TYPE ESR SURFACE MOUNT POLYMER ALUMINUM

ELECTROLYTIC CAPACITORS.

Unlike solid tantalum, which can fail short and burn, type ESR capacitors in normal operation fail

benignly as gradual open circuits after 25 to 50 years of operation.

The equivalent series resistance of these capacitors is much lower than for solid tantalum

capacitors, thus you get much higher ripple current handling capability.

recommended for new design, and can be used as replacements to upgrade existing designs that

employ Type ESR capacitors. However, the ESRD, ESRE, and ESRL footprint is not compatible with

the Type ESR footprint.

Specifications:

Type ESR SMT capacitors are polarized, aluminum

capacitors which use a highly conductive solid

polymer as the electrolyte.

They have reliability advantages over both

aluminum and solid tantalum electrolytic capacitors.

Unlike aluminum capacitors, there is no liquid

electrolyte to evaporate and cause failure.

Operating Temperature Range:

-55°C to +105°C at 100% rated Voltage.

Surge Voltage:

125% of the rated working Vdc

Capacitance Range:

4.7uF to 82 uF

Capacitance Tolerance:

±20% at 120Hz and +20°C.

DC Leakage Current (DCL):

After a 2 minute application of the rated voltage at

+ 20°C the DCL is;

4V: < 0.06CV

6.3V - 16V: < 0.04CV or 3µA (whichever is

Moisture Resistance:

After 500 hours storage at +60°C and 90 to 95%

R.H. without load, capacitor will meet the

following limits:

Capacitance change from the initial value shall

not exceed;

+60%/-20% for 4.0 Vdc ratings,

+50%/-20% for 6.3 Vdc ratings,

+40%/-20% for all other ratings.
