What does ".1M/250" mean as a capacitor rating?
That is a typical capacitance, type of capacitor, and voltage rating for the capacitor used in a dimmer. The voltage rating is a DC rating. The capacitor actually only sees the diac breakdown voltage (typically 30-40 volts) plus a volt or two for the triac gate. The "M" does not stand for microfarads- rather it is a tolerance code. J = +/-5% ...

Operating the part at lower values than rated specifications. How it is related to positive and negative temperature coefficient. Running a part at a lower voltage or current means less heat is generated. Powering a 16v max capacitor, at 16v, is stressing it.
Ripple Current and its Effects on the Performance of Capacitors
Capacitors are critical elements in most analog and digital electronic circuits. One of the limitation – the power dissipated by a capacitor is a function of ripple current and ESR equivalent series resistance.As such, the ripple current capability is one of the key parameters to consider when selecting a capacitor for a specific application.

What does the Voltage Rating on a Capacitor Mean?
It is normally recommended to give a good amount of room when choosing the voltage rating of a capacitor. Meaning, if you want a capacitor to hold 25 volts, don''t choose exactly a 25 volt-rated capacitor. Leave some room for a safety margin just in case the power supply voltage ever increased due to any reasons.
Understanding & Selecting Capacitors
A typical run capacitor rating ranges from 2 µF to 80 µF and is either rated at 370 Vac or 440 Vac. A properly sized run capacitor will increase the efficiency of the motor operation by providing the proper "phase angle" between voltage and current to create the rotational electrical field needed by the motor.

18.5 Capacitors and Dielectrics
Consider again the X-ray tube discussed in the previous sample problem. How can a uniform electric field be produced? A single positive charge produces an electric field that points away from it, as in Figure 18.17.This field is not uniform, because the space between the lines increases as you move away from the charge.
What Is the Difference Between uF and MFD Capacitors?
Older capacitors were commonly designated as MFD or mFD, either due to the difficulties of producing the symbol print on the shell or for other manufacturer-specific reasons.
