Aluminum Oxide Ceramic
Aluminum oxide insulating washers have a dielectric strength of approximately 21.7 x 10
for .76mm material (550 volts/mil for 0.030 inch materail) and 16.9 x 10
(430 volts/mil for 0.062 inch materail). The thermal conductivity of aluminum oxide is 15.06 W/mK at 75°
(167° F) [8.71 BTU/hr-ft° F].
Aluminum oxide has unique thermal conductivity qualities and features low loss factors at high frequencies. It
has high compressive strengths, high volume resistivity, low thermal expansion and it resists radiation.
Note: Hole diameters are +/- .13mm (.500"), angularity is +/- 1° and flatness is .05mm (.002") TIR unless
otherwise specified.
For TO-3
*Thickness:
4103: 1.78 (0.070) to 2.03 (.080)
4104: 1.52 (0.060) to 2.03 (0.080)
For TO-220
*Thickness 1.57mm +/- 0.08 (0.062" +/- 0.003"); surface flatness is 0.10mm
(0.004") TIR
**Thickness 1.78mm +/- 0.25 (0.070" +/- 0.010")
For TO-218, TO-247, and TO-3P
