These are great little cores. PC40 is a power core material, and has acceptable (but increasing) core losses up to about 150kHz. Beyond this, the core will likely overheat. Most efficient frequency at maximum power handling is about 70kHz.Great for winding your own SMPS transformer. Get some litz wire and yellow tape and you're good to go!Cores are very well packed and I have yet to receive one that was broken during transit.Specs:Initial permeability @ 23°C (µi): 2300Curie Temperature (Tc): >200°cSaturation flux density (Bs): 500mT @ 23°C380mT @ 100°CRemnant flux density (Br): 125mTCoercity (Hc) @ 23°C: 15A/mCore loss (Pcv) @ 25kHz 64mW/cm³ @ 90°C70mW/cm³ @ 100°C@ 100kHz 420mW/cm³ @ 100°CElectrical Resistivity (ρ): 6.5Ω/mDensity: 4.8g/cm³Thermal expansion coefficient (α): 0.000012/KThermal conductivity (κ): 5W/mKSpecific Heat (Cp): 600J/kg•KBending Strength (δb3): 9N/m² * 10⁷Young's Modulus (E): 1.2N/m² * 10¹¹Magnetostriction (λs): -0.000006Core shape: EE42/40/15 (EE4215)Cross sectional area (Ae): 182mm²Effective path lengh (Le): 97mmEffective core volume (Ve): 17600mm³AL value: 4700nH/N²
