Reference Specification DEB Series Lead Type Disc Ceramic Capacitors of Class 2 for General Purpose Product specifications in this catalog are as of Dec. 2017, and are subject to change or obsolescence without notice. Please consult the approval sheet before ordering.Please read rating and Cautions first. Reference only CAUTION 1. OPERATING VOLTAGE When DC-rated capacitors are to be used in AC or ripple current circuits, be sure to maintain the Vp-p value of the applied voltage or the Vo-p which contains DC bias within the rated voltage range. When the voltage is started to apply to the circuit or it is stopped applying, the irregular voltage may be generated for a transit period because of resonance or switching. Be sure to use a capacitor within rated voltage containing these irregular voltage. When DC-rated capacitors are to be used in input circuits from commercial power source (AC filter), be sure to use Safety Recognized Capacitors because various regulations on withstand voltage or impulse withstand established for each equipment should be taken into considerations. Voltage DC Voltage DC+AC Voltage AC Voltage Pulse Voltage(1) Pulse Voltage(2) Positional Vo-p Vp-p Vo-p Vp-p Vp-p Measurement 2. OPERATING TEMPERATURE AND SELF-GENERATED HEAT Keep the surface temperature of a capacitor below the upper limit of its rated operating temperature range. Be sure to take into account the heat generated by the capacitor itself. When the capacitor is used in a high-frequency current, pulse current or the like, it may have the self- generated heat due to dielectric-loss. The allowable frequency should be in less than 300kHz in sine wave. Applied voltage should be the load such as self-generated heat is within 20 C on the condition of atmosphere temperature 25 C. When measuring, use a thermocouple of small thermal capacity-K of 0.1mm and be in the condition where capacitor is not affected by radiant heat of other components and wind of surroundings. While, in case of non-sine wave which include a harmonic frequency, please contact our sales representatives or product engineers. 3. FAIL-SAFE When capacitor would be broken, failure may result in a short circuit. Be sure to provide an appropriate fail-safe function like a fuse on your product if failure would follow an electric shock, fire or fume. 4. VIBRATION AND IMPACT Do not expose a capacitor or its leads to excessive shock or vibration during use. 5. SOLDERING When soldering this product to a PCB/PWB, do not exceed the solder heat resistance specification of the capacitor. Subjecting this product to excessive heating could melt the internal junction solder and may result in thermal shocks that can crack the ceramic element. When soldering capacitor with a soldering iron, it should be performed in following conditions. Temperature of iron tip : 400 C max. Soldering iron wattage : 50W max. Soldering time : 3.5 s max.
