DERATING CURVE AND TEMPERATURE RISE

NOTES

1/ Insulating material will not be used between flange and resistors, because flange and
resistor are separated by an alumina substratUsing heat conduction grease on the surface
of the flange is recommended.
2/ Heat resistance between resistor and flange is 3.6K/W, attention to thermal design should
be observed as the resistor temperature should be kept under 155C in operation.
3/    0.1% tolerance resistors are available, please enquire.
4/ For RF application circuits, lead formed TNP10S--Z10(smd) can be prepared, TNP10S---Z10
are screw mount style.
5/  At resistances from 220 to 51kohms power rating shall be restricted in 10W.
6/  Standard packaging is RoHS PS/PE tube packaging, which contains 50pcs/tube.  When
ordering, noting tube or tray type packaging is recommended.
