The recommended PCB layout for the TQ2SA-3V relay is to have a minimum of 1.5 mm clearance around the relay and to use a ground plane under the relay to reduce electromagnetic interference (EMI).
To ensure reliable switching of the TQ2SA-3V relay, make sure to follow the recommended drive circuit and voltage levels, and ensure that the relay is properly soldered and seated on the PCB.
The maximum switching frequency of the TQ2SA-3V relay is 30 Hz, but it's recommended to limit the switching frequency to 10 Hz or less to ensure reliable operation and extend the relay's lifespan.
The TQ2SA-3V relay is rated for operation up to 85°C, but it's recommended to derate the relay's current handling and switching frequency at higher temperatures to ensure reliable operation.
To minimize EMI, use a shielded cable for the relay's coil connections, and consider adding a ferrite bead or common-mode choke to the coil circuit to reduce EMI radiation.
