Toroidal inductors and transformers are electronic components, typically consisting of a circular ring-shaped magnetic core of iron powder, ferrite, or other material around which wire is coiled to make an inductor. Toroidal coils are used in a broad range of applications, such as high-frequency coils and transformers.Toroidal inductors can have higher Q factors and higher inductance than similarly constructed solenoid coils. This is due largely to the smaller number of turns required when the core provides a closed magnetic path. The magnetic flux in a high permeability toroid is largely confined to the core; the confinement reduces the energy that can be absorbed by nearby objects, so toroidal cores offer some self-shielding.Common Mode Chokes Common Mode Chokes are used when many electrical devices may be connected to the same power lines (or power supply lines) and therefore substantial electrical noise can exist on these lines. Line filters prevent excessive noise from being conducted between electronic equipment and the AC line. Noise is typically common to both lines and in the same direction. Common mode chokes are designed so that common mode current creates a magnetic flux (through mutual inductance) that adds to attenuate the CM noise signal. The normal (differential) mode currents create magnetic flux that ideally cancel each other out so the normal signal frequencies are not attenuated. Any inductance encountered by the differential signal is the result of imperfect coupling of the two coils. Design requirements for a common mode choke It is typical for the inductance value of a common mode choke to be specified as a minimum requirement, thus insuring the crossover frequency is not shifted too high. The frequency range of the interfering signal should be given to allow proper calculation of the attenuation of unwanted signal noise in the design. Proper wire sizing is accomplished by specifying the voltage and current levels across and passing through the common mode choke. Toroid InductorsToroid style common mode chokes are designed to provide the highest common mode impedance over the widest frequency range. These parts are ideal for any application requiring a high DC current bias and are well suited for use in switch-mode power supplies. Common mode chokes are most effective in filtering supply and return conductors with in-phase signals of equal amplitude. Differential mode inductors are available for filtering out-of-phase or uneven amplitude signals.A Toroidal inductor is an inductor that is designed on a doughnut shaped core. Toroidal inductors offer small size, less leakage inductance and lower electromagnetic interference (EMI).Design requirements for a Toroidal Inductors:Typical minimum requirements to be specified for a Toroidal inductor design are: No load inductance in uH Full load inductance in u HDC Current in Amperes AC Current in Amperes peak to peak Operating frequency is needed for core calculations and wire sizing Core material is selected for the known operating frequency or frequencies. Other Toroidal inductor design considerations are space limitations and mounting technique. Lead terminations are also specified through the design of a Toroidal inductor. Pulse TransformerA pulse transformer is a transformer that is optimized for transmitting rectangular electrical pulses--that is, pulses with fast rise and fall times and a relatively constant amplitude.Principle 8 Operating Principles Magnetizing (No-Load) Current Voltage Drop Voltage-Time Product Kickback Voltage Secondary Load Current Effects of Winding Capacitance The Trailing Edge Pulse Distortion The magnetic flux in a typical A.C. transformer core alternates between positive and negative values. The magnetic flux in the typical pulse transformer does not. The typical pulse transformer operates in an “unipolar” mode (flux density may meet but does not cross zero.) Pulse transformer designs vary widely in terms of power rating, inductance, voltage level (low to high), operating frequency, size, impedance, bandwidth (frequency response), winding capacitance, and other parameters. Designers try to minimize parasitic elements such as leakage inductance and winding capacitance by using winding configurations which optimize the coupling between the windings.

Toroidal inductors and transformers are passive electronic components, typically consisting of a circular ring-shaped magnetic core of high magnetic permeability material such as iron powder or ferrite, around which wire is coiled to make an inductor. Toroidal coils are used in a broad range of applications in AC electronic circuits, such as high-frequency coils and transformers. Toroidal round cores offered by us find usage in low tension and high tension transformers and are wound from cold rolled grain oriented (CRGO) silicon steel strips ranging from 10mm to 100mm single slit and we offer core sizes from 15mm ID to 1000mm OD. To provide optimum performance. these toroidal cores are wound by automatic core winding machine and are annealed in high vacuum furnace under protection of nitrogen atmosphere or in continuous tunnel furnace, which results in features like compact volume, light, low magnetic leakage and hum & high efficiency. In CRGO grades required by customer, duly wound and annealed in inert atmosphere.Guaranteed No load current (AT /Cm) as per B-H Curve of particular grade In house testing facilities and 100% testing done on all Toroidal Cores at flux densities specified by customers. Annealing in controlled Nitrogen atmosphere for 18 to 24 hours (at 800° C) Testing for electrical values and issue of test certificates Painting or impregnation (if required) Toroidal Tech Data Toroidal cores can be supplied for use in the manufacture of current transformers, instrument transformers, etc. Typically, such cores are manufactured from grainoriented steel and fully stress relief annealed. Cores are tested to all agreed-upon technical requirements and customer specification flux density. Dimensional the feasibility of any particular combination of dimensions will be verified at the time of an enquiry. Toroidal Cores: Options Shape Round Coating (a) Epoxy edge bonding to fix shape and retain best performance (Recommended for large diameter). (b) Epoxy powder coated to a nominal thickness of 0.025”(Maximum core weight = 5Kg Material used in these cores are prime CRGO electrical steel in grades. M3, M4, M5, MOH, TCH-0, TCH-1, ZDKH. as per customers requirement while ordering specify the inside and outside diameter and strip width in mm.
