025-61JR features a stable inductance from high frequencies up to 250 MHz. Its high temperature performance is remarkable, with an operating temperature range of -30℃ ~ +150℃. It has a high current rating of up to 10A and is capable of handling high power dissipation. In addition, the ER1025-61JR feature good heat radiation, high current capacity, and low DC resistance. With these features, the ER1025-61JR is an ideal choice for high-power applications in various industries.

One of the primary applications of the ER1025-61JR is in RF circuit design. It is used to create a circuit tuned to a particular frequency. It is also used for filtering, for impedance matching, and for signal isolation. It is also used in power conversion circuits such as Switch Mode Power Supplies (SMPS) and DC-DC converters.

The working principle of the ER1025-61JR is quite simple and straightforward. When an alternating current is passed through the inductor, the changing magnetic field induces a voltage in the windings, thus creating an impedance in the circuit. This impedance limits the current flow and enables the control of the power output from the device. This is the principle of operation for circuits such as RF radio receivers, inverters, microwave ovens, and other power electronics.

The ER1025-61JR is widely used in many applications due to its features such as its stable inductance up to high frequencies, high temperature performance, and high current rating. It is one of the most popular inductors for producing high-frequency, low-loss RF circuits.
