<>Fixed InductorsInductors are a fundamental component used in a myriad of applications. The 4470-35H is a fixed inductor suitable for several applications and types of equipment from audio speakers to sound systems and power supplies. It features an inductance of 4.7 mH, a saturation of 370mA, and an impedance of 350 ohms.The 4470-35H is a cost-effective, small, and reliable fixed inductor. It has low loss, low power consumption, is highly resistant to the elements, and has a high surge current rating. It is also suitable for high frequency applications, as it is designed with a high Self-resonance frequency (SRF). Its construction is a ferrite core with copper wire, and it incorporates a cylindrical shape.The 4470-35H has an operating temperature range of -55 degrees Celsius up to +125 degrees Celsius. It is RoHS compliant and ISO-certified, as well as being CEC-certified. It can be used in different industries due to its high-voltage capabilities, high current rating, long life cycle, and surge current rating.ApplicationsDue to its various features and certifications, the 4470-35H has broad applications in many areas. It is used in audio speaker applications, including stereo speakers, sound systems, public-address systems, and television sets. It is also used in electrical circuits where it operates as an element for power filter applications. Apart from its applications in audio speaker systems, the 4470-35H is also used in lighting circuits, switch-mode power supplies, and voltage regulation. Additionally, it is used in power factor correction, high-frequency radio tuners, and transformers. It is also able to be utilized in different DC power lines, as well as audio amplifiers.Working PrincipleThe 4470-35H works by generating a magnetic field when electric current is passed through it. This creates an inductance, which is the resistance of an induction coil to alternating current. It provides a small impedance to the circuit, reducing the current flow. This action allows the inductor to act as a filter, suppressing some frequencies and allowing others to pass.Additionally, the 4470-35H acts as a choke to reduce high-frequency components in the circuit, allowing a signal to pass without much loss of energy. It also operates as a resonance circuit, allowing the current to build up when larger amounts of power are required. This means that the inductor can act as a voltage reducer and smoother in certain applications, allowing the circuit to run smoothly.Conclusion The 4470-35H is a reliable, cost-effective, and small fixed inductor. It has many features and certifications, making it suitable for several applications from audio speakers to sound systems and power supplies. Its working principle is based on generating a magnetic field when electric current is passed through it, resulting in inductance and other filtering effects which contribute to its applications.
