Creativity knows no bounds and this seems to be true in the case of Sparebots. Sparebots are more commonly referred to as Life of Sparebots.

Sparebots are actually spare bits and as the name suggests are actually bits of spare electronic parts. These spare parts may be bits of wire, solder, resistors, leads, diodes and capacitors; used creatively to depict beautiful Sparebots.



There are a number of photographs on the life of Sparebots. These photographs highlight the creativity with which Sparebots are made. These Sparebots depict common life activities in new light. The sparebots are fast becoming a rage on the internet as many people find them interesting and funny.

We are always amazed when we see the complete list of components (http://www.capacitors.hk/products.html) and parts that are in some of today’s smartphones. Besides being the ‘latest and the greatest’ as far as technology goes, the parts are also getting smaller with every iteration and release.

 
Take, for example, the Apple iPhone 4S. Looking beyond the plastic enclosures, the LCD screens and the cameras, there are hundreds of surface mount board level components needed to build just one iPhone 4S including many types of capacitors, surely small size chip types preferrable, series including ceramic capacitor, tantalum capacitor, electrolytic capacitor... and different chip diode, LEDS and magnetic components. Some are needed for RF purposes, some for switching, and others for power management. Even more components are needed for memory and app processing.

In all, this list is not much different from the requirements of past iPhones or other smartphones, however, the size of the components and the vast array of components required will never cease to amaze us, in this way, Suntan always try to do better .

Suntan technical department are ready here to provide further supports capacitors and sales are ready to answer new inquiry.

On capacitors that are large enough (e.g. electrolytic capacitors) the capacity and working voltage are printed on the body without encoding. Sometimes the markings also include the maximum working temperature, manufacturer's name and other information.

Smaller capacitors use a shorthand notation, to display all the relevant information in the limited space. The most commonly used format is: XYZ J/K/M VOLTS V, where XYZ represents the capacitance (calculated as XY×10Z pF), the letters J, K or M indicate the tolerance (±5%, ±10% and ±20% respectively) and VOLTS V represents the working voltage.

Polarised capacitors, for which one electrode must always be positive relative to the other, have clear polarity markings, usually a stripe or a "-" sign on the side of the negative electrode. Also, the negative lead is usually shorter.

This is an effective resistance that is used to describe the resistive parts of the impedance of certain electronic components. The theoretical treatment of devices such as capacitors and inductors tends to assume they are ideal or "perfect" devices, contributing only capacitance or inductance to the circuit. However, all (non-superconducting) physical devices are constructed of materials with nonzero electrical resistance, which means that all real-world components contain some resistance in addition to their other properties. A low ESR capacitor typically has an ESR of 0.01 Ω. Low values are preferred for high-current, pulse applications. Low ESR capacitors have the capability to deliver huge currents into short circuits, which can be dangerous.

For capacitors, ESR takes into account the internal lead and plate resistances and other factors. An easy way to deal with these inherent resistances in circuit analysis is to express each real capacitor as a combination of an ideal component and a small resistor in series, the resistor having a value equal to the resistance of the physical device.

When used in a direct-current or DC circuit, a capacitor blocks the flow of current through it, but when it is connected to an alternating-current or AC circuit, the current appears to pass straight through it with little or no resistance. If a DC voltage is applied to the capacitors conductive plates, a current flows charging up the plates with electrons giving one plate a positive charge and the other plate an equal and opposite negative charge. This flow of electrons to the plates is known as the Charging Current and continues to flow until the voltage across both plates (and hence the capacitor) is equal to the applied voltage VC At this point the capacitor is said to be fully charged with electrons with the strength of this charging current at its maximum when the plates are fully discharged and slowly reduces in value to zero as the plates charge up to a potential difference equal to the applied supply voltage and this is show below.
