Breakdown voltage

 

Test method:JIS C 2110

　Step up voltage at a rate of 500V a second up to breakdown.

Test piece size (Thickness)

　Aluminum plate=1.5mm,　　Insulation layer=120μm,　　Cu foil=35μm

Test condition

　Negative electrode=Alumimun plate　　Positive electrode=Cu foil(25mmφ)

　Impressed current =AC 　Leakage current=10mA
The above shows that AD-7200TY could withstand voltage up to　5600V on average even if it is very thin of 120μm.

 

Long term reliability

 

< 175℃ for 3000 hours >

The above shows the test result of AC-7200TY which AD-7200TY is coated as insulation layer on Aluminum plate's surface.Both Breakdown voltage and Peel strength are strong enough even after heat treatment of 175℃ for 3000 hours.

 

< -65℃ ⇔ 125℃ × 3000-cycle　>

The above shows the thermal cycle test result of AC-7200TY. Both Breakdown voltage and Peel strength are strong enough even after 3000-cycle of -65℃⇔125℃ .
