Any one knows something about a thyristor with following labels:
ES 15421 9048
Some one says that it is a product of PGS S.P.A from Italy.
Any one knows about this company?
Any one has a datasheet or photo or any information about this part# and its manufacturer?
Thanks before.
prananm77, Thank you for your reply.
The two additional contacts I mentioned, are normally covered by a piece of paper and are not used normally. They may be used in manufacturing process. I need to know the manufacturers for what uses these contacgts?
I looked carefully to mobile phone batteries. They are not simple batteries.
They are a Li battery connected to a circuit that has one or more ICs and resistors and capacitors.
There are 3 or 4 main contacts on a mobile phone battery that is used normally by the phone.
There are also two...
rectifier handbook
I need a book about "Capacitor-Diode Voltage Multiplier" like following Handbook:
G. J. Scoles, Handbook of Rectifier Circuits. Chichester: Wiley, 1980
Any one can helps me?
definition of resistor withstanding voltage
to FANT:
If you look at High Voltage resistor manufacturer, you will find high voltage resistor with resistance value more than 10GΩ (10,000 MΩ) and voltage ratings above 20,000 Volts. 100MΩ is completely practical in high voltage circuits.
for...
dielectric withstand voltage
You are right, but what confusing me is that “Dielectric Withstanding Voltage” for a 40KV resistor (100MΩ) is only 700V or at most 1000V (as in manufacturers datasheet). does it mean the dielectric will damage in rated voltage? If no, what does it means?
dielectric withstanding voltage
I need to know what does “Dielectric Withstanding Voltage” means in a high voltage resistor, as in a resistor the voltage is applied to its leads which are metal not dielectric.
In a capacitor, “Dielectric Withstanding Voltage” has a clear meaning because the...
abb tecnomasio
Hi all
All need to know more about this company: ABB Technomasio S.p.A
I mean:
1) Company web site address
2) Address, Phone, Fax, e-mail
3) working fields
4) Products
5) Size of Company
6) history
7) head office address and country
8) Representatives in other countries...
More than 25 times your topic is viewed but there is no answer for you inspite of that it seems your question is an elementary question. I think it is because others like me can not understand what you mean from your word!
I suggest you to explain your question more and with better words. Hope...
It depends on transistor type, its specification and your voltage source type and pulse duration and period. In the transistor datasheet, there is a section called MAXIMUM RATINGS. Look in this section for maximum allowable Ib (base current). You should calculate if the base current goes near...
matlab to c conversion function
I think you should search for "Compile" instead of "Convert" and "Matlab function" instead of "matlab code".
I guess it is a standard proccess to compile a matlab function to a C function (may be called C-MEX function). Look for these keywords in Matlab help.
As I remember, in physics laboratiry, there was a vandergraph generator with a metalic sphere that generates charges on that metalic sphere, am I right?
Dear vikramc98406
I did not understand exactly what you mean, but damages that is caused by static charges in electronics parts is generally introduced in parts that have a pure capacitance such as a MOSFET gate.
To understand this, suppose a real MOSFET gait pin that can be modeled as a...
The reason of limited voltage in capacitors is not limitation of electrons count in its plate. A 1000µF, 100V capacitors may weight more than 10 grams and each of its plates weight more than 1 grams. Each 1 grams of Aluminium plate, has about 1e21 atoms of Aluminium and if all of its atoms are...
