"Base Product Number" (BPN) refers to the fundamental identifier assigned to a component by the manufacturer. This number is used to identify a specific product family or series of components that share common features, characteristics, or functionality. The BPN is usually part of a larger part number or order code that includes additional information, such as variations in packaging, tolerance, voltage ratings, and other specifications.

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.

Shielding in electronic components refers to the practice of enclosing or surrounding sensitive electronic circuits or components with a conductive material to protect them from electromagnetic interference (EMI) or radio frequency interference (RFI). The shielding material acts as a barrier that blocks or absorbs unwanted electromagnetic signals, preventing them from affecting the performance of the electronic device. Shielding can be achieved using materials such as metal enclosures, conductive coatings, or shielding tapes. Proper shielding is essential in electronic design to ensure the reliable operation of electronic devices in environments where electromagnetic interference is present.

Contact finish refers to the surface coating or treatment applied to the electrical contacts of electronic components. This finish is crucial for ensuring reliable electrical connections and preventing corrosion or oxidation of the contacts. Common contact finishes include gold, silver, tin, and nickel, each offering different levels of conductivity, durability, and resistance to environmental factors. The choice of contact finish depends on the specific application requirements, such as operating conditions, cost considerations, and compatibility with other components in the circuit. Selecting the appropriate contact finish is essential for maintaining the performance and longevity of electronic devices.

In the context of electronic components, "Usage" refers to the intended or recommended application or operation of the component within an electronic system. This parameter provides guidance on how the component should be utilized to ensure optimal performance, reliability, and longevity. It may include specifications such as voltage ratings, current ratings, temperature ranges, environmental conditions, and other factors that impact the proper functioning of the component. Understanding and adhering to the usage guidelines provided by the manufacturer is crucial in designing and implementing electronic circuits to prevent damage and ensure the component operates within its specified parameters.

1st Connector is a term used in electronic components to refer to the initial connection point or terminal of a device or component. It is the first point where electrical signals or power are input or output from the component. The 1st connector is crucial for establishing the electrical connection between different components in a circuit or system. It is often labeled or identified to ensure proper installation and connection during assembly. Understanding the 1st connector of electronic components is essential for proper circuit design, troubleshooting, and maintenance of electronic devices.

The term "2nd Connector" in electronic components typically refers to a secondary connection point on a device or component that allows for additional connectivity or functionality. This secondary connector is often used to interface with other devices, circuits, or components in a system. It can serve various purposes such as data transfer, power supply, signal input/output, or control functions. The 2nd Connector is designed to complement the primary connector and expand the capabilities of the electronic component, providing flexibility and versatility in its usage. It is important to understand the specifications and pinout of the 2nd Connector to ensure proper integration and operation within the electronic system.

Contact Finish Thickness refers to the measurement of the layer of conductive material applied to the surfaces of electrical contacts in electronic components. This thickness is critical as it influences the electrical conductivity, solderability, wear resistance, and overall performance of the connection. The materials used for the contact finish can include gold, silver, or other metals, and the specified thickness is designed to ensure reliable operation over the component's lifespan.
