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 Supplier Device Package

Accepted Answer

Supplier Device Package refers to the specific nomenclature or code used by a component manufacturer or distributor (supplier) to designate the physical outline and pin arrangement of an electronic component they produce or sell.

Question 6

What is the Lumens/Watt @ Current - Test

Accepted Answer

Lumens/Watt @ Current - Test is a measure of a light source's efficiency in converting electrical energy to light at a given operating current.

Question 7

What is the Height - Seated (Max)

Accepted Answer

This parameter specifies the maximum vertical dimension from the mounting surface (e.g., PCB) to the highest point of a component when it is fully seated and soldered in place. It is a critical mechanical clearance specification for determining the minimu

Question 8

What is the CCT (K)

Accepted Answer

Correlated Color Temperature quantifies the hue of white light emitted by a source, measured in Kelvin (K). It describes the perceived warmth or coolness of the light by comparing it to the color of a theoretical black-body radiator at a specific temperat

Question 9

What is the CRI (Color Rendering Index)

Accepted Answer

A dimensionless metric (0-100) quantifying how accurately a light source reveals the true colors of objects compared to a reference illuminant of the same correlated color temperature. A higher value indicates superior color fidelity, which is critical fo

Question 10

What is the Flux @ 25°C, Current - Test

Accepted Answer

This parameter specifies the total luminous flux, measured in lumens (lm), emitted by a light source (typically an LED) when it is operated at a specified test current and its junction has stabilized at a temperature of 25°C. It is the definitive metric f

Question 11

What is the Flux @ 85°C, Current - Test

Accepted Answer

This parameter specifies the total luminous flux (in lumens, lm) emitted by a light source, typically an LED, when it is operated at a specified test current and its junction has reached a stabilized temperature of 85°C. It characterizes the light output

Question 12

What is the Thermal Resistance of Package

Accepted Answer

A measure of a semiconductor package's ability to dissipate heat from the junction to the ambient environment, expressed in degrees Celsius per watt (°C/W). It quantifies the temperature rise per unit of power dissipated, with lower values indicating supe

Question 13

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 14

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 15

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 16

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 17

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 18

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 19

What is the Viewing Angle

Accepted Answer

The angular range, measured in degrees, over which a display or optical sensor maintains acceptable performance in contrast, color accuracy, and brightness. It is defined by the off-axis angle at which the luminance or contrast ratio falls to a specified

Question 20

What is the Current - Max

Accepted Answer

The maximum continuous current that a component, device, or conductor can safely carry without exceeding its thermal or electrical limits, resulting in permanent degradation or failure. This absolute maximum rating, measured in Amperes (A), is a critical

Question 21

What is the Mounting Type

Accepted Answer

Mounting Type refers to the standardized classification of the method by which an electronic component or module is physically secured and electrically connected to a printed circuit board, chassis, or panel. It defines how the component integrates into t
