    9. WORKING VOLTAGE
    This is the maximum recommended peak DC operat-
    ing voltage for continuous duty at or below 85°C without
    DC voltage surges or AC ripple superimposed. No voltage
    derating is required below 85°C. Capacitors may be oper-
    ated to 125°C with working voltage linearly derated to 2/3
    of the 85°C rating at 125°C as shown in Figure 6.
    10. SURGE VOLTAGE
    Surge voltage is defined as the maximum voltage to
    which the capacitor should be subjected under transient
    conditions, including peak AC ripple and all DC transients.
    TABLE 1
    Surge Voltage Ratings
    A typical surge voltage test is performed at +85°C
    with the applicable surge voltage per Table 1. The surge
    voltage is applied for 1000 cycles of 30 seconds on volt-
    age through a 33 ohm series resistor and 30 seconds off
    voltage with the capacitor discharged through a 33 ohm
    resistor. Upon completing the test, the capacitors are
    allowed to stabilize at room temperature. Capacitance, DF,
    and DCL are then tested:
    1.
    The DCL should not exceed the initial 25°C limit.
    2.
    The capacitance should be within ±10% of initial
    value.
    3.
    The DF should not exceed the initial 25°C limit.
    11. REVERSE VOLTAGE
    Although these are polar capacitors, some degree of
    transient voltage reversal is permissible, as seen below.
    The capacitors should not be operated continuously in
    reverse mode, even within these limits.

    Reverse Voltage Ratings
    12. EQUIVALENT SERIES RESISTANCE (ESR)
    Equivalent Series Resistance (ESR) is the preferred
    high-frequency statement of the resistance unavoidably
    appearing in these capacitors. ESR is not a pure resis-
    tance, and it decreases with increasing frequency. Typical
    ESR limits are established in each specific product series.
    However, the ESR limits provided are for reference only,
    and are not necessarily the actual value that a particular
    Series product will attain.
    Total impedance of the capacitor is the vector sum of
    capacitive reactance (X
    ) and ESR, below resonance;
    above resonance total impedance is the vector sum of
    inductive reactance (X
    L
    ) and ESR.
    To understand the many elements of a capacitor, see
    Figure 8.
    A capacitor is a complex impedance consisting of
    many series and parallel elements, each adding to the
    complexity of the measurement system.

    tance. In most instances (especially in solid tantalum and
