How to classify electromagnetic coils?

Coils can be divided into 4 different types according to different standards： 1. According to the expression of inductance, it can be divided into: fixed inductance, adjustable inductance, etc.； 2. According to the magnetic structure, it can be divided into: air core coil, ferrite coil, iron core coil, etc.； According to the function and function of the inductance, it can be divided into: filter inductance, energy storage inductance, antenna coil, oscillation coil, choke coil, deflection coil, etc.； According to the winding structure, it can be divided into: single-layer coil, multi-layer coil, honeycomb coil, densely wound coil, uniformly wound coil, conductive coil, etc. Label category: Knowledge Bean---Coil Product tags: inductors, coils

Flat wire type high current choke

CRET has launched a new flat wire-wound power inductor with an inductance value of 1~35µH and a saturated DC current of more than 100A DC at 25°C. The new type of power inductor has a compact design, low insertion height, and a thin design based on flat rectangular wire spiral winding technology, which can significantly reduce loss. The new product high-current choke has a DC resistance range of 0.5 mΩ to 15 mΩ and an operating temperature of -40°C to +150°C. It complies with the RoHS directive and is widely used as an output and storage choke in various power supply topologies Circles, including point-of-load power (POL) converters, DC-DC converters, high-current switching power supplies, and inverters used in automobiles and photovoltaic systems. main application Point-of-load power (POL) converter output and storage chokes DC-DC converter and high current switching power supply Inverter for photovoltaic system Automotive applications Main features and advantages The coil is spirally wound with a flat rectangular wire and has a compact size. Large saturation DC current Label Classification: Product Information---Inductance Product tags: PFC inductors, magnetic ring inductors, new energy

Current compensated compact choke

CRET has launched a new series of dual toroidal core chokes with current compensation. The new product can effectively suppress common mode interference. It is available in a variety of sizes. It can provide current handling capabilities from 10 A to 17 A under the rated voltage of 250 V AC (50/60 Hz). The inductance value ranges from 1.0 mH to 6.25 mH, depending on the model. The maximum operating temperature of the choke coil is 70°C. The flame retardant grade of UL 94 V-0 and the relative tracking index grade of CTI600 are used between the base plate and the ring core magnetic core. The epoxy coating also has the same UL flame retardant rating and CTI rating. The magnetic device has excellent current handling capability and is compact in structure. The leakage inductance of the new toroidal core choke products is about 0.4%, which is widely used in switching power supplies, converters and household appliances. It meets the requirements of the RoHS directive and can effectively suppress symmetrical interference. main application Switching power supplies, converters and household appliances Main features and advantages Excellent current handling capability: 10 A to 17 A @250 VAC Compact structure About 0.4% leakage inductance, which can effectively suppress symmetrical interference Label Classification: Product Information---InductanceProduct tags: PFC inductors, magnetic ring inductors, new energy
