2MA Series
Dual Winding Shielded Inductor/Transformer
Accetek A
FEATURES
Dual winding shielded inductor can be used as single/dual/coupled inductor or 1:1 transformer
Operating Temperature range from -40°C to +125°C (Including Self-heating)
260°C reflow peak temperature qualified
Inductance up to 1mH in parallel mode for all case size
High strength sealing epoxy with stable temperatures character to keep the parts strong at wide range temperatures:
(Typical Hardness: ShoreD 86 @25°C, ShoreD 70 @125°C)
 Available for 4 case size, up to 129 size (12.5×12.5×10.0mm) to meet with higher current requirements
 Recommend for SEPIC and Flyback applications
 Custom designs on request
