Fixed Inductors
Fixed inductors are devices that store energy in a magnetic field when electric current passes through them, releasing it when the current flow is reversed or interrupted. The CDR7D28MNNP-8R0NC is one such type of fixed inductor, which is a surface mountable device designed for use in electronic circuits. It is a multi-layer molded type inductor with two capacitors for increased output current and a ferrite core for improved stability. The CDR7D28MNNP-8R0NC is also known as a “DC inductor” because it works in circuits that require direct current such as DC-DC converters and inverters.
Application Field of the CDR7D28MNNP-8R0NC
The CDR7D28MNNP-8R0NC is commonly used in power electronic circuits, particularly in DC-DC converters, inverters, and switching power supplies. It is suitable for use in a wide variety of applications, from small cell phone chargers and wall warts to large industrial AC/DC converters. The device can take up to 2.8 amperes of current, making it suitable for use in circuits involving higher power levels. Its ferrite core gives it excellent properties for filter and step-up designs.
Due to its small size and surface mountable construction, the CDR7D28MNNP-8R0NC is well suited for use in high density electronics, such as Printed Circuit Boards (PCBs) used in mobile phones, tablets and other digital products. The device has excellent thermal behavior, making it suitable for hot-spot conditions and reducing the need for additional insulation. Additionally, the CDR7D28MNNP-8R0NC is UL recognition, making it well suited for use in commercial and industrial applications where safety is a must.
Working Principle of the CDR7D28MNNP-8R0NC
The CDR7D28MNNP-8R0NC is based on Faraday’s law of induction. When a current passes through the coils of the device, an AC flux is generated within the ferrite core, inducing an opposing current in the coils. This opposing current is known as counter EMF and it is used to oppose the current flow, decreasing its magnitude. In this way, the total current flowing the system is reduced. The amount of current reduction is determined by the electrical properties of the device and the ambient conditions that the device is operating in.
The two capacitors used in the CDR7D28MNNP-8R0NC are connected in parallel to the inductor, forming a resonant circuit. When a current is applied to the device, the applied voltage is applied to the capacitors in opposite polarity, generating an oscillating electric field. This oscillating field works to allow the inductor coils to store energy more efficiently, improving the overall efficiency of the device.
The CDR7D28MNNP-8R0NC is also designed to minimize emissions of electromagnetic radiation. This is done by wrapping the coils of the device in a special material which is designed to absorb and dissipate the emitted radiation. This helps to reduce interference caused by these types of devices, making them suitable for use in crowded environments such as industrial machinery or consumer electronics.
Conclusion
The CDR7D28MNNP-8R0NC is a multi-layer molded type inductor with two capacitors and a ferrite core. It is suitable for use in power electronic circuits, particularly in DC-DC converters, inverters and switching power supplies. The core of the device is designed to store energy more efficiently, improving its efficiency, while the special absorbent material helps to reduce emissions of electromagnetic radiation. The CDR7D28MNNP-8R0NC is a high performance, reliable and safe device suitable for commercial and industrial use.
