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 Breaker Type

Accepted Answer

Breaker Type refers to the systematic classification of circuit protective breakers based on their protection principle, arc-extinguishing medium, or application. Its core function is to automatically interrupt current in the event of overload, short circ

Question 6

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 7

What is the Voltage Rating - AC

Accepted Answer

This parameter specifies the maximum root-mean-square (RMS) alternating current voltage a component can safely withstand continuously across its terminals or insulation without risk of breakdown, performance degradation, or safety hazard. It is a critical

Question 8

What is the Voltage Rating - DC

Accepted Answer

It specifies the maximum direct current potential difference a component, device, or insulating material can continuously withstand without risk of performance degradation or failure. This absolute maximum rating, measured in volts (V DC), defines the upp

Question 9

What is the Number of Poles

Accepted Answer

It specifies the count of completely isolated and independently switchable electrical circuits within a single mechanical actuator of a switch, relay, or circuit breaker. For example, a single-pole (SP) device controls one circuit, while a double-pole (DP

Question 10

What is the Illumination Voltage (Nominal)

Accepted Answer

This parameter specifies the standard operating voltage required to power the internal light source (e.g., an LED or incandescent bulb) within an illuminated component, such as a switch or indicator. It is the primary electrical design value for the illum

Question 11

What is the Illumination

Accepted Answer

The luminous flux incident on a surface per unit area, measured in lux (lx) or foot-candles (fc). It quantifies the amount of visible light reaching a target, which is critical for designing sensor systems (e.g., photoelectric, imaging), specifying displa

Question 12

What is the Actuator Type

Accepted Answer

Actuator Type refers to the fundamental classification of a device that converts an input energy source into controlled mechanical motion. It is defined by its core operating principle, such as electric (solenoid, motor), pneumatic (cylinder), hydraulic (

Question 13

What is the Approval Agency

Accepted Answer

A designated organization that validates a component's compliance with specific safety, performance, or environmental standards (e.g., UL, CE, CSA). This certification is a mandatory requirement for market access, ensuring the product meets regional regul

Question 14

What is the Current Rating (Amps)

Accepted Answer

Specifies the maximum continuous current a conductor, connector, or component can safely carry without exceeding its thermal limits, thereby preventing overheating and ensuring long-term reliability. This ampere (A) rating is a fundamental parameter for s

Question 15

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
