Sales of Suntan Trimming potentiometers keep increasing these years, they rank as the second big series besides capacitors in Suntan, various resistances besides standard ones are requested, by using different resistance element, we get different resistance range in order to meet customer's requirement. 

Trimming Potentiometers have a resistive element made of carbon or cermet (a combination of CERamic and METal), or of resistance wire wound on an insulated copper mandrel.

The main advantages of wirewound trimmers are their low temperature coefficient, higher power dissipation, lower noise, tighter resistance tolerance, and, when used as a variable resistor, the excellent current-carrying capacity through the wiper due to the lower contact resistance. Also, their long-term resistance stability with time and temperature is slightly better than cermet. 

Cermet trimmers provide a wider resistance range (10 ohms to 5 megohms, versus a maximum of 100K ohms for wirewound). Also, the wiper output can be set closer to the desired value since the resistive element presents a continuous contact  surface for the wiper, as opposed to the discrete turns (resolution) of the wirewound. Other advantages with cermet are the lower reactance in high-frequency applications, the smaller sizes available, and the generally lower price than wirewound types.

More cermet series are provided to meet the blooming demand of lower price in the market, here is Suntan Trimming potentiometers family, then which resistive element do you prefer to? Are higher resistance needed? Or lower meet your request too? Welcome send comments and inquiries.
