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 2c and the humidity of 9095%, 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.
