The supply span ranges from 10 V to 40 V. Note the RoHS non-compliant marking — the TO-99 metal can uses lead-based solder in the hermetic seal, which is exempt from RoHS for high-reliability applications. If your BOM requires RoHS compliance, this part does not meet it.","metaTitle":"OP43FJ J-FET Op-Amp, 1 Circuit, TO-99-8, -55°C to 125°C","metaDescription":"OP43FJ J-FET op-amp, single circuit, 10 V to 40 V supply, TO-99-8 metal can, -55°C to 125°C.
