Hi - Temperature Range
TTH - SMTTH Series
1.7µF to 2200µF
125V to 6V
-55°C to 200°C
In general the characteristics of the units are the same as the equivalent
TH unit, (see Data Sheet 5007).
It should be noted that only values appearing in this section should be
subjected to a maximum of 200°C, and those appearing in the TH &
SMTH must not exceed 125°C without prior consultation with Arcotronics'
Applications Department.
Leakage currents at the elevated temperatures with appropriate voltage
derating applied are three times the corresponding values at rated voltage
and 85°C.
The TTH & SMTTH series are intended for high temperature operation to
a maximum of 200°C with corresponding derating above 85°C. The
tantalum case design allows a reverse voltage and high ripple current
capability. These series will handle up to 3 volts in reverse at 85°C and 1
volt at 200°C.
The range is of constructional compatibility with the well proven TH &
SMTH range of all-tantalum tubular non-solid electrolytic capacitors,
encompassing many of the values within the TH range approved to CECC
30 202 001 and CECC 30 202 005.

In-Rush Currents
Typical curves showing the current flow during the first 25
microseconds of charging are shown below. Although a very low
impedance source was used (battery), it is likely that circuit
restrictions limited the current flow as currents of the order of 70
amps have been reported from the field for the TH T4 case size.
The TH range may be charged and/or discharged directly across
the terminals with no protective resistor. This is a positive
advantage over the tantalum 'solid' capacitors where protective
resistors must be used to prevent short circuit breakdown by
avalanche effect.
* 150°C, 175°C & 200°C DERATED VOLTAGE IS PEAK VOLTAGE RATING NOT TO BE EXCEEDED.
