Question 1

What is the Mfr

Accepted Answer

Mfr refers to the component's producing company, whose brand and manufacturing processes directly impact the component's performance, consistency, and traceability, making it a key reference during selection.

Question 2

What is the Series

Accepted Answer

Series indicates a manufacturer’s organized range of components, often named with a common prefix or code, to streamline product selection and ensure compatibility across similar models.

Question 3

What is the Package

Accepted Answer

his term denotes the protective casing (often made of plastic, ceramic, or metal) that encapsulates an integrated circuit, determining its size, reliability, and suitability for different mounting technologies like through-hole or SMT.

Question 4

What is the Base Product Number

Accepted Answer

By using the Base Product Number, manufacturers and customers can efficiently communicate about component families without detailing every specification, streamlining the procurement process.

Question 5

What is the Power Dissipation (Max)

Accepted Answer

Maximum Power Dissipation refers to the highest amount of power that an electronic component or device can continuously convert into heat while maintaining normal functionality and without causing permanent damage. It is a key safety and reliability param

Question 6

What is the Package / Case

Accepted Answer

Package / Case refers to the protective housing that encases an electronic component, providing mechanical support, electrical connections, and thermal management.

Question 7

What is the Product Status

Accepted Answer

Product Status indicates the commercial availability and production stage of the component, such as Active, Not for New Design (NRND), Obsolete, or Last Time Buy (LTB).

Question 8

What is the Millicandela Rating

Accepted Answer

A measure of luminous intensity, quantifying the light output from a source (e.g., LED) in a specific direction. It is a key photometric parameter for characterizing the brightness of indicator lights, display backlights, and optical sensors, with the bas

Question 9

What is the Common Pin

Accepted Answer

A pin that is electrically connected to multiple internal elements or functions within an integrated circuit or multi-pin component. Its primary role is to serve as a shared electrical node, often for critical references like ground (GND), power supply (V

Question 10

What is the Digit/Alpha Size

Accepted Answer

This parameter defines the nominal physical height of a single numeric or alphanumeric character on a segmented or dot-matrix display module, typically measured in millimeters (mm). It is a key dimensional specification that determines the display's legib

Question 11

What is the Voltage - Forward (Vf) (Typ)

Accepted Answer

This parameter specifies the typical forward voltage drop across a semiconductor junction (e.g., in a diode or LED) when conducting a specified test current. It is a key indicator of conduction loss and power efficiency, measured in volts (V). The value i

Question 12

What is the Color

Accepted Answer

A visual attribute determined by the wavelength of light reflected or emitted, used for rapid identification, polarity marking, functional grouping (e.g., resistor bands, LED emission, wire jackets), and status indication of components within a system.

Question 13

What is the Display Type

Accepted Answer

This parameter classifies a visual output device based on its core imaging technology and construction, such as LCD, OLED, LED segment, or VFD. It defines the fundamental method of light modulation or emission, which determines key performance characteris

Question 14

What is the Display Format

Accepted Answer

This parameter defines the visual presentation method of information on a display device, specifying the arrangement and type of data units shown. Common formats include numeric (e.g., 7-segment, 14-segment), alphanumeric (character matrix), graphical (pi

Question 15

What is the Size / Dimension

Accepted Answer

This parameter specifies the physical measurements of a component, typically expressed as length, width, height, and/or diameter in millimeters or inches. It defines the component's spatial footprint, which is critical for mechanical integration, PCB layo

Question 16

What is the Current - Test

Accepted Answer

This parameter specifies the magnitude of direct or alternating current, measured in Amperes (A) or milliamperes (mA), applied to a component during a standardized characterization or qualification test. It defines the precise electrical stimulus used to

Question 17

What is the Number of Characters

Accepted Answer

This parameter specifies the total quantity of individual alphanumeric or symbolic units that a display module or component can present simultaneously. It defines the information density and is a primary specification for selecting devices like segmented

Question 18

What is the Wavelength - Peak

Accepted Answer

The specific wavelength at which a light-emitting component, such as an LED or laser diode, emits its maximum radiant intensity or optical power. Measured in nanometers (nm), this parameter is critical for defining the component's color in the visible spe
