Type ESRH
Solid Polymer Aluminum SMT Capacitors
Solid
Polymer Aluminum
capacitors are now available
with a +125ºC temperature rating. CDE’s type ESRH
capacitors are rated at +125ºC for 1000 hours when
operated at 3/4 of the 105ºC rated voltage. Solid
Polymer Aluminum electrolytic capacitors feature
extremely low ESR which yields a capacitor with very
low high frequency impedance and high ripple current
capability. When low ESR is your requirement,
one type ESRH capacitor can replace three or more
tantalum or aluminum electrolytic capacitors. The
solid electrolyte in a polymer aluminum capacitor
results in a long (and ignition free) life, and the 7.3
x 4.3 footprint is compatible with “D” case solid
tantalum capacitors.

Specifications (continued)
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
(For more information on this product see the Solid Polymer Aluminum Application Guide)
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:
