Type ESRH Solid Polymer Aluminum SMT Capacitors
Typical Impedance & ESR
Life Test:
Apply rated DC working voltage at 105 ºC (or
0.75 x WVDC at 125 ºC) for 1000 hours, and
then stabilize them to +20 ºC. Capacitors will
meet the following limits:
∆
C = ±10% of the initial measured value
DF & DCL ≤ the initial specified value
Shelf Life Test:
Shelf life is typically 5 to 10 years. Accelerated test:
after 500 hours at125 ºC, capacitors will meet the
following limits after stabilization at 20 ºC:
∆
C = ±10% of the initial measured value
DF & DCL ≤ the initial specified value
Moisture Resistance:
After 500 hours storage at +60 ºC and 90% R.H.
without load, the capacitor will meet the following
limits:
∆C = +70%/–20% of the initial measured value
(2.0 & 2.5 Vdc),+60%/–20% of the initial
measured value (4.0 Vdc), +50%/–20%
of the initial measured value (6.3 Vdc),
+40%/–20% of the initial measured value
(8.0 Vdc).
DF ≤ two times the initial specified value
DCL ≤ the initial specified value
Resistance to Soldering Heat:
Capacitors withstand being heated in an oven at
235 ºC for 200 seconds.
Soldering:
Solid Polymer Aluminum capacitors are designed
for reflow soldering.
Preheat the capacitors at 160 ºC for a maximum of
120 seconds. The time at or above 200 ºC on the
surface of the capacitor should be per the
following chart:
