ICs

Monday, 28. February 2011 2:46

Integrated Circuits, also called ICs or informally, “microchips” or just “chips”, are miniature electronic circuits built onto a single (very small) piece of silicon embedded in a package that allows it to be connected to a cicuit. They can fulfill many functions, ranging from simple logic gates and other simple devices such as counters and shift registers, to computer processors.The earliest ICs used resistors and transistors, in a form called resistor-transistor logic (RTL). This was very prone to noise with more than three inputs, and as such was only suitable for very small-scale devices.Then is diode-transistor logic (DTL). This used diodes to supplement the resistors used in RTL, but still suffered many problems, including a very long propagation delay (the time taken to change state).Transistor-transistor logic (TTL) was a very popular format for ICs and is still in use in places today. This basically uses only transistors to fulfil its function.Most ICs today are CMOS which have a very low quiescent current usage, high noise immunity, and flexible voltage supply requirements.Other families include Emitter-coupled logic (ECL) and Integrated Injection logic (I2L).We are strong in many brands. Such as ST, TI, ATMEL, Fairchild, ADE, Maxium,  TOSHIBA, INFINEON, Philip, Sharp and so on.

Cement type resistors

Friday, 25. February 2011 2:47

A resistor is a two-terminal electronic component which implements electrical resistance as a circuit element.Resistors are used with transducers to make sensor subsystems. Transducers are electronic components which convert energy from one form into another, where one of the forms of energy is electrical. A light dependent resistor, or LDR, is an example of an input transducer. Changes in the brightness of the light shining onto the surface of the LDR result in changes in its resistance.As one kind of resistors,cement type resistors are made by winding resistance wires around non-alkaline ceramic core or metal oxide film rod, which is added with a layer of heat and humidity resistant and non-corrosive protective material.
FEATURES:
1.low noise
2.insulation fully can be used in p.c.b
3.completely flameproof construction
4.use fluting replaces wire wound, can manufacture the high resistance range.
5.supper heat dissipation; small linear temperature coefficient.
6. Instant overload capability; without annual shift on resistance value.

electrolytic capacitor

Wednesday, 23. February 2011 5:47

An electrolytic capacitor is a type of capacitor that uses an electrolyte, an ionic conducting liquid, as one of its plates, to achieve a larger capacitance per unit volume than other types. They are often referred to in electronics usage simply as “electrolytics”. They are used in relatively high-current and low-frequency electrical circuits, particularly in power supply filters, where they store charge needed to moderate output voltage and current fluctuations in rectifier output. They are also widely used as coupling capacitors in circuits where AC should be conducted but DC should not. There are two types of electrolytics; aluminum and tantalum.

ET3303 Cermet Trimming Potentiometer

Friday, 11. February 2011 7:03

A potentiometer is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider.If only two terminals are used (one side and the wiper), it acts as a variable resistor or rheostat. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.ET3303 Cermet Trimming Potentiometer is one SMD type potentiometer with single turn,the standard resistance Range is from 100Ω to 1MΩ,the resistance tolerance is±25% std.For this kind of potentiometer,the adjustment angle is 260°normal.It is Rohs compliant.

Disc ceramic capacitors low voltage

Thursday, 10. February 2011 3:25

A ceramic capacitor is a two-terminal, non-polar device. As one kind of ceramic capacitor,ceramic disc capacitors are units used to manage voltage for various dielectric functions in the computer industry. The role of ceramic layers is to dissipate heat which may occur due to high voltage, while protecting the environment-both internal and external  from damage.
