Suntan What is mylar capacitor?

A mylar capacitor uses mylar, which is a type of high temperature polyester film, as its dielectric. It is typically very stable and able to operate over a wide range of temperatures, usually up to 125 degrees Celsius. As such therefore this type is a common choice for instrumentation equipment, also high quality audio and communications equipment. There may be various shapes, sizes and styles of construction but possibly the longest lived and most recognisable style is the green or brown resin-dipped radial type, which coupled with a small physical size makes it readily suitable for circuit boards.

Potentiometers can be obtained with either linear or logarithmic laws (or "tapers").

Linear taper potentiometer

北斗棋牌官网app下载A linear taper potentiometer (Below Figure)has a resistive element of constant cross-section, resulting in a device where the resistance between the contact (wiper) and one end terminal is proportional to the distance between them. Linear taper describes the electrical characteristic of the device, not the geometry of the resistive element. Linear taper potentiometers are used when an approximately proportional relation is desired between shaft rotation and the division ratio of the potentiometer; for example, controls used for adjusting the centering of (an analog) cathode-ray oscilloscope.

Logarithmic potentiometer

A logarithmic taper potentiometer (Below Figure)has a resistive element that either 'tapers' in from one end to the other, or is made from a material whose resistively varies from one end to the other. This results in a device where output voltage is a logarithmic (or inverse logarithmic depending on type) function of the mechanical angle of the pot.

北斗棋牌官网app下载Logarithmic taper potentiometers are often used in connection with audio amplifiers. The most common use of a pot in audio is as a volume control. Since our hearing has a logarithmic response to sound pressure, it is important that the volume control should provide a smooth variation from soft to loud, such that a given change in position of the pot causes the same sensation of volume change at all levels.

In the early days, when an audio taper (logarithmic, or just log) was needed, the resistance element was indeed tapered, so that it provided a different resistively at different settings. By changing the physical taper, it was possible to make a pot provide the exact gradient of resistance needed. By definition, a linear pot has no taper as such (the resistance element is parallel sided), but the term has stuck, so we might as well get used to it.

北斗棋牌官网app下载The violet curve in Figure shows an antilog or reverse audio taper pot. These are quite uncommon, but used to be used for balance controls using a log/antilog dual section (commonly called dual gang) pot. It is shown on the graph mainly for its interest value, but they are generally an historical component now.

Suntan Show you about Trim pots in many different shapes and sizes

北斗棋牌官网app下载 also come in many different shapes and sizes, with wattage ranging from 0.1W to 0.5W. Below shows several different trim pots, along with the symbol.

北斗棋牌官网app下载Resistance adjustments are made via a screwdriver. Exception is the trim pot on the lower right, which can be adjusted via a plastic shaft. Particularly fine adjusting can be achieved with the trim pot in the plastic rectangular casing (lower middle). Its slider is moved via a screw, so that several full turns is required to move the slider from one end to the other.

Suntan Tell You Potentiometer Have Many Different Shapes and Sizes

Suntan Technology Company Limited
----All Kinds of Capacitors

 come in many different shapes and sizes, with wattage ranging from 1/4W (coated pots for volume control in amps, etc) to tens of watts (for regulating high currents). Several different pots are shown in the photo below, along with the symbol for a potentiometer.

The upper model represents a stereo potentiometer. These are actually two pots in one casing, with sliders mounted on shared axis, so they move simultaneously. These are used in stereophonic amps for simultaneous regulation of both left and right channels, etc.

Lower left is the so called slider potentiometer.

Lower right is a wire-wound pot with a wattage of 20W, commonly used as rheostat (for regulating current while charging a battery etc).

For circuits that demand very accurate voltage and current values, trimmer potentiometers (or just trim pots) are used. These are small potentiometers with a slider that is adjusted via a screwdriver.

Suntan With Coated Potentiometers and Wire-Wound Potentiometers

北斗棋牌官网app下载Previous blog we talk about Potentiometers by means of construction, they can be divided into 2 groups: coated and wire-wound. Now let us to to know more related details of it.

北斗棋牌官网app下载With coated potentiometers, (as shown follow figure), insulator body is coated with a resistive material. There is a conductive slider moving across the resistive layer, increasing the resistance between slider and one end of pot, while decreasing the resistance between slider and the other end of pot.

Wire-wound potentiometers are made of conductor wire coiled around insulator body.  There is a slider moving across the wire, increasing the resistance between slider and one end of pot, while decreasing the resistance between slider and the other end of pot. Wire-wound potentiometers are used in devices which require more accuracy in control. They feature higher dissipation than coated pots, and are therefore in high current circuits. Construction of a wire-wound circular potentiometer (as shown follow figure). The resistive element (1) of the shown device is trapezoidal, giving a non-linear relationship between resistance and turn angle. The wiper (3) rotates with the axis (4), providing the changeable resistance between the wiper contact (6) and the fixed contacts (5) and (9). The vertical position of the axis is fixed in the body (2) with the ring (7) (below) and the bolt (8) (above).

Coated pots are much more common. With these, resistance can be linear, logarithmic, inverse-logarithmic or other, depending upon the angle or position of the slider. Most common are linear and logarithmic potentiometers, and the most common applications are radio-receivers, audio amplifiers, and similar devices where pots are used for adjusting the volume, tone, balance, etc..

Potentiometer by means of construction can be divided into 2 groups

Potentiometer (or pot, as it is more commonly known) is a simple electro-mechanical transducer used as a voltage divider. It converts rotary or linear motion from the operator into a change of resistance, and this change is (or can be) used to control anything from the volume of a hi-fi system to the direction of a huge container ship as voltage or current regulators in electronic circuits. By means of construction, they can be divided into 2 groups: coated and wire-wound.
