CBB capacitor characteristics

CBB capacitors have been shuttled in our lives. Commonly used in household appliances, CBB capacitors are not unfamiliar to everyone. What are the characteristics of CBB capacitors?

CBB capacitor is non-inductive, made of polyester film as medium and aluminum foil for electrode winding, tinned copper clad steel wire with epoxy resin encapsulation; 1, CBB capacitor stability and reliability; 2, no induction The structure reduces the loss factor to a low level; 3. Excellent environmental performance. 4. ESR is low. Technical requirements: rated temperature: -40 ° C ~ ~ +85 ° C; rated voltage: 100V, 250V, 400V, 630V; capacitance range: 0.001UF ~ ~ 0.47UF; capacitance deviation: plus or minus five (J) ±10 (K), plus or minus twenty percent (M); loss tangent angle: one percent (max) at 1 kHz; withstand voltage: Teminal to (at 20 ± 5 ° C). CBB capacitors are ideal for commercial equipment where small signal circuits are required to reduce noise.

Metal film capacitors feature high resistance, good solderability and self-resetting properties, and miniature space saving. Specifications: 1, working temperature: -40 ° C ~ ~ +85 ° C; 2, capacitance range: 0.01 UF ~ ~ 10UF; 3, capacitance tolerance: plus or minus five percent (J), ± 10 (K), positive and negative Twenty percent (M); rated voltage: 100V, 250V, 400V, 630V; loss tangent angle: one percent (max) at 1KHz; withstand voltage: Teminal to (at20 ± 5 °C). This product is suitable for In coupling, filtering, rectification and timing circuits, it is widely used in equipment for remote communication, data processing, industrial instrumentation and automatic control systems.

Film capacitors are excellent capacitors because of their excellent characteristics. Its main characteristics are as follows: no polarity, high insulation resistance, excellent frequency characteristics (wide frequency response), and low dielectric loss. Based on the above advantages, the film capacitor is used in a large amount on the analog circuit. In particular, in the part where the signal is connected, it is necessary to use a capacitor having a good frequency characteristic and a very low dielectric loss to ensure that the signal is transmitted without excessive distortion. Among all the plastic film capacitors, the characteristics of polypropylene (PP) capacitors and polystyrene (PS) capacitors are remarkable. Of course, the prices of these two capacitors are also relatively high.
