Fixed InductorsInductors are components used extensively in almost all electrical and electronic circuits. A fixed inductor is specifically an inductor which cannot be adjusted by the user once it has been inserted into the circuitry. One of the more commonly used fixed inductors is the CM322522-680KL. This article will discuss the features and applications for the CM322522-680KL, as well as discuss its working principle.The CM322522-680KL is a monolithic, closed-loop, thick film inductor chip with a rated inductance of 680 nH. The chip measures 4.3 mm x 4.3 mm with a height of 0.88 mm and a pitch of 0.2 mm. It features a low DCR of 0.43 Ω (max) and a high SRF of 5.06 GHz (min). It is RoHS compliant and features high power capacity, low profile, high reliability, and a wide operating temperature range for use in a variety of applications.One of the main applications for the CM322522-680KL is for wireless communication systems. This includes cellular phones, RFID, Bluetooth, and Wi-Fi systems. It is also used in high-frequency DC/DC converters, as well as portable computers, notebook PCs, LCD displays, and wireless mouse applications. Additionally, it is used in GPS navigation systems, RF amplifiers, and automotive electronics.The working principle of the CM322522-680KL is based on the principle of electromagnetic induction. This is the production of an electromotive force (EMF) in a conductor or coil due to its movement within a magnetic field. When current passes through the inductor, it produces a magnetic field, which induces a counter-EMF in the coil. This counter EMF is what is referred to as the inductance, and it is measured in henrys (H).The inductance of the CM322522-680KL is measured in nanohenrys (nH) and it is designed so that it is capable of handling high frequencies and high currents. The main features of this chip are its small size, low profile design, and its ability to survive in harsh environmental conditions. Additionally, it features a high current capacity, low DCR, and high SRF.In conclusion, the CM322522-680KL is a highly reliable, widely used fixed inductor chip with a wide range of applications. Its features include a low profile design, small size, high current capacity, low DCR, and high SRF, making it a good choice for use in wireless communication systems, high-frequency DC/DC converters, portable computers, notebook PCs, LCD displays, and wireless mouse applications. Additionally, it is used in GPS navigation systems, RF amplifiers, and automotive electronics. Its working principle is based on electromagnetic induction and its inductance is measured in nanohenrys.
