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:
