A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification.

This is a widely used configuration, both with individual diodes wired as shown and with single component bridges where the diode bridge is wired internally.

For cermet trimming potentiometers, we offer competitive price, very speedy delivery ( mostly on stock), and very high quality. Do you want to try our price? Pls check our website: www.kingtromics.com and send inquiry. thanks.

The surge arrester is shown in Figure 7. It is built-up of 6 separate mechanical and electrical modules connected in series. The design of each module includes an HTV silicone rubber insulator moulded directly onto the internal structure with the  ZnO block column. The internal cage-style mechanical structure provides high mechanical strength and well controlled short-circuit capability in the event of arrester overloading.

The special location of the  arrester in the tower has required extensive 3D electrical field calculations to determine necessary grading rings to control the voltage distribution along the  arrester. The mass of the  arrester including the grading rings is 128 kg or approximately one third of the mass of an equivalent  arrester with porcelain housing. The creep age distance of 27 mm/kV corresponds to IEC class III.

Tantalum capacitors are under some conditions prone to self-destruction by thermal runaway. The capacitor typically consists of a sintered tantalum sponge acting as the anode, a manganese dioxide cathode, and a dielectric layer of tantalum pentoxide created on the tantalum sponge surface by anodizing. The tantalum oxide layer may have weak spots that undergo dielectric breakdown during a voltage spike. The tantalum then comes to direct contact with manganese dioxide and the leakage current causes a local heating; a chemical reaction then produces manganese(III) oxide and regenerates (self-heals) the tantalum oxide layer.

Kingtronics trimming potentiometers perform a variety of circuit adjustments in all types of electronic equipment. Trimmers are used in virtually every electronic market. Typical applications include measuring linear distance, angles or rotations in production equipment, industrial test and measurement equipment, and medical equipment.

The Schottky diode or Schottky Barrier diode is an electronics component that is widely used for radio frequency (RF) applications as a mixer or detector diode.

The Schottky diode is also used in power applications as a rectifier, again because of its low forward voltage drop leading to lower levels of power loss compared to ordinary PN junction diodes.

Although normally called the Schottky diode these days, named after Schottky, it is also sometimes referred to as the surface barrier diode, hot carrier diode or even hot electron diode.

1A Schottky Barrier Rectifier 1N5817-1N5819& 3.0A Schottky Barrier Rectifier 1N5820-1N5822 is Kt Mark which Kt Kingtronics produce and sell very well. In exhibition at FIEE in Brazil Kingtronics has success in showing Schottky Diode.

Kt Kingtronics offers leaded quartz crystal HC49U, HC49S and SMD quartz crystal HC49SMD. The quartz crystal market, in general, requires hands on customer service. Quartz crystals are manufactured for frequencies from a few tens of kilohertz to tens of megahertz. More than two billion (2×109) crystals are manufactured annually. We also stock crystals in most popular package styles, frequencies and specifications for quick delivery.

49USMD crystals are low profile surface mount crystals with the same footprint as standard HC49 and HC49-4H crystals. 49USMD crystals are ideal for use in low cost, mass-market applications but are also able to be produced to close tolerances when required. With a broad frequency range from 3.200MHz to 90.000 MHz, the HC49SMD can serve as a low cost solution in virtually any application or market. The HC49SD is available in surface mount (SMD) packaging only.

Tantalum capacitors offer several advantages over conventional multi-layer ceramic chip capacitors, such as larger capacitance in a more compact form factor and superior temperature and DC bias characteristics. Kingtronics broad lineup of tantalum capacitors include models that utilize a bottom electrode configuration, low ESR conductive polymer types, units with an open structure to prevent combustion and damage to peripheral components, and standard products featuring excellent mount ability and reliability.

ESR has been significantly reduced due to utilization of a conductive polymer instead of conventional manganese dioxide. In addition the conductive polymer type reduces the risk of smoke or ire compared with conventional products.

Gas-filled surge arresters operate on the gas-physical principle of the highly effective arc discharge. Electrically, surge arresters act as voltage-dependent switches. As soon as the voltage applied to the arrester exceeds the spark-over voltage, an arc is formed in the hermetically sealed discharge region within nanoseconds. The high surge current handling capability and the arc voltage, which is almost independend of the current, short-circuit the overvoltage. When the discharge has died down, the arrester extinguishes and the internal resistance immediately returns to values of several 100 MΩ.

The surge arrester thus meets almost perfectly all requirements made on a protective element. It reliably limits the overvoltage to permissible values, and – under normal operating conditions – the high insulation resistance and the low capacitance contribute to the fact that an arrester has virtually no impact on the system to be protected.
