(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 circ uit, rmp10s (smd) or lead form ed rnp10s are prepared, rnp10s or rmp10s are screw mount style. when solder ing mount is better, please use rmp20s. (6) at resistance from 220 to 51kohms rating power shall be restricted in 10w. lead free
