output voltages ranging from 012V, 5Amp
R-core Transformers are manufactured using the unique rectangular core with round cross section known as R-core. The special feature of this transformer is that the core is gap less and continuous. The winding is done on special round bobbins on two parallel legs of the core.
Design
The core is continuous and gapless, with two balanced windings on either side. The winding is done on special round bobbins on the two parallel legs of the core.
Size
R-core transformers are smaller and have a lower profile than E-I core transformers of the same capacity.
Temperature rise
R-core transformers have a lower temperature rise due to the round cross sectional area and tapered slitting.
Noise
R-core transformers have low noise due to the balanced winding and low flux leakage. This makes them suitable for use in noise sensitive equipments.
Leakage flux
R-core transformers have a leakage flux that is about 1/10th of conventional transformers. This allows the transformer to be placed close to critical electronic components.
Dual c-core output power transformer Dual c-core output transformer is winding with dual c-core, not traditional ei model. Compared with the japanese cut-core, it has more strongly magnetic power than ei-core, the character with no over load distortion is better, the reaction of low frequency is stronger and deeper, so single terminal 300b machine is exploited the dual c-core output transformer.

The range of toroidal transformers can vary in terms of power capacity, voltage, and mounting style: Power capacity: Standard toroidal isolation transformers can range from 100 to 5,000 VA. Voltage: Dual primaries can be configured for 120 V or 240 V operation. Dual secondaries can range from 2 to 12 V windings to 2 to 120 V windings. Mounting style: Standard mounting for sizes up to 5000 VA is with a single metal centering washer and mounting screw or bolt. Other mounting methods include PCB mounting, DIN rail mounting, and resin center potting with brass inserts. Toroidal transformers are known for their high efficiency, typically ranging from 95% to 99%. This high efficiency is due to their near-ideal design, which effectively contains the magnetic flux within the windings, eliminating leakage flux.
They are used in electrical applications when the frequency ranges between 2 MHz to several hundred MHz and are suitable for inductors above 70 Mhz. 3. Sand Dust: These are high-frequency Choke Coils ideally used with ferrites only.
