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 Contact Material

Accepted Answer

Contact Material refers to the specific metal or alloy used at the interface where two conductors meet to establish an electrical path in connectors, switches, or relays. Its core properties include conductivity (affecting contact resistance), hardness (a

Question 6

What is the Number of Positions/Bay/Row

Accepted Answer

This parameter specifies the quantity of individual contact locations within a single modular segment or linear arrangement of a multi-position connector or terminal block. It defines the connection density for a given physical footprint, directly determi

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 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 9

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 10

What is the Termination Rows

Accepted Answer

This parameter specifies the number of horizontal rows of electrical connection points (e.g., pins, solder pads, screw terminals) arranged on a component, such as a connector or terminal block. It is a fundamental mechanical specification that defines the

Question 11

What is the Gender

Accepted Answer

The physical configuration of a connector's mating interface, specifying whether it presents pins (male) or sockets (female). This fundamental mechanical attribute ensures correct and secure mating between complementary pairs, preventing incorrect connect

Question 12

What is the Contact Finish

Accepted Answer

A conductive surface treatment applied to the electrical contact areas of connectors, switches, or relay terminals. Its primary functions are to protect the base metal from oxidation and corrosion, reduce contact resistance, and enhance solderability and

Question 13

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 14

What is the Read Out

Accepted Answer

A dedicated circuit or subsystem within a sensor or integrated circuit that converts a raw, internal analog signal (e.g., from a sensing element) into a standardized, usable digital format. Its core function is to provide an accessible, conditioned output

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 Card Type

Accepted Answer

A standardized classification for removable circuit boards based on their physical form factor, electrical interface, and intended function within a host system. It defines the mechanical dimensions, connector pinout, and key electrical specifications, en

Question 17

What is the Card Thickness

Accepted Answer

This parameter specifies the nominal thickness of a printed circuit board (PCB) or electronic module designed for insertion into a card-edge connector or slot, such as a PCIe card or memory module. It is a critical mechanical dimension, typically measured

Question 18

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 19

What is the Termination

Accepted Answer

The specific method and hardware used to establish a permanent or semi-permanent electrical and mechanical connection at the end of a wire, cable, or component lead. Common methods include soldering, crimping, screw clamping, insulation displacement, and

Question 20

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 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

Question 22

What is the Contact Finish Thickness

Accepted Answer

This parameter specifies the vertical dimension of the metallic plating layer applied to the electrical contact surfaces of a connector, switch, or relay terminal. Measured in micrometers (µm) or microinches (µ-in), it is a critical determinant of the con

Question 23

What is the Material - Insulation

Accepted Answer

A dielectric substance used to electrically isolate conductive elements, preventing current leakage and short circuits. Its primary function is to ensure operational safety and signal integrity. Key properties include dielectric strength (kV/mm), volume r

Question 24

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
