That 350 V ceiling covers 240 VAC line switching with margin, while the 120 mA current handles signal-level loads like PLC inputs, sensor outputs, or small solenoid valves. The 35 Ohm on-state resistance (max) means the voltage drop across the relay at 120 mA is about 4.2 V — acceptable for many signal circuits but worth checking if the downstream load requires a tight voltage rail. ## 4-SOP surface-mount — board-fit checklist The 4-SOP is the same package used across the PhotoMOS AQY series, so a single PCB layout serves multiple current/voltage variants. Supplied in tube packaging — not tape-and-reel — so it is suited for prototype runs, low-volume production, or bench repair where a pick-and-place feeder is not needed.","metaTitle":"Panasonic AQY210KS PhotoMOS Relay, SPST-NO, 120 mA, 350 V","metaDescription":"Active Panasonic AQY210KS PhotoMOS relay, SPST-NO, 120 mA load, 350 V AC/DC, 35 Ohm on-resistance, 4-SOP surface mount.
