MOR 2WSS Metal Oxide Film Resistor

Metal Oxide Film Resistor YZPST-MOR-2WSS-3K3-J The resistors arrayed are placed into a constant temp. humidity oven at the temp. of 40 ±2°c  and the humidity of 90~95%, then rated power is applied for 1.5 hours and cut off  for 0.5 hour. The similar cycle will be repeated for 500+24 -0 hours in total (including cut-off time). Then remove the voltage, taking the resistors out of the oven and leaving them at room temp. for one hour. The resistance value change rate between pre-and- post test shall be within ±5%. There also shall be no evidence of remarkable change on appearance, and the marking shall not be illegible.   TYPE   L    4   D t   H:t:3 d:t0.1   ResistanceRange   MaxWorking   RSU   1W   6.8 2.6:t0.5   28   0.6   0.220-1MO   350V   2W   9   3.5   28   0.8   220-1MO   500V   3W   15   5   28   0.8   O.220-1MO   750V   Steps Temperature(k) Time (minutes) 1st step -55 ± 3 30 2nd step Room temp. 3 3rd step 155 ± 3 30 4th step Room temp. 3        7.6 Moisture-proofLoad Life:           The resistors arrayed are placed into a constant temp./humidity oven at the temp. of 40            ±2°c  and the humidity of 90~95%, then rated power is applied for 1.5 hours and cut off
