I have been using that mic without the capacitor. When I checked, there was one on the board in the mic.
You just need to make the connection with either a 3.5 mm TRS plug to 4 pin jack, or cut off the 4 pin plug and connect a 3.5 mm TRS plug. The tip is the mic, the ring is PTT and sleeve goes to the ground/common for both.
For my rigs, the mic gain is set between 4 and 5 on the dial. That seems to provide the correct amount of output without distortion.
Good luck and happy QSOs.
