B45192R2157+40*
When using tantalum capacitors with manganese dioxide coating, following cautions warnings should taken into account: Polarity Because tantalum capacitors polar capacitors, important observe their polarity markings (positive pole anode, negative pole cathode). incorrect polarity resulting from voltage components must smaller than equal permitted polarity reversal voltage (see "General technical information", section section under avoid reducing their reliability, this voltage only occur short time, most five times duration minute hour. Voltage maximum continuous voltage depends ambient temperature. Within temperature range rated voltage equal maximum continuous voltage. Between maximum continuous voltage must reduced linearly from full rated voltage (derating). (only B4519*P series) voltage must reduced (only B4519*T series) rated voltage. Operation below maximum continuous voltage positive effect capacitor's failure rate. maximum continuous voltage must exceeded (see"Quality environment", section 1.11 under unfavourable operating conditions (such possible line overvoltages, unfavourable tolerances transformation ratio line transformer equipment, repeated overvoltages when equipment switched high ambient temperatures) must taken into account when determining operating voltage. surge voltage maximum voltage (peak value) that applied capacitor short periods, most five times total duration minute hour. surge voltage must applied periodic charging discharging course normal operation cannot part operating voltage. permissible surge voltage capacitors this data book rated voltage. occurrence voltage impulses (transient voltages) that exceed surge voltage lead irreparable damage. Capacitance actual capacitance capacitor deviate from rated capacitance much full magnitude tolerance delivery. capacitance varies with temperature +125 +12% +20%) decreases with increasing frequency (see "General technical information", section under

Low-resistance applications voltage networks low-resistance applications, EPCOS recommends maximum operating voltage half permissible maximum continuous voltage, that capacitors have sufficient tolerance withstand voltage peaks. Depending conditions use, early failure rate higher here factor than range with constant failure rate specified data book (see"Quality environment", section 1.11 under When operated directly voltage network, capacitor should protected against overvoltage, e.g. suppressor diode, against polarity reversal diode. capacitor operated unprotected low-impedance circuit fails because permissible conditions forward voltage, reverse voltage, surge current, power dissipation temperature exceeded, continued current flow through overstressed capacitor produce overheating. overheated capacitor damage surrounding components circuit board (see"Quality environment", section 1.11 "General technical information", section 4.11 under Storage conditions Capacitors with solid electrolyte stored temperatures down upper storage temperature must exceed (for blister tape temperature limit °C). storage conditions should exceed drypack useful prevent effects humidity.

following applies products named this publication: Some parts this publication contain statements about suitability products certain areas application. These statements based knowledge typical requirements that often placed products areas application concerned. nevertheless expressly point that such statements cannot regarded binding statements about suitability products particular customer application. rule, EPCOS either unfamiliar with individual customer applications less familiar with them than customers themselves. these reasons, always ultimately incumbent customer check decide whether EPCOS product with properties described product specification suitable particular customer application. also point that individual cases, malfunction passive electronic components failure before their usual service life cannot completely ruled current state art, even they operated specified. customer applications requiring very high level operational safety especially customer applications which malfunction failure passive electronic component could endanger human life health (e.g. accident prevention life-saving systems), must therefore ensured means suitable design customer application other action taken customer (e.g. installation protective circuitry redundancy) that injury damage sustained third parties event malfunction failure passive electronic component. warnings, cautions product-specific notes must observed. order satisfy certain technical requirements, some products described this publication contain substances subject restrictions certain jurisdictions (e.g. because they classed "hazardous").
