The selection of

24、core sizes for this standard is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry. See IEC 62317-1 for more detail concerning the philosophy of selecting core sizes to be included. The genera

Before optimizing for performance, the following ho

46、le diameter ranges were chosen: 0,95 mm to 1,05 mm for P5,8/3,3 1,05 mm to 1,15 mm for P7,4/4,0 2,0 mm to 2,2 mm for P9/5, P11/7 3,0 mm to 3,2 mm for P14/8, P18/11 4,4 mm to 4,7 mm for P22/13 5,4 mm to 5,7 mm for P26/16, P30/19, P36/22 Originally a pot-core 14 mm 8 mm, with an adjusting device of 3

47、mm diameter was the smallest that could be produced in quantity. Due to miniaturization of electronic devices, four smaller pot-cores, P7,4/4,0, P5,8/3,3, P4,6/3,1 and P3,3/2,6 were added as standard pot-cores, and the larger pot-core P42/29 was deleted. The ratio of diameter to height of the pot-co

48、re, calculated on the above assumption, is fairly constant, as appears from the list below, where A/2B lies between 1,48 and 1,76, except for the smallest type.
