Polyester Capacitor refers to the use of two pieces of metal foil as electrodes, sandwiched in a very thin insulating medium, rolled into a cylindrical or flat cylindrical core, the medium is polyester, polyester film capacitor, high dielectric constant, volume Small, large capacity, good stability, suitable for bypass capacitors.
1, the capacitor withstand voltage value is usually expressed in letters, the common code and cardinality correspondence is:
A: 1.0; B: 1.25; C: 1.6; D: 2.0; E: 2.5; F: 3.15; G4.0;
H: 5.0; J: 6.3; K: 8.0; Z: 9.0;
2. The number in front of the letter indicates a power of 10, such as 2A, which is 102*1.0=100V, 2C is 102*1.6=160V, and so on.
3. The letter after the withstand voltage value indicates the capacitance capacity in pF.
For example, 823 indicates that the capacity is 82*10^3=82000Pf, and 224 indicates
4, 22 * 104 = 220000 pf = 0.22 μF; the last letter indicates the accuracy, such as J means the capacity tolerance is ± 5% and so on.
Typical example of capacitance identification: 2A823J is 82000Pf±5%, withstand voltage 100V
