## Ferrite toroids 

## **RING CORES (TOROIDS)** 

## **Effective core parameters** 

|**SYMBOL**|**PARAMETER**|**VALUE**|**UNIT**|
|---|---|---|---|
|Σ(I/A)|core factor (C1)|0.497|mm−1|
|Ve|effective volume|46500|mm3|
|Ie|effective length|152|mm|
|Ae|effective area|306|mm2|
|m|mass of core|≈220|g|



## **Coating** 

The cores are coated with epoxy, flame retardant in accordance with _“UL 94V-0”_ ; UL file number E 235873. The colour is white. 

Maximum operating temperature is 200 °C. 

## **Isolation voltage** 

DC isolation voltage: 2000 V. 

Contacts are applied on the edge of the ring core, which is also the critical point for the winding operation.
