I'm a bit confused by the model number you gave and the fact that your capacitor had Com, Fan and Herm terminals. Are you working on your furnace or the air conditioning unit? The capacitor terminals indicate an ac unit. Typically on a Carrier outdoor unit, the Yellow wire will be on the Com terminal, the Blue wire on the Herm terminal and the Brown wire on the Fan terminal on a compressor/condenser fan dual run capacitor. I would need the model number of the outdoor unit (ac unit) to confirm that 100% though. If you're working on your furnace, then you have the wrong capacitor for the blower motor. That capacitor should have only two terminal posts. Let me know either way and I'll clarify things. Thanks,Brian

ac unit.. but outside AC unit does not have model number
visible.
Expert:  Brian HVAC Guy replied 1 year ago.
Ah, ok thanks! The way for you to confirm my suggestion above is to follow the wires. The yellow should go to the compressor contactor, the blue to the compressor and the brown to the fan motor. I'm reasonably sure that's the case but without a model number I can't confirm it. You can by following the wires though. If there is more than one yellow wire, they both (all yellow) go on the com terminal. Let me know how it goes! Thanks,Brian
