Name: polypropylene capacitors Symbol: CBB The electric capacity: 1000 p - 10 u Rated voltage: 63-2000 - v Main features: performance similar to eps but small size, slightly poor stability Application: replace most of eps or mica capacitor, used in circuit of high demand Name: mica capacitor Symbol: CY The electric capacity: 10 p - 0. 1 u Rated voltage: 100 v - 7 kv Main features: high stability, high reliability, small temperature coefficient Application: high frequency oscillation and pulse to demand higher circuit Name: high-frequency ceramic dielectric capacitors Symbol: CC Capacity: 1-6800 p Rated voltage: 63-500 - v Main features: small loss at high frequency, stability is good Application: high frequency circuit Name: low-frequency ceramic dielectric capacitors Symbol: CT The electric capacity: 10 p - 4. 7 u Rated voltage: 50 v, 100 v Main features: small volume, low price, loss is big, poor stability Application: for high frequency circuit Name: glass glaze capacitor Symbol: CI The electric capacity: 10 p - 0. 1 u Rated voltage: 63-400 - v Main features: has good stability, low loss, high temperature (200 degrees) Applications: pulse, coupling, bypass circuit, etc Name: aluminum electrolytic capacitor Symbol: CD Capacitance: 0. 47-10000 u Rated voltage: 6. 3-450 - v Main features: small size, large capacity, loss is big, big leakage Application: the power supply filter, low-frequency coupling, decoupling, bypass, etc Name: tantalum electrolytic capacitor (CA), columbium electrolytic capacitor (CN) Symbol: Capacitance: 0. 1-1000 u Rated voltage: 6. 3-125 - v Main features: loss, leakage is less than aluminum electrolytic capacitor Application: in demanding instead of aluminum electrolytic capacitor in the circuit Name: air dielectric variable capacitor "> capacitor Symbol: The substation capacity: 100-1500 p Main features: low dissipation, high efficiency; Can made according to the linear, linear wavelength, linear frequency and logarithmic type, etc Application: electronics, radio and television equipment, etc Name: film dielectric variable capacitor "> capacitor Symbol: Substation capacity: 15-550 p Main features: small volume, light weight; Loss is bigger than air medium Application: communication, radio receiver, etc Name: film dielectric padder "> capacitor Symbol: The substation capacity: 1-29 p Main features: loss is bigger, small volume Application: radio, electronic instruments, such as circuit circuit compensation Name: ceramic dielectric padder "> capacitor Symbol: Substation capacity: 0. 3-22 p Main features: loss smaller and smaller Application: accurate tuning of high-frequency oscillation circuit Monolithic capacitor temperature coefficient is very high, is the chief drawback of oscillator steady drift to bear, we did a 555 oscillator, capacitance is just next to the 7805, after startup, use an oscilloscope to see frequency, watched it changes slowly, later by polyester capacitor is better. The characteristics of monolithic capacitors: Large capacity, small volume, high reliability, stable capacitance, resistance to high temperature and wet resistance good, etc. Scope of application: Widely used in electronic precision instruments. All sorts of small electronic equipment for resonance, coupling, filtering, by-pass. Capacity range: 0.5 PF - 1 uf Pressure: two times the rated voltage. Inside said monolithic also called multilayer ceramic capacitors, divided into two types, type 1 Performance is quite good, but the capacity is small, generally less than 0. 2 u, another call Type II, large capacity, but the performance in general. In terms of WenPiao: Monolithic about is wen si number + 130, CBB - 230 with negative temperature coefficient, with appropriate proportion used in parallel, can make the WenPiao to small. As for the price: Tantalum, niobium capacitor is the most expensive, monolithic, CBB cheaper, ceramics, ceramics is a bit expensive. But there is a high frequency zero WenPiao black spots mica capacitor high Q value, also is a bit expensive.
