RELIABILITY AND TEST CONDITIONS
The following test items are satisfied.
(1) Oscillating frequency change: within 0.25%
(2) Resonant resistance change: within 10Ω
(3) Appearance, serious abnormalities not to exist.
SOLDERABILITY
The lead wires are adopted Pb free plating wire to apply Pb free
soldering. You can also use current Sn-Pb eutectic solder.
Test conditions
With Rosin-ethanol 25% by weight,dip in Sn-Pb
eutectic solder bath at 230 5°C for 3 0.5sec. or surface should be
Pb free solder(Sn-3Ag-0.5Cu) bath at 245 2°C
for 3 0.2sec.
