Description

      The 685PPB250K is one kind of polypropylene film capacitors for power semiconductor circuits. The 685PPB250K is a multifunctional product which has many additional features that you should make it clear before you purchase this kind of product. The first feature you must know is that the 685PPB250K is a snubber capacitor which is for energy conversion. The second one you should pay attention to is that the product has high pulse current applications which can attract a lot of consumers. Because of the feature, the product can have a high competitive power compared with other this kind product. What's more, the paoduct has a high voltage and a high current. The last but not the least important is that the 685PPB250K has a SCR communication and TV deflection ckts. Only by knowing the information above can you make a good and correct choice.
      The 685PPB250K has some specifications you should make an understanding. The first one you should make an understanding is about the capacitance tolerance which is +/- 10% at 1kHz, 20°C. As is known to all, the temperature is an important factor during operating. So making an understanding of the temperature is essential, and the operating temperature ranges from -55°C to +105°C. The third one you also should know is about the rated voltage of 685PPB250K which is for T>85°C voltage must be rated by 1.25% for every °C above 85°C. The forth one you should pay attention to is about the dielectric strength. When the temperature is 20°C between leads, the dielectric strength is 160% of rated VDC for 2 seconds. The fifth one you should make an understanding is about the load life which is 2000 hours at 85°C±2°C with 125% of rated voltage. What's more, you should know that the self inductance which is less than 1nH/mm of capacitor lead spacing. The seventh one is about the capacitance drift which is less than 0.5% up to 40°C after 2 years. The last one is about the coating of 685PPB250K which is solvent resistant plastic box (UL94V-1) with epoxy end seals (UL 94V-0).
