Supplier Device Package refers to the specific nomenclature or code used by a component manufacturer or distributor (supplier) to designate the physical outline and pin arrangement of an electronic component they produce or sell.

Question 6

What is the Frequency

Accepted Answer

Frequency is the number of occurrences of a repeating event per unit of time, with the base unit of Hertz (Hz).

Question 7

What is the Memory Size

Accepted Answer

The total data storage capacity of a semiconductor memory device, measured in bits, bytes, or their multiples (e.g., KB, MB, GB). It defines the maximum amount of program code or data the device can hold, directly determining its application scope in syst

Question 8

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 9

What is the Type

Accepted Answer

This parameter categorizes a component based on its fundamental operating principle, internal structure, or primary application domain. It serves as the highest-level identifier, grouping devices with shared core characteristics—such as "N-Channel MOSFET,

Question 10

What is the GPIO

Accepted Answer

A configurable digital pin on an integrated circuit that can be programmed by software to function as either an input (to read a logic state) or an output (to drive a logic state). It provides a direct, bit-level interface between a microcontroller or pro

Question 11

What is the Modulation

Accepted Answer

A technique for encoding information onto a carrier signal by systematically varying one or more of its properties—amplitude, frequency, or phase. This process enables the efficient transmission of data over long distances via wired or wireless channels,

Question 12

What is the RF Family/Standard

Accepted Answer

This term categorizes a wireless communication device or module based on the specific radio frequency protocol, air interface, and network architecture it implements. It defines the fundamental operating rules for spectrum access, modulation, data framing

Question 13

What is the Serial Interfaces

Accepted Answer

These are dedicated hardware or software-defined communication channels that enable sequential, bit-by-bit data transfer between a host device (e.g., microcontroller) and peripherals. Common standards include UART (asynchronous), SPI (synchronous, full-du

Question 14

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 15

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 16

What is the DigiKey Programmable

Accepted Answer

A service offering that allows customers to configure specific parameters of a component (e.g., memory size, clock frequency, or firmware) at the point of order. This enables the manufacturer to produce a custom variant from a base product, providing appl

Question 17

What is the Voltage - Supply

Accepted Answer

The nominal DC potential difference applied to the power input pin(s) of an integrated circuit or module, measured in volts (V). It defines the required energy level for proper operation and establishes the reference for internal logic levels and analog s

Question 18

What is the Power - Output

Accepted Answer

This parameter specifies the maximum continuous electrical power a device can deliver to its load under nominal operating conditions, measured in Watts (W). It is a key performance rating for power supplies, amplifiers, transmitters, and motor drivers, de

Question 19

What is the Sensitivity

Accepted Answer

Sensitivity quantifies the magnitude of a device's output signal change in response to a given change in the measured input quantity. It is a key transfer function parameter, typically expressed in units like mV/V for sensors, µV/Pa for microphones, or V/

Question 20

What is the Protocol

Accepted Answer

A set of formal rules and conventions governing the format, timing, sequencing, and error control of data exchange between two or more devices or systems. It defines the syntax, semantics, and synchronization of communication, ensuring interoperability re

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 Current - Receiving

Accepted Answer

The maximum continuous current that a device's input port or power pin is designed to safely accept from an external source to ensure proper operation. This rating, measured in Amperes (A), defines the upper limit of the device's power consumption under n

Question 23

What is the Data Rate (Max)

Accepted Answer

This parameter specifies the highest speed at which a digital communication interface, such as a serial bus or transceiver, can reliably transfer data. It is typically measured in bits per second (bps) or its multiples (e.g., Mbps, Gbps). This maximum rat

Question 24

What is the Current - Transmitting

Accepted Answer

This parameter specifies the maximum continuous current that a component, such as a connector, cable, or PCB trace, is designed to carry from a source to a load without exceeding its thermal or electrical limits. It is a critical rating for ensuring relia
