Catalog excerpts

High sensitivity, for flame detection The T15770 is a high-sensitivity thermopile detector suitable for ﬂame detection. Infrared energy generated from ﬂame has spectral characteristics of peak wavelength 4.45 μm. The light input window of the T15770 employs the band-pass ﬁlter which passes the light of this wavelength. Flame detection TO-18 package High sensitivity Absolute maximum ratings Parameter Symbol Speciﬁcation Operating temperature Topr -30 to +85 Storage temperature Tstg -40 to +125 Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the within the absolute maximum ratings.
