CR105NP-270MC

Fixed inductors are devices composed of coils of wire and other components that provide an inductance value that remains constant. The CR105NP-270MC is a type of fixed inductor that is typically used in high-power applications such as switching power supplies, resonant converters, and DC-DC converters. This component is also well-suited for use in situations where a steady, accurate inductance value is required.

The CR105NP-270MC is a compact, square-shaped device measuring 10.5 x 10.5 x 8.3 mm, making it well-suited for use in limited space applications. It is a larger-style inductor, and is encapsulated in a molded plastic case. The component measures 9.7 mm in height, and weighs 9.9 g.

The CR105NP-270MC features a large inductance value range, from 15.0uH to 27.0uH. The inductance can be further adjusted with the use of an external air-gap, allowing for greater precision of the inductance value. The device is rated for an operating temperature range of -40 to +105°C and a working frequency between 10 to 300MHz.

In terms of energy storage capacity, the device can hold 745 mJ of magnetic energy, and dissipates an operating power of 4.6 W at 25°C. The device also features a maximum DC current of 6.88 A, and a saturation current of 19.65 A.

The device’s DCR resistance is .062 ohms (typical), and its ACR resistance is between 2-10 ohms (depending on the current testing condition). All of these features of the CR105NP-270MC make it an ideal choice for high-power applications, where steady, accurate inductance values are required.

The core principle of operation for the CR105NP-270MC is based on the well-known laws of induction. The inductor consists of a coil of wire wound around a core material. When electrically energized, the coil creates a magnetic field that “induces” a change in the current. The current flowing through the coil is in opposition to the current energizing the coil, and the magnitude of the induced current is proportional to the rate of change of the current energizing the coil. Thus, when a steady current is provided to the coil, the induced current is zero, and the inductance remains constant.

In applications such as power supplies, the steady current is typically provided by direct current, and the inductor operates as an inductor to store energy. The rate of change of the current through the inductor when it is switched off is proportional to the energy stored. This stored energy is then released to the load in a controlled manner, providing a steady, stable current to the load.

The CR105NP-270MC fixed inductor is an ideal device for those applications seeking to provide a steady, accurate inductance value. Designed for a wide range of applications, from switching power supplies to resonant converters, this component provides a wide range of operating parameters that make it ideal for many high-power applications.
