What does Y stand for on a circuit board?
Designators
| Designator | Component type |
|---|---|
| X | Socket connector for another item not P or J, paired with the letter symbol for that item (XV for vacuum tube socket, XF for fuse holder, XA for printed circuit assembly connector, XU for integrated circuit connector, XDS for light socket, etc.) |
| XTAL | Crystal |
| Y | Crystal or oscillator |
What is RT in PCB?
Highly likely that RT means Resistor – Temperature (dependant).
What is the symbol for a DIAC?
DIAC is given by the symbol of two Diodes connected in parallel and opposite to one another and has two terminals. Since the DIAC is bidirectional, we can’t name those terminals as anode and cathode, the terminals of DIAC are simply called A1 and A2 or MT1 and MT2 where MT stands for Main terminals.
What does U1 mean on a circuit board?
I have been digging into the mouse PCB and found few IC’s on it. Through google, I found that the IC (termed as “U1”) is an optical sensor and the IC (termed as “U3”) is the controller IC.
What does PCB stand for AC?
A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate.
Why are relays labeled K?
Countries using American standards use IEEE Std 315-1975 / ANSI Y32. 2, Graphic symbols for electrical and electronic diagrams. Relays are called ‘K’ because IEC 60750 and IEEE 315 say so. Unfortunately, ‘relay coil’ translates to ‘relaisspule’ and ‘contactor’ translates to ‘schütz’.
What is cr in electrical schematics?
A coil is commonly symbolized as a circle with letters and number inside. The letters often represent the type of device, such as M for motor starter or CR for control relay. A coil often controls multiple contacts and each contact may be normally open or normally closed.
Is a DIAC a thyristor?
DIAC stands for “Diode for Alternating Current”. A DIAC is a device which has two electrodes, and it is a member of the thyristor family.
What is J on a PCB?
Integrated circuit – an alternative widely used non-standard abbreviation. J. Connector jack (normally but not always refers to female contact)
What is inverter AC?
In an inverter air conditioner, an inverter continuously regulates the temperature by controlling the speed of the compressor motor. This technology, also known as DC inverter; it has a variable frequency drive that controls the speed of the electromotor. This makes inverter conditioners a powerful energy saver.
What is compressor in AC?
In a split air conditioning system—the standard central AC found in most homes—the compressor is located in the outdoor unit. Its job is to circulate the refrigerant necessary for heat exchange through the coils of the indoor and outdoor unit, and also to apply the energy to the refrigerant.
