53. Relay Behavior and Failures

Question.6

Hardware Developer is selecting a PCB relay to switch an AC-powered 230V/8A heater element from a microcontroller running on 3.3 V logic. The MCU drives the coil through an NPN transistor with the 3.3 V rail available for the coil supply. The design requires:

SPDT general-purpose PCB relay, coil voltage 3.3 V (or 5 V), contact rating ≥ 10A @ 250VAC, through-hole mount

She chooses the DigiKey part number: Z2570-ND (Omron G5LE-1 DC12)

Is this the correct component for the given requirement?
