Static Pressure refers to the pressure exerted by a fluid (typically air) perpendicular to its direction of flow, and in electronics, it is a key fan specification measured in Pascals (Pa) or inches of water (inH₂O) that indicates the fan's ability to ove

Question 7

What is the RPM

Accepted Answer

Revolutions Per Minute (RPM) is the rotational speed unit for rotating machinery (e.g., motors, fans), indicating the number of complete turns a shaft makes per minute.

Question 8

What is the Voltage - Rated

Accepted Answer

Voltage - Rated refers to the operating voltage that a device, component, or insulation material is designed to withstand continuously.

Question 9

What is the Material - Frame

Accepted Answer

The primary substance used to construct the structural housing or chassis of a component, such as a connector, fan, or display module. This material determines key mechanical properties including rigidity, weight, corrosion resistance, and electromagnetic

Question 10

What is the Material - Blade

Accepted Answer

The specific substance used to fabricate the cutting or engaging portion of a tool or contact, such as a screwdriver bit or terminal. Its mechanical properties, including hardness, wear resistance, and toughness, directly determine the tool's durability,

Question 11

What is the Air Flow

Accepted Answer

This parameter quantifies the volumetric flow rate of air moved by a cooling device, such as a fan or blower, typically measured in cubic feet per minute (CFM) or cubic meters per hour (m³/h). It is a primary performance metric defining the device's capac

Question 12

What is the Width

Accepted Answer

Width refers to the lateral dimension of an electronic component, measured perpendicular to its length and height. It is a critical physical parameter that defines the component's footprint on a printed circuit board (PCB) and influences layout density, m

Question 13

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 14

What is the Weight

Accepted Answer

A fundamental physical property measured in grams (g) or kilograms (kg), it quantifies the mass of a component. This parameter is critical for structural design, load calculations, and ensuring mechanical integrity in applications where mass impacts perfo

Question 15

What is the Power (Watts)

Accepted Answer

It quantifies the rate of energy transfer or conversion within an electrical system, measured in Joules per second. This fundamental parameter defines the capacity of a source to deliver energy or the amount consumed by a load. In component specifications

Question 16

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 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 Voltage Range

Accepted Answer

Specifies the minimum and maximum electrical potential difference, measured in volts (V), that can be safely and reliably applied to a component's input or across its terminals. This defines the operational boundaries for power supply rails, signal inputs

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 Bearing Type

Accepted Answer

This parameter classifies the mechanical interface that supports and guides the relative motion between two parts, primarily based on the nature of the contact and load direction. Core types include ball bearings (handling radial and axial loads with low

Question 21

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 22

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 23

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 24

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 25

What is the Lifetime @ Temp.

Accepted Answer

This parameter specifies the expected operational duration, typically in hours, that a component (such as an electrolytic capacitor or LED) can maintain its specified performance when continuously operated at a declared ambient temperature. It is a key re

Question 26

What is the Fan Type

Accepted Answer

This parameter classifies cooling fans based on their core airflow generation mechanism and physical construction. Primary categories include Axial (airflow parallel to the shaft), Centrifugal/Radial (airflow perpendicular to the shaft), and Blower types.
