ELQ3H7(TA)

ELQ3H7(TA) is the tape-and-reel ordering form of the Everlight ELQ3H7 quad transistor-output optocoupler in SSOP-16, verified against the maker’s official coupler selection guide and the family ordering composition: this type carries no current-transfer-ratio rank (the guide’s rank field for it is blank), and its single transfer specification is a current transfer ratio of 50 % to 600 % at 5 mA input current. Two further figures are the guide’s own: an isolation voltage of 3750 Vrms and a collector-emitter breakdown of 80 V. The selection point is four isolated channels in one low-profile 16-pin body for multi-loop feedback and PLC, industrial and appliance interfaces. The boundary of this page, stated plainly: the family sheet’s input-side electrical rows (forward voltage, saturation voltage, dark current) were not captured word-for-word for this code during verification, so they are not claimed here rather than read across from the EL3H7 sibling sheets — the transfer band and the two figures above are the verified substance. Selection advice: check an offer against the 50 % to 600 % band and the full (TA) string; a ranked coupler is a different component for loop-design purposes. Parameters verified against the Everlight ELQ3H7 selection-guide data.
