Area Product (Ap)

2743.97 cm⁴

Core Volume

1274.2 cm³

Design Notes

Flux Density Selection:

Use 60-80% of Bsat for reliable operation
Lower B reduces core loss but increases size
Higher B risks saturation under transients

Current Density Guidelines:

2-3 A/mm² for natural convection
4-6 A/mm² with forced air cooling
Higher values require derating or cooling

Core Material Selection:

Silicon steel: 50/60 Hz power transformers
Ferrite: High frequency (10 kHz - 1 MHz)
Amorphous/Nano: Low loss, high efficiency
