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 Current - Surge

Accepted Answer

Surge Current refers to a high-magnitude, short-duration (typically microseconds to milliseconds) peak current that flows through a device or circuit during initial power-up, load step change, or external disturbance (e.g., lightning induction).

Question 6

What is the Package / Case

Accepted Answer

Package / Case refers to the protective housing that encases an electronic component, providing mechanical support, electrical connections, and thermal management.

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 Circuits

Accepted Answer

This specifies the quantity of independent functional amplifier circuits contained within a single integrated circuit (IC) package.

Question 9

What is the Varistor Voltage (Max)

Accepted Answer

This parameter specifies the maximum voltage across the device's terminals at which its impedance remains very high, effectively defining the upper boundary of its normal operating range before it begins to conduct significantly. It is the voltage at whic

Question 10

What is the Varistor Voltage (Min)

Accepted Answer

This parameter specifies the minimum voltage at which the device begins to exhibit a significant decrease in resistance, transitioning from its high-impedance state. It defines the lower threshold for the protective clamping action, ensuring the component

Question 11

What is the Varistor Voltage (Typ)

Accepted Answer

This parameter specifies the typical voltage at which the metal-oxide varistor (MOV) begins to conduct significantly, measured across its terminals with a defined test current (usually 1mA DC). It defines the clamping threshold for transient voltage suppr

Question 12

What is the Maximum AC Volts

Accepted Answer

This parameter specifies the highest root-mean-square (RMS) alternating current voltage that a component or device can safely withstand across its terminals without risk of insulation breakdown, arcing, or permanent damage. It is a critical safety rating

Question 13

What is the Maximum DC Volts

Accepted Answer

The highest continuous direct current potential difference a component can withstand without breakdown or performance degradation, measured in volts (V). This absolute maximum rating defines the upper safety limit for voltage stress across terminals, such

Question 14

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 15

What is the Energy

Accepted Answer

A fundamental physical quantity representing the capacity of a system to perform work, measured in Joules (J). In electronics, it is the integral of power over time, governing the total work done or heat dissipated by a circuit. It is the key parameter fo

Question 16

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
