Notes
(1) Insulating material will not be used between flange and resistors, because flange and resistor are
separated by alumina substrate.
(2) Using heat conduction grease on surface of tab is recommended.
(3) Heat resistance between resistor and tab is 3.6K/W, heat design will be performed as resistor
temperature shall be under 155 C in operation.
(4) 0.1% tolerance resistors are available, please call factory.
(5) For application to r-f circuit, RMP10S (smd) or lead formed RNP10S are prepared, RNP10S or
RMP10S are screw mount style. When soldering mount is better, please use RMP20S.
(6) At resistance from 220 to 51kohms rating power shall be restricted in 10W.
