Neither a Raven nor a Raven Fleet Issue can decently active tank. You need a golem for that 
In the screenshot, your raven has 305s shield booster cycling before the capacitor is depleted. If that’s a Multispectrum Shield Hardener II
in the screenshot, the Raven will generate 44ehp/s passively and another 232ehp/s using the shield booster, for 305s. After that time is over, you have to warp out, or to have finshed the NPCs. In 305s, you generated 305s * (44ehp/s + 232ehp/s) = 84k ehp
. The Raven also has 37k ehp buffer, yielding 120k ehp.
If you fit shield exenders and hardeners instead, a Raven can easily surpass the ability to tank 120k ehp for 5 minutes, especially as the passive shield regeneration increases as the buffer does. To a Passive Tanked fit, capacitor is less of a problem, too, allowing the fitting to be focused on damage application and amplification rather then capacitor pressure.
Currently, the Fit completely lacks damage application modules. If your strategy revolves around Microjump Driving and then sniping the NPCs while manouvering around, you might want to install a Target Painter
on the Raven. If you prefer fighting in the intermediate or even close distance range, you should put a Stasis Grappler
or a Stasis Webifier
or even better, both, on the Raven.
The Low Slot Capacitor Generators can be swapped with Missile Guidance Enhancers
for marginally better application, a Damage Control
and a Power Diagnostic
for Tank, or Nanofiber Internal Structure
for manouverability… well if you want to manouver it though, most raven just sit around or move in a straight line.
Rigs, too, can be selected from the Missile Launcher Rigs
category to improve your damage output quality, or from the Shield Rigs
category to improve your tank.
For the Microwarp Drivers, the Quad Lif Restrained
variant has less negative capacitor modifier then the other Meta Microwarps, which is important when capacitor is a problem, and it also has less signature modifier, which is always good.

Large Core Defense Field Extender I
Large Core Defense Field Extender I
has the same launchers and therefore same damage as the active tanked Raven, but is capacitor stable and has 169k ehp buffer and 200ehp/s passive shield regeneration. The Launchers should become T2 if possible, as Fury Missiles are less expensive then Faction ones, and the target painter compensates for the fury’s poorer application, while the higher raw damage means more damage on Battlecruiser and Battleship types. Upgrading the Target Painter to a T2 one increases the application.
Also, a Raven will naturally have a harder time with EM spamming foes like Blood or Sansha. It can be fit with specific tank modules to mitigate the EM weakness, but you can also be picky and prefer running missions that ask you to wreck Angel or Gurista or Serpentis instead.
