The resistive element comprises a thin film of nickel-chrome alloy
evaporated onto a high thermal conductivity ceramic element. Metal end
caps are force fitted to the element prior to spiralling to value. Tinned
copper lead wires are welded to the end caps and the components are then
coated. One coat of phenolic resin is followed by three coats of epoxy resin.
All resistors are tested for value and tolerance.

Metal Film Fixed Resistors
Storage Condition (MSL1)
The performance of these products, including the solderability, is guaranteed
for a year from the date of arrival at your company, provided that they
remain packed as they were when delivered and stored at a temperature of
25°C ± 5°C and a relative humidity of 60%RH ± 10%RH
Even within the above guarantee periods, do not store these products in the
following conditions. Otherwise, their electrical performance and/or
solderability may be deteriorated, and the packaging materials (e.g. taping
materials) may be deformed or deteriorated, resulting in mounting failures.
1. In salty air or in air with a high concentration of corrosive gas, such as Cl2,
H2S, NH3, SO2, or NO2
2. In direct sunlight
