I can not decipher such a sign FFD 450 TDK BS This inscription is on the casing of this something that has three legs. Maybe someone knows what transistor and optional substitutes are. :|

Hello And what does it work in and what does it do more ???? Regards, Sonia Added after 6 [minutes]: see it: ewentulanie patches in the search engine d450 password because it seems to me that it will be some IRF but you have to specify where it works and what this element does

Is it really about tranzysor? This designation may also apply to the 450kHz ceramic filter. andy_o

Everything indicates that it is IRF, it's stupid to me that I did not fall into it anymore. Thank you very much for your help
