  • Applications

  The 1638-26F is a surface-mount, manganese-zinc ferrite core inductor that is designed for use in low-voltage, low-frequency applications. It is commonly used in RF circuits, such as amplifiers, mixers, circuit tuning, impedance matching, and RF attenuators. It is also suitable for use in gyrators and filters. It is small enough to fit into surface-mount circuits where space is limited and can be easily soldered in place.

  The core is constructed from manganese-zinc ferrite material which is very efficient in suppressing losses due to hysteresis and eddy current. The core shape is very compact, making it easy to fit many turns on it, yet still keeping the inductor\'s physical size down. The coil is wound with a thin enamelled copper wire; this is very important for the inductor\'s efficiency in low-voltage, low-frequency applications.

  The 1638-26F is available in a range of inductance values ranging from 10nH to 3300nH, and can handle current ratings up to 1.5A. It has a very low profile of 4.6mm and is rated for operation in temperatures up to +125℃.

• Working Principle

The working principle behind the 1638-26F is that of magnetically coupled coils. When a current is applied to the inductor, an electromagnetic field is created by the current flowing through the coil, which in turn induces a current in the core, creating a magnetic field. This field is then confined within the core, where it can remain in a stable state.

When the current increases, the field intensity increases, causing the core to become saturated. This limits the amount of current which can pass through the inductor, and thus helps to keep the inductance constant over a wide range of operating frequencies. The amount of inductance is also dependent on the number of turns on the coil, as well as the size and shape of the core.

The 1638-26F is a high-quality, high-efficiency inductor which can be used in a wide range of low-voltage, low-frequency applications. It is compact and effective, and is well-suited for use in RF circuit designs, such as amplifiers, mixers, circuit tuning, impedance matching, and RF attenuators. Additionally, it can also be used in gyrators and filters.
