Magnetics’ toroids, whether Powder Core, Ferrite, or Tape Wound, are offered with coatings that make winding easier, improve voltage breakdown, add breakstrength and provide a tough, wax tight, moisture and chemical resistant barrier.
Magnetics Coatings for Powder Cores
| Coating Code | Color | Voltage Breakdown Minimum | Temperature Rating | Type of coating |
| A2 | Varies | 500 V | Up to 200 C | Standard Epoxy MPP and High Flux Coating |
| A7 | Varies | 500 V | Up to 200 C | Standard Epoxy Kool Mu and XFlux Coating |
| AY | Clear | 300 V | Up to 130 C | Standard Parylene Coating |
| A5 | Varies | 1000 V | Up to 200 C | Increased GVB Epoxy |
| A9 | Varies | 4000 V | Up to 200 C | Increased GVB Epoxy |
| D4, L6, M4, W4 | Varies | 500 V | Up to 200 C | Temperature Stabilization Coatings for MPP |
*Varies by material: MPP – Grey, High Flux – Khaki, Kool Mu – Black, XFlux - Red
Magnetics Coatings for Ferrites
| Coating Code | Color | Voltage Breakdown Minimum | Temperature Rating | Type of coating |
| V | Grey | 1500 V | Up to 155 C | Nylon |
| Y | Clear | 1000 V | Up to 130 C | Parylene |
| Z | Grey | 1500 V | Up to 200 C | Epoxy |
Nylon offers superior solvent resistance compared to epoxy
