the choice of plate-捕鱼软件下载

plate-shaped high-power ceramic capacitors are widely used in the field of equipment. however, many businesses do not really understand this type of capacitor, but let the price determine their choice. this is extremely unscientific, you must know that when purchasing materials, easy to use is the last word.
i often come across such a customer: i want a 1000pf high-power capacitor. ask him the size, ask him the detailed parameters, then ask three questions. on the contrary, he only pays attention to the price. this is the most headache. because according to him the capacity requirements can be made into many sizes. according to the big quotation, it is likely to be dropped by p, because it is too expensive. according to the small quotation, it is very likely that the quality of the complaint is not good. it can be said that it is not good.
when communicating with customers, it is necessary to clearly tell the customer the capacitance of different sizes, how big is the difference. take the 1000pf mentioned above as an example:
first, the power is different. 1000 pf with a diameter of 80 mm, the power is 15 kva; and the capacitance of 110 mm with a diameter of 40 kva; when the diameter is 140 mm, the power reaches 100 kva. the largest size is 200 mm diameter, and the power reaches 300 kva; to ask: how much power does your device require?
second, the current is different. 1000pf high-voltage plate-shaped high-power capacitor, diameter 80mm, current is only 20a; diameter 110mm current is also 20a; diameter 140mm, current has 30a; and the largest diameter in the species 200mm, current reaches 60a ask if the customer's current is within range.
third, the voltage level is different. the diameter of 80mm products, the voltage is 8kv; the diameter of 110mm capacitors, the rated voltage is 12kv, the diameter of 140mm capacitors, the voltage is 20kv, and the largest one is 200m diameter, the voltage is 30kv. obviously, the voltage level the difference is very big. once you use the wrong, it is easy to blow up!
the following is a comparison of the above parameters:

in addition to the above, the latter three diameter products can also be made into products with claws. it’s better than not knowing, one is scared, right? so when we communicate with customers, in addition to capacity, we also ask to voltage, current, power. if these are not clear, then at least he can tell us how big the product they are using now. ask more questions and reduce unnecessary problems.
