Our main super capacitor, farad capacitor, gold capacitor. Deputy foreign brands have Korean korchip, Korea VINA. We do super capacitor has more than 8 years of history, and by the majority of customers in the industry and the production of super capacitor manufacturers of praise. We also have Japanese electrolytic capacitors ruby, RTC real time clock (with crystal Warming) chip, super capacitor in series circuit chip balance. Our aim is: a good guest service, create a better future. 3V farad capacitor: 3.3F, 5F, 10F, 15F, 25F, 50F, 100F, 350F, 400F, 500F how fast I can give super capacitor discharge? ◆ super capacitors can be charged and discharged quickly, subject only to the peak current limiting resistance, or short circuit is not fatal. ◆ actually depends on the size of the capacitor monomer, for the matched load, small monomers can put 10A, macromonomers can put 1000A. ◆ Another constraint is that the discharge rate of the heat, the rate of repeated intense discharge to the capacitor temperature will rise, resulting in disconnection. RTS14 is an embedded real-time clock module temperature compensated crystal 32.768KHz, fully compatible with EPSON RX-8025T, which integrates a real-time clock chip with 32.768KHz crystal with temperature compensation function is a high stability, high reliability, high performance, real-time clock chip, which uses a standard SOIC14 package, standard I2C communication interface, programmable frequency output that can provide high reliability, real-time clock function for the user, is to replace the current use of poor performance DS1302, PCF8563 ideal device and so on. At -40 ℃ - within the range of +85 ℃, can achieve the highest accuracy of ± 3.4PPM, the same day the maximum error does not exceed 0.3 seconds. Widely used in multi-rate meter, industrial instrumentation, automotive electronics, calendar, taxi meter, industrial timers, industrial timers, timers and other sports products.
