Note:
(1) Insulation material is unnecessary between flange and heat-sink, flange and resistor is separated by alumina substrate.
(2) Resistance measurement shall be made at a point 5.27mm +/-0.6 mm from the resistor body.
(3) TCR of low resistance will be increased as 300ppm/0.02ohm, 200ppm/0.05ohm, 140ppm/0.1ohm and 80ppm/0.2ohm
typically. Testing point is at 5.27mm from bottom of molding of terminals.
(4) Test method is IEC60068-2-6, and specification is sine sweep wave form, 100Hz-2000Hz, 10 cycles, amplitude
0.75mm or 100m/s2, 90minutes. direction x-y z, Amplitude 0.75mm will be applied under break point Frequency (about60Hz) and 100m/ s2 over break point(5) When mounting resistor on heat-sink by screw, clip and pressure strip with using heat conduction grease on back sideof resistor are recommended. Recommended screw torque is 0.5-0.6Nm.
