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.

Suntan Silver Mica Capacitors with high reliability (SM tradmark)

Suntan Silver Mica Capacitors are available with values that range from 1–22,000 pF, voltages are in the range 50–1000V for standard dipped mica capacitors. Mica capacitors exhibit very little voltage dependence, have high Q or conversely small power factors that are quite independent of frequency. With all these advantage, our mica capacitors are ideal for high requence and RF applications.

Silver Mica Capacitors Knowledge

Silver mica capacitors are high precision high stability high reliability capacitors. They are available in small values, and are mostly used at high frequencies.

Mica capacitors, which are now obsolete, were in use in the early 20th century. They consisted of sheets of mica and copper foil sandwiched together and clamped.

Silver mica capacitors, also known as silvered mica capacitors, obsoleted mica capacitors. Instead of being clamped with foils these use sheets of mica coated on both sides with deposited metal. The assembly is dipped in epoxy. The advantages are:

• greater stability, since there are no capacitive airgaps that can change dimension,
• airtight enclosure removes the risk of oxidation or corrosion of plates or connections.
• greater value per volume, since
• there are no airgaps between plates and mica,
• the conducting surfaces can be thinner.
• no clamping mechanism is needed

To read a potentiometer, you need a multimeter. Put in on the proper ohmmeter setting, which should be higher than that of the resistance rating of the potentiometer as noted on the package or the device. If you don't know the resistance rating, use the lowest setting of the multimeter and increase it until you get a reading.
When reading the potentiometer, one multimeter lead must always be on the wiper or middle part, and the other one can be on either of the remaining terminals. For example, place one multimeter lead on the wiper, and the other on the left terminal of the potentiometer. If you place one lead on the left terminal and the other on the right, you will read the entire value of the pot, and the resistance will not vary when you turn the knob.
Note that Inexpensive ones may approximate only fifty percent of their rated value when they are measured.
we can offer all kinds of trimming potentiometers accept very small quantity with very competetive price, the delivery time is 2 weeks around. With our good support, our sales is keep increasing each month.Any questions ,please contact us at once.

Trimming Potentiometers come in different types.
Rotary and trimming potentiometers are wire wound, and are single or multi-turn, depending on the number of times the knob may be turned. The resistance is lowered or increased by turning the knob clock or counterclockwise, where the knob direction is dependent on the end that is used with the wiper.Faders or sliders as they are also known, have a rectangular shape, and the wiper moves back and forth in a linear fashion.
 
Potentiometers work by having a resistive element inside. Both end terminals are attached to it, and do not move. The wiper travels along the strip when the knob is turned. The closer the wiper is to the end terminal it is wired in conjunction with, the less the resistance, because the path of the current will be shorter. The further away it moves from the terminal, the greater the resistance will be.

The symbol for a potentiometer is the same one as a resistor, save for an arrow in the middle. In a circuit where they are used strictly as variable resistors or rheostats, only two terminals are wired to the other components. All three terminals are wired separately when they function as voltage dividers. Light dimmers in houses and volume controls on electronics are two common applications. Others include switches and position sensors.
