Reference Specification DEF Series/6.3kVp-p Lead Type Disc Ceramic Capacitors for LCD Backlight Inverter Circuit only 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 The frequency of the applied sine wave voltage should be less than 100kHz. The applied voltage should be less than the value shown in following figure. In case of non-sine wave which include a harmonic frequency, please contact our sales representatives or product engineers. 10000 The temperature of the surface of capacitor: 10pF below the upper limit of its rated operating temperature range (including self-heating.) 6300 12 ~ 22pF 27 ~ 47pF The capacitors can be applied maximum 6.3kVp-p at 100kHz when lamps turn on. Voltage AC Voltage 1000 1 10 100 Frequency kHz Positional 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 similar current, it may self-generate heat due to dielectric loss. Excessive heat may lead to deterioration of the capacitor s characteristics and reliability. (Never attempt to perform measurement with the cooling fan running. Otherwise, accurate measurement cannot be ensured.) 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 chip : 400 max. Soldering iron wattage : 50 W max. Soldering time : 3.5 s max.
