Switch-mode power supply transformer type EF
Operating frequency: 10 - 500 kHz
Switch-mode power supply applications with HAHN flyback converters are realized in the small and medium power range with sizes EF 12.6 - EF 30. The use of high-quality core materials enables operating frequencies up to the MHz range.
Extensive know-how and special processes for open, covered, impregnated or vacuum encapsulated transducers stand for HAHN quality and optimum customer benefit.
Ever shorter development times and ever higher production reliability - this is where the development of electronic assemblies is heading.
HAHN flyback converters have the following properties:
- Construction according to DIN EN 61 558
- Operating frequency 10 - 500 kHz
- Increased creepage distance 12 mm possible
Insulation material classes
- B/120 °C
- F/155°C
- 100 % lead-free
100 % routine test
- Inductivity
- Transformation ratio
- Winding sense
- Dielectric strength (50Hz/1s)
HAHN has the ability to optimally develop flyback converters as customized components for well-known switching regulator manufacturers such as Power Integration, Infinion, Philips or ON Semiconductor.
This stands for a fast, economical and high-quality solution from our company.
