ER1025-62JR Application Field and Working Principle

Fixed inductors are widely used in power electronics, telecommunications, military industry and other fields. ER1025-62JR is one of the most popular products in the fixed inductor category of Cuiyijia technology.

ER1025-62JR, also known as SMD power inductor, is a type of fixed inductor, with an inductance value of 0.625uH ± 10%. It is an RoHS compliant, low profile, and high temperature SMD inductor for surface mounting with nickel or tin-plated terminals.

Features

ER1025-62JR has many outstanding features. First of all, it has a high outer diameter of 10.0mm, a low profile size of 2.5mm, and a low profile shape that can be applied in a variety of rechargeable device designs. Secondly, its terminals are square and the finished surface is precise, which can easily fit the device. Thirdly, it has a certified insulation resistance of 3000M(DC500V), which ensures high reliability and protection. Last but not least, it has excellent heat and moisture resistance as well as an operating temperature range from -30℃ to 125℃.

Working Principle

ER1025-62JR is an inductor, or choke, that is composed of a wire wound around a core material. When a current passes through the wire, a magnetic field is created in the core material, which in turn generates an opposing voltage known as inductance. This inductance restricts the flow of the current, allowing it to flow only to a certain extent. It also acts as a filter to reduce the amount of noise in the system.

The inductance of the ER1025-62JR is determined by the geometry of the core material, the number of coil turns, and the type of material used. Other factors such as temperature and the rate of change in the current can also affect the inductance, but these effects can be minimized with proper design.

Application

The ER1025-62JR can be used in various types of power applications, such as mobile phones, digital cameras, PDAs, and other small devices. It can also be used in power supply circuits, DC-DC converters, and in other circuits where noise must be suppressed or dampened. As it is a fixed inductor, ER1025-62JR is ideal for use in applications where the frequency of the current remains constant or where the current needs to be kept at a steady level.

It is also useful in applications such as circuit protection, voltage regulation, and voltage step down. ER1025-62JR can also be used in radio frequency interference elimination devices. In applications that require an effective shield against electromagnetic interference, ER1025-62JR can provide a good solution due to its high insulation capacity.

Conclusion

The ER1025-62JR is a highly reliable and cost-effective fixed inductor that can be used in various types of power applications. It has a low profile design, excellent heat and moisture resistance, and a high insulation resistance. With its ability to reduce noise and provide an effective shield against electromagnetic interference, ER1025-62JR is an excellent choice for circuit protection, voltage regulation, and voltage step down applications.
