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 Shell Material, Finish

Accepted Answer

Shell Material, Finish refers to two distinct yet related specifications: the Material denotes the base substance (e.g., plastic, aluminum alloy) forming the component's protective housing, while the Finish describes the surface treatment (e.g., plating,

Question 6

What is the Note

Accepted Answer

Note refers to the supplementary text, exceptions, warnings, or application guidance attached to specific parameters, specifications, or diagrams in technical documents, datasheets, or drawings.

Question 7

What is the Shell Size, Connector Layout

Accepted Answer

Shell Size (code) defines the physical dimensions of a connector, while Connector Layout specifies the arrangement of its internal contacts.

Question 8

What is the Mating Cycles

Accepted Answer

The specified number of times a separable electrical connector can be successfully mated (connected) and unmated (disconnected) while maintaining its electrical and mechanical performance within datasheet specifications. This rating is a key reliability m

Question 9

What is the Shell Finish Thickness

Accepted Answer

This parameter specifies the vertical dimension of the surface treatment layer (e.g., plating, anodizing, painting) applied to a connector's metallic shell or housing. Measured in micrometers (µm) or mils, it is a critical determinant of the finish's dura

Question 10

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 11

What is the Number of Rows

Accepted Answer

It specifies the count of parallel contact or pin arrays in a connector, switch, or IC package, directly determining the total pin count when multiplied by the number of columns. This dimension is critical for defining the component's footprint, mating in

Question 12

What is the Operating Temperature

Accepted Answer

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the powe

Question 13

What is the Connector Type

Accepted Answer

A standardized classification for electrical interfaces based on their mechanical form, mating mechanism, and electrical characteristics. It defines the physical and electrical compatibility between mated pairs, ensuring reliable signal and power transmis

Question 14

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 15

What is the Contact Type

Accepted Answer

This parameter defines the physical form and operational mechanism of the conductive interface within a connector, switch, or relay. Common types include pin/socket, blade/receptacle, spring-loaded, and surface-mount pads. The selection dictates mating fo

Question 16

What is the Flange Feature

Accepted Answer

A mechanical design element on a component's housing, such as a protruding rim or lip with mounting holes, that provides a robust interface for secure attachment to a chassis, panel, or heat sink using screws or bolts. Its primary function is to ensure me

Question 17

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

Question 18

What is the Ingress Protection

Accepted Answer

A standardized rating system (IEC 60529) that classifies the degree of protection provided by an enclosure against the intrusion of solid objects (first digit) and liquids (second digit). It quantifies resistance to dust, accidental contact, and water ing

Question 19

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

Question 20

What is the Connector Style

Accepted Answer

This parameter categorizes the physical form and mating interface of an electrical connector, such as rectangular, circular, D-sub, or card-edge. It defines the mechanical outline, keying features, and engagement method, which directly determines compatib

Question 21

What is the Number of Positions

Accepted Answer

It specifies the total count of individual, electrically distinct connection points or terminals available within a single connector, switch, relay, or terminal block. This fundamental parameter defines the component's capacity for establishing independen

Question 22

What is the Dielectric Material

Accepted Answer

A dielectric material is an electrical insulator that can be polarized by an applied electric field. Its primary function is to store electrostatic energy and provide electrical isolation between conductors. The key property is its dielectric constant (k)
