Note*: When ordering, additional ohm resistance notation is recommended.
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 2.54mm+/-1.0mm 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 2.54mm 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/s

, 90minutes. direction x-y z, Amplitude 0.75mm will be applied under break point Frequency (about
60Hz) and 100m/ s
2
over break point
(5) When mounting resistor on heat-sink by screw, clip and pressure strip with using heat conduction grease on back side
of resistor are recommended. Recommended screw torque is 0.5-0.6Nm. In case of screw mount, ISO M3 screw is
necessary, 1/8” screw cannot be acceptable.
(6) Standard packaging is anti-static PE tube, which contains 25pcs / tube.

Pulse Energy Durability
Tentative continuous-pulse power allowance at duty
0.01. Load life test will be necessary in actual
equipment. Because curve will be changed by
resistance, pulse repetition, duty and operating
temperature. Dotted is estimation
