BOM rule hits · not reviewed — A hit means a BOM line matched this category's rules (ruleset 1.0.1+12960cbec977). It is a lead to read, not a located or reviewed circuit; several lines in one category are not several circuits.
Selection parameter template (suggestion)
What one usually states when choosing a circuit of this kind — not the parameters of any design or module listed here, and never a filter.
| Parameter | Suggested range or common values | Where it comes from |
|---|---|---|
| Isolation voltage (Vrms)Decisive | 2,500 to 5,000 Vrms | Redefined here |
| Current transfer ratio (CTR) (%)Decisive | 20 to 600 % | This category's own |
| Output typeDecisive | PhototransistorLogic-gate outputDarlingtonThyristor (SCR/triac) | This category's own |
| Rate (Mbps)Important | 0.01 to 50 Mbps | Redefined here |
In the parent's template, not in this one: Channels, Common-mode transient immunity (CMTI), Supply voltage
