Fixed Inductors

Fixed inductors can be categorized as either RF inductors, choke coils, transformer coils, or antenna coils. Each of these inductors serve a specific purpose, and range in size from a few hundredths of an inch to several feet. They are usually categorized by their maximum impedance where lower impedances create signals with higher frequencies, and higher impedances create signals with lower frequencies.The 4307R-225H is a specific type of inductor known as an RF inductor. RF inductors are typically used in radiofrequency (RF) and microwave communication systems for signal filtering, impedance matching, frequency control, tuning, and circuit stability. This particular RF inductor is specifically designed for high frequency (HFF) and very high frequency (VHF) applications, as its inductance value is relatively small.The 4307R-225H is a low cost, high-performance inductor that provides reliable high-frequency performance. Its general construction is an air-core which prevents the generation of unwanted harmonics and distortion. The air-core also eliminates large unwanted losses due to the absence of high-Q (Quality Factor) dielectric materials. Its primary purpose is to filter out RF signals and provide stable transmission.The 4307R-225H’s coil is wound from copper wire to enable current and voltage to pass through with minimal resistance. Its maximum inductance is225H and its impedance is 4307R. Its inductance value indicates that it is capable of handling high frequencies in therange of up to 500 kilohertz. Additionally, its impedance indicates that it provides resistance against high frequencies and is suitable for HFF and VHF applications.The 4307R-225H’s coil is generally enclosed in a metal case to protect the internal components from external interference. It also features an epoxy bonded bobbin core which helps in reducing radiated emissions and further protects the unit from mechanical and electrical stresses. Its bobbin is also corrosion resistant and has a long service life.Overall, the 4307R-225H is a reliable, high-performance inductor that is suitable for a variety of high-frequency applications. Its low-cost and robust construction make it ideal for use in consumer electronics, automotive, medical, and military equipment. It provides excellent signal filtering capabilities and is capable of handling high frequencies, making it a versatile and well-suited inductor for this type of application.
