Fixed inductors are electronic components used in electronic circuits to store electrical energy in the form of an electromagnetic field. Their use in electronic circuits is mainly to either increase or decrease the flow of electricity through the circuit (attenuation or boost). Inductors work on the principle of Faraday’s Law of Induction, which states that “A changing magnetic field produces an electric field”.

CDR105BNP-680LC

The CDR105BNP-680LC is a single, compact, fixed inductor that is specifically designed for use in low frequency DC-DC converter circuits. It has a low equivalent series resistance (ESR) and inductance of 0.1µH, making it suitable for applications that require a high-current, low-loss output. This inductor is also temperature and shock resistant, allowing it to stand up to even the most rigorous industrial environments.

The CDR105BNP-680LC is designed with an open air core, which allows for a higher current density relative to other fixed inductors on the market. Additionally, the open core design reduces the flux in the core, resulting in lower losses and better efficiency. Its epoxy-potted design also prevents moisture or mechanical damage from affecting the inductor’s performance

Application Field and Working Principle

The CDR105BNP-680LC is primarily used in low frequency DC-DC converters, due to its high current and low ESR. This inductor is also ideal for applications where a high inductance value is needed but space is limited. Additionally, this inductor is useful in circuits that require low operating frequencies (<200kHz).

The CDR105BNP-680LC works on the principle of Faraday’s Law of Induction. As current flows through the inductor’s coil, a magnetic field is generated. This magnetic field then interacts with the coil, inducing an electric field. This electric field opposes the current, limiting the amount of current that can flow through the coil and creating what is known as an inductance. Therefore, the CDR105BNP-680LC acts as a fixed inductor, allowing for a controlled flow of electric current through the circuit.

In addition to its use in DC-DC converters, the CDR105BNP-680LC can also be used in EMI (Electromagnetic Interference) suppression, power filters, RFID (Radio Frequency Identification) shielding, and other electromagnetic radiation applications, due to its low ESR and high inductance value.

In summary, the CDR105BNP-680LC is a low ESR, high current, fixed inductor that is designed for use in low frequency DC- DC converters. This inductor is also temperature and shock resistant and can be used for other applications such as EMI suppression and RFID shielding, due to its low ESR and high inductance value.
