Package / Case refers to the physical housing or enclosure that encapsulates an electronic component. It provides protection, facilitates handling, and enables electrical connections. The package type determines the component's size, shape, pin configuration, and mounting options. Common package types include DIP (dual in-line package), SOIC (small outline integrated circuit), and BGA (ball grid array). The package also influences the component's thermal and electrical performance.

Series, in the context of electronic components, refers to the arrangement of components in a circuit. When components are connected in series, they form a single path for current to flow through. The total resistance of a series circuit is the sum of the individual resistances of each component. Series connections are often used to control the flow of current in a circuit, as the total resistance can be adjusted by changing the number or type of components in the series.

Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.

Moisture Sensitivity Level (MSL) is a measure of the susceptibility of a surface mount electronic component to moisture-induced damage during soldering. It is classified into six levels, from 1 (least sensitive) to 6 (most sensitive). MSL is determined by the materials used in the component's construction, including the solderability of its terminals and the presence of moisture-absorbing materials. Components with higher MSL ratings require more stringent handling and storage conditions to prevent moisture absorption and subsequent damage during soldering.

Temperature Coefficient (TC) measures the relative change in a component's value due to temperature variations. It is expressed as a percentage change per degree Celsius (°C). A positive TC indicates an increase in value with increasing temperature, while a negative TC indicates a decrease. TC is crucial for ensuring stable circuit performance over a range of temperatures. It helps designers compensate for temperature-induced changes and maintain desired component characteristics.

Resistance is a measure of the opposition to the flow of electric current in a conductor. It is measured in ohms (Ω). The higher the resistance, the more difficult it is for current to flow. Resistance is caused by the collisions of electrons with atoms and molecules in the conductor. The more collisions that occur, the higher the resistance.

Height, in the context of electronic components, refers to the vertical dimension of the component. It is typically measured in millimeters (mm) or inches (in). Height is an important parameter to consider when designing and assembling electronic circuits, as it affects the overall size and form factor of the device. Components with a smaller height are often preferred for applications where space is limited, such as in portable devices or embedded systems.
