The "Mounting Type" in electronic components refers to the method used to attach or connect a component to a circuit board or other substrate, such as through-hole, surface-mount, or panel mount.

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

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 power supply may fail.

In electronic components, the "Series" refers to a group of products that share similar characteristics, designs, or functionalities, often produced by the same manufacturer. These components within a series typically have common specifications but may vary in terms of voltage, power, or packaging to meet different application needs. The series name helps identify and differentiate between various product lines within a manufacturer's catalog.

In electronic components, the parameter "Size / Dimension" refers to the physical dimensions of the component, such as its length, width, and height. These dimensions are crucial for determining how the component will fit into a circuit or system, as well as for ensuring compatibility with other components and the overall design requirements. The size of a component can also impact its performance characteristics, thermal properties, and overall functionality within a given application. Engineers and designers must carefully consider the size and dimensions of electronic components to ensure proper integration and functionality within their designs.

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

Moisture Sensitivity Level (MSL) is a standardized rating that indicates the susceptibility of electronic components, particularly semiconductors, to moisture-induced damage during storage and the soldering process, defining the allowable exposure time to ambient conditions before they require special handling or baking to prevent failures

An ECCN (Export Control Classification Number) is an alphanumeric code used by the U.S. Bureau of Industry and Security to identify and categorize electronic components and other dual-use items that may require an export license based on their technical characteristics and potential for military use.

The parameter "Applications" in electronic components refers to the specific uses or functions for which a component is designed. It encompasses various fields such as consumer electronics, industrial automation, telecommunications, automotive, and medical devices. Understanding the applications helps in selecting the right components for a particular design based on performance, reliability, and compatibility requirements. This parameter also guides manufacturers in targeting their products to relevant markets and customer needs.

The parameter "Current Rating (Amps)" in electronic components refers to the maximum amount of electrical current that the component can safely handle without being damaged. It is typically measured in amperes (A) and is an important specification to consider when designing or selecting components for a circuit. Exceeding the current rating of a component can lead to overheating, malfunction, or even failure of the component. It is crucial to ensure that the current rating of a component matches the requirements of the circuit to prevent any potential issues and ensure reliable operation.

Voltage - Rated AC is a parameter that specifies the maximum alternating current (AC) voltage that an electronic component can safely handle without being damaged. This rating is crucial for ensuring the proper functioning and longevity of the component within an electrical circuit. It is typically expressed in volts (V) and helps users determine the compatibility of the component with the voltage levels present in the circuit. Exceeding the rated AC voltage can lead to overheating, malfunction, or permanent damage to the component, so it is important to adhere to this specification when designing or using electronic systems.

The parameter "Approval Agency" in electronic components refers to the organization responsible for testing and certifying that a component meets specific safety, quality, and performance standards. These agencies evaluate products to ensure compliance with industry regulations and standards, providing assurance to manufacturers and consumers. Approval from recognized agencies can enhance a component's marketability and acceptance in various applications, particularly in sectors like automotive, aerospace, and healthcare. Common approval agencies include Underwriters Laboratories (UL), International Electrotechnical Commission (IEC), and the American National Standards Institute (ANSI).

the time taken for a circuit or measuring device, when subjected to a change in input signal, to change its state by a specified fraction of its total response to that change.

In electronic components, the "Fuse Type" parameter refers to the type of fuse used in the component for overcurrent protection. Fuses are devices designed to interrupt the flow of current in a circuit when the current exceeds a certain threshold, thereby protecting the circuit from damage due to overcurrent conditions. The fuse type can vary based on factors such as the current rating, voltage rating, size, and construction of the fuse. Common fuse types include fast-acting, slow-blow, resettable (PTC), and thermal fuses, each with specific characteristics and applications. Selecting the appropriate fuse type is crucial to ensure the safety and reliability of the electronic circuit.

Breaking Capacity at Rated Voltage refers to the maximum fault current that an electrical device, such as a fuse or circuit breaker, can safely interrupt without damage. This parameter indicates the ability of the device to protect the electrical circuit by successfully breaking the circuit under short-circuit conditions. It is crucial for ensuring safety and reliability in electrical systems, as exceeding this capacity may result in catastrophic failure or fire hazards.

Melting I2t is a parameter used to describe the thermal energy required to melt a fuse element when a current flows through it. It is a measure of the energy dissipated in the fuse element due to the square of the current multiplied by the time it flows through the element. This parameter helps determine the ability of a fuse to safely interrupt a fault current without causing damage to the circuit or surrounding components. In essence, the melting I2t value indicates the fuse's thermal response to overcurrent conditions and its ability to protect the circuit from damage.

Circuit Protection Type refers to the specific method or device used to safeguard electronic circuits from overcurrent, overvoltage, and other potentially damaging electrical conditions. This can include fuses, circuit breakers, transient voltage suppressors, and other protective components designed to prevent equipment failure or damage. Each protection type has its own characteristics, response times, and applications, making it essential to select the appropriate type based on the specific requirements of the circuit design.

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
