1) The combination surface of the iron core is flat and without skew.
2) BOBBIN, CORE and wiring pins should be kept clean and free from impurities and glue.
3) Identify where CORE with GAP is located.
4) The maximum skew of EE, EI and UU CORE shall not be greater than 0.5mm or 1/10core width.
General casing position rules:
A external: the distance between the end of the casing and the
PIN is as short as possible, but remember that the casing must
not be wrapped around the PIN, which will cause empty welding phenomenon.
B Interior: A infinity wall fit, flat paste BOBBIN about 1/2L length
B with the side wall, the casing must be in the stop wall.
The width and material...
