Table dBm - dBu - voltage - S-units

Tabela de Conversão dBm x Watts x Volts

This is a dBm table, dBu ,Tension and Units-S (S-units) . dBm, dBu voltage and metric units are well known, Units already-S (S-units) It is somewhat unknown to those who do not work in the radio frequency area. S-units meter is a kind of signal strength meter, a widely used gauge in communications receivers , such as amateur radio receivers or ...

ELF frequencies

ELF frequencias

ELF é a sigla do inglês de frequência extremamente baixa (Extremely Low Frequency), of electromagnetic radiation band, with frequency 3 a 30 Hz , and the corresponding lengths of a wave 100.000 a 10.000 km. ELF radio waves are generated by lightning or natural disturbances in the Earth's magnetic field. Devido à dificuldade de construção de antenas ...

What is EMF

Espectro Eletromagnético

EMF significa campo eletromagnético, que são muitas vezes chamados de CEM, as forças elétricas e magnéticas invisíveis. CEM são um tipo de radiação, que tomam a forma de ondas. Tipos de Energias Eletromagnéticas CEM Naturais A terra produz um campo eletromagnético, o corpo humano também o produz, esses campos são de frequências extremamente baixas conhecidas com ELF. Really, a investigação científica tem demonstrado ...

Esquema Eletrônico – Diagrama de Blocos

Esquema Eletrônico

Here I will start a series of articles that IRAM turn into an ebook about electronics for beginners. I will try to use simple language and an approach to understanding people who have no knowledge in electronics. I believe that I will be criticized for the way that I will explain, but I want to somehow contribute to the increase of hobbyists and professionals. In ...

Tabela de Logotipos de fabricantes de Componentes Semicondutores

Logomarcas e nomes

Um logo, logotipo ou logomarca é a representação gráfica de uma marca ou empresa, que geralmente acaba por determinar uma identidade visual e facilitar o seu reconhecimento sem a necessidade da escrita do nome. A logomarca realmente é uma maneira mais simples de identificar o fabricante de um determinado produto. Muitas vezes estamos trabalhando e encontramos um componente (semicondutor) que queremos saber o ...

Comparison of CMOS Technologies, BJT, e GaAs

Transistor SMD 1p - 2n2222

Here's a little comparison table between CMOS technologies, BJT e GaAs. CMOS or MOS-C is the acronym for complementary metal-oxide-semiconductor, it is a technology for building integrated circuits used in microprocessors very, BJT é a sigla de Bipolar junction transistor, is the fastest technology for transistors due to its ease of polarization and high durability. Já GaAs, or gallium arsenide is ...

Codes SMD Transistors and Diodes – SMD CODE

Transistor SMD 1p - 2n2222

Due to the small size SMD semiconductor, as transistors and diodes boss took another code. In the case of transistors and diodes would be very difficult to put a mark, at a microscopic example 2N2222 component, it even more difficult to be identified. Then a new code was created in these semiconductors, a new encoding system, a simple identification code ...
