Fixed Inductors

Fixed inductors are one of the most common components in electronic circuits. They are used to store energy in an inductive field and to provide an electrical path between current carrying elements. The ER1641-752JR is a high-performance, general-purpose fixed inductor which is suitable for a broad range of applications.The ER1641-752JR is a surface mount device with dimensions of 8.9 x 8.9 mm, making it suitable for surface mount applications where space is limited. The inductance value is interchangeable and can be adjusted from 4.0 μH to 10.0 μH by changing the number of turns or incorporating different cores. The inductor is rated for operating frequencies of up to 300 MHz, with a self-resonant frequency up to 700 MHz. The Q factor of the ER1641-752JR ranges between 27 and 40, depending on the inductor value chosen.The ER1641-752JR has a low DC resistance of 0.016 Ω, enabling efficient operation and reduced power loss. The inductor is also able to handle up to 1A of peak current. The ESR of the device is 0.014 Ω, giving it a high current handling capability. The ER1641-752JR is also resistant to temperature changes, with the temperature coefficient over the operating range ranging from -30 ppm/℃ to +40 ppm/℃.The ER1641-752JR has many applications in radio frequency, power control, voltage regulation, and audio frequency circuitry. It is often used in radio receivers, transmitters, audio amplifiers, and other circuits where inductance is needed. It is also used in audio crossover networks due to its high Q factor and ability to handle high currents. In addition, the inductor can be used in DC to DC converters and switching power supplies to reduce input ripple current and filtering AC input interference.The ER1641-752JR works by generating an electromagnetic field when an AC voltage is applied. The number of turns and the core material determine the inductance value of the device. The inductor provides a path for current to flow, and the magnetic field induces a voltage in the inductor as it dissipates energy. This voltage is then regulated by a rectifier and the dissipated energy is converted into a DC voltage.In conclusion, the ER1641-752JR is a high-performance, general-purpose fixed inductor which is suitable for a broad range of applications. The device is able to handle up to 1A of peak current and is characterized by a low DC resistance and a high Q factor. The inductor is mostly used in radio receivers, transmitters, audio amplifiers, and other circuits where inductance is needed. Its operating principle involves generating an electromagnetic field when an AC voltage is applied, and the magnetic field induces a voltage in the inductor as it dissipates energy.
