Fixed Inductors are electrical components used to build inductors or coils. They’re used in electronic circuits to create signals or reduce noise in a narrow frequency range. They’re also used in radio receivers and transmitters to filter different frequencies. One example of a Fixed Inductor is the DR1040-3R8-R. It\'s a through-hole component with a radial lead, which can be soldered onto a PCB (Printed Circuit Board). The material of the inductor is ferrite, which is a type of highly magnetic material. It is used to reduce electromagnetic interference (EMI) and to create a wide range of special inductance values in the range of 0.01µH to 4.7mH. The DR1040-3R8-R has a maximum DC current of 110mA and a saturation current of 44mA. Its maximum allowable voltage is 25V, and its impedance is 84 ohms with a vibration resistance of 80MΩ at 40 shakes/minute. The inductor is rated for a maximum of 2W of power dissipation, and its temperature coefficient is +/– 10%. The DR1040-3R8-R application field is extensive. It is useful for choke filters, pulse transformers, voltage regulator circuits, ballast for LED lighting, and a EMI filter for automotive systems. Additionally, it can be used in cellular phone circuits and can also be used for TV and video game consoles. The working principle of the DR1040-3R8-R is based on the law of induction. When a current passes through a conductor, it gives rise to an electromagnetic field. This field is used to induce a secondary current in the circuit. This induced current is proportional to the rate of change of the circuit’s magnetic field. The DR1040-3R8-R provides a relatively steady inductance as current passes through it, while the inductance value may become unpredictable under heavy saturation, leading to power losses in some cases. The DR1040-3R8-R is both heat and vibration tolerant, making it suitable for a wide variety of applications. The inductor has a low DC resistance, allowing it to operate at lower temperatures and higher frequencies. Finally, its nonmagnetic shielding layer helps to protect it in hostile environments such as automotive systems. The DR1040-3R8-R provides a stable inductance over a wide voltage and current range and is insensitive to temperature and magnetic fields, making it highly suitable for those applications that require a reliable inductor. It\'s also extremely versatile, as it can be used in a wide variety of fields such as in automotive systems, cellular phones, LED lighting, and TV or video game consoles. As a result, the DR1040-3R8-R is an ideal choice for those looking for a versatile and reliable inductor.
