For about unstressed э, i.e. [ɛ] after a hard consonant, after a vowel or at the beginning of a word, it is rather rare and can be found only in loanwords:
экран, эфир, коэффициент, муэдзин, диэлектрик.
It is normally reduced from [ɛ] to [ɨ] or [ɘ], but not to [ɪ]:
[ɨkˈran]
[ɨˈfʲir]
[kəɨfʲɪʦɨˈɛnt]
[mʊɨˈdzʲin]

Exception: иэ as in [dʲɪ.ɪˈlʲektrʲɪk], ɪ + ɨ is assimilated to ɪ + ɪ.
