Ultra Low Value, 2-Terminal
When ordering low value resistors please note that the lead
resistance can be a contributing factor. RCD measures the
resistance value at 3/8 ±1/32” from each end of the body (per MIL-R-
49465). If in actual use, a different span from the resistor body to
the PCB will be required, please advise at the time of ordering.
