Fixed Inductors

Fixed inductors are passive electrical components that store energy in an electromagnetic field. Usually consisting of a coil of insulated wire, they are most commonly used as part of a radio antenna or a loudspeaker system. The physical size of a fixed inductor is limited by its practical application; therefore, they are often used to form a key component in complex circuits. The ER1641-564KR is a type of fixed inductor. It is a miniaturized, non-shielded, wire wound chip inductor designed for high current applications in automotive and consumer electronics. This inductor is a key component in DC-DC converter circuits, DC-AC inverters, and resonant circuits. The ER1641-564KR is a low profile inductor. It has a clip-on type of Q-factor structure, which is very advantageous for providing high-density inductance and for suppressing copper pattern losses. Additionally, the insulation sleeve of this inductor provides excellent high-frequency performance and an increased temperature range. The primary working principle of the ER1641-564KR is based on Farady\'s Law of induction. This law states that a changing magnetic field induces an electric current in an adjacent conducting material. In the case of the ER1641-564KR, when a current passes through the wire winding of the inductor, an electromagnetic field is produced, which induces a voltage in other surrounding objects. The resulting voltage can then be used to help control circuits or for other purposes. The ER1641-564KR offers excellent frequency characteristics and a high saturation current. It features an operating temperature range of -55 to +105°C, and offers a maximum rated current of 4.8A. Its self-resonant frequency is 1.3GHz, while its inductance is 68nH. In terms of its usage, the ER1641-564KR can be used in a variety of applications where a low profile and high current are important. These applications include DC/DC converters, DC/AC inverters, resonant circuits, high-frequency inverters, radio-frequency circuits, and switching power supplies. Additionally, it is ideal for use in automotive applications and other consumer electronics where size, weight, and cost are considerations. The ER1641-564KR is a reliable and cost-effective inductor, making it a popular choice for a wide range of applications. With its low profile, it is able to offer a wide range of inductances and a high saturation current, making it ideal for a variety of high-current applications. Furthermore, it is highly resistant to EMI and vibration, which adds to its popularity.
