Round Shape Lightweight Toroid Inductor

Toroid Inductors 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 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).

Specification :

No load inductance in uH
Full load inductance in uH
DC Current in Amperes
AC Current in Amperes peak to peak
Operating frequency is needed for core calculations and wire sizing
The 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 Transformer :

A 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.
