## Toroids (5943000601) 

Part Number: 5943000601 

43 TOROID 

## Explanation of Part Numbers: 

– Digits 1 & 2 = Product Class 

– Digits 3 & 4 = Material Grade 

– 9th digit 1 = Parylene Coating, 2 = Thermo- Set Plastic Coating 

**A ring configuration provides the ultimate utilization of the intrinsic ferrite material properties. Toroidal cores are used in a wide variety of applications such as power input filters, ground- fault interrupters, common- mode filters and in pulse and broadband transformers.** 

All toroidal cores are supplied burnished to break sharp edges. 

## Coating Options: 

– Toroids with an outside diameter of 9.5 mm (0.375″) or smaller can be supplied Parylene C coated. The Parylene coating will increase the “A” and “C” dimensions and decrease the “B” dimension a maximum of 0.038 mm (0.0015″). The ninth digit of a Parylene coated toroid part number is a “1”. See reference tables for the material characteristics of Parylene C. Parylene C coating is RoHS compliant. 

– Toroids with an outside diameter of 9.5 mm (0.375″) or larger can be supplied with a uniform coating of thermo- set plastic coating. This coating will increase the “A” and “C” dimensions and decrease the “B” dimension a maximum of 0.5 mm (0.020″). The 9th digit of the thermo- set plastic coated toroid part number is a “2”. Thermo- set plastic coating is RoHS compliant. 

– Thermo- set plastic coated parts can withstand a minimum breakdown voltage of 1000 Vrms, uniformly applied across the “C” dimension of the toroid. 

## **For any toroidal core requirement not listed in the catalog, please contact our customer service department for availability and pricing.** 

The C dimension may be modified to suit specific applications.
