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 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 6

What is the Focal Length

Accepted Answer

It defines the distance from the optical center of a lens to its focal point where parallel incoming light rays converge, measured in millimeters (mm). This parameter determines the lens's magnification power and field of view; a shorter value provides a

Question 7

What is the Beam Diameter

Accepted Answer

The cross-sectional width of a laser or light beam, typically measured at the point where its intensity falls to 1/e² (approximately 13.5%) of its peak axial value. This parameter, usually specified in millimeters (mm) or micrometers (µm), defines the spo

Question 8

What is the Lens Material

Accepted Answer

The substance from which an optical lens is fabricated, such as optical glass (e.g., BK7, SF11), plastics (e.g., PMMA, polycarbonate), or crystalline materials (e.g., sapphire, silicon). Its intrinsic properties—including refractive index, Abbe number (di

Question 9

What is the Wavelength

Accepted Answer

The distance between successive crests of an electromagnetic wave, measured in nanometers (nm) or micrometers (µm). It determines the wave's energy and its interaction with matter, defining the color of light in the visible spectrum and the absorption/tra

Question 10

What is the Features

Accepted Answer

These are the additional, non-core capabilities or characteristics integrated into a component beyond its primary function. They enhance performance, reliability, or ease of use, such as built-in protection (thermal shutdown, overcurrent), enable/disable
