"Termination style" in electronic components refers to the method used to connect the component to a circuit board or other electronic devices. It determines how the component's leads or terminals are designed for soldering or mounting onto the circuit board. Common termination styles include through-hole, surface mount, and wire lead terminations.Through-hole components have leads that are inserted through holes in the circuit board and soldered on the other side. Surface mount components have flat terminals that are soldered directly onto the surface of the circuit board. Wire lead terminations involve attaching wires to the component for connection.The choice of termination style depends on factors such as the type of component, the manufacturing process, and the space available on the circuit board. Different termination styles offer various advantages in terms of ease of assembly, reliability, and space efficiency in electronic designs.

The current rating of a contact is defined as the current level that creates a certain temperature rise of the contact spring — usually 20°C or 30°C. Both electrical and thermal factors govern the heat created by the current.

On most company websites, email and mailing addresses are also included; however, the contact form provides an immediate, convenient way for users to ask the company questions.

Contact arrangement in electronic components refers to the configuration and organization of electrical contacts within a switch, relay, or connector. It defines how contacts are paired or grouped, determining their functionality in terms of opening or closing circuits, switching pathways, or making connections. Different contact arrangements, such as normally open, normally closed, or various multi-pole configurations, affect the behavior of the component in electronic circuits, influencing design choices based on the desired electrical performance.

A coil spike suppression diode is a protection device across the contactor coil. Energizing the contactor coil creates a magnetic field that forces the solenoid arm to engage the contacts. When the contactor is turned off, the magnetic field collapses causing a back “voltage spike” that can damage the controller.

Voltage Rating (VAC) in electronic components refers to the maximum voltage that a component can safely handle without risk of failure or breakdown. It is typically expressed in volts, specifically in alternating current (AC) applications. Exceeding this voltage can lead to insulation breakdown, damage, or catastrophic failure of the component. Manufacturers specify this rating to ensure safe and reliable operation within the intended application.

The parameter "Product Length (mm)" in electronic components refers to the physical length of the component, typically measured in millimeters. This measurement is important for determining the size and dimensions of the component, which is crucial for fitting it into a circuit board or enclosure. It helps in ensuring proper alignment and spacing within the overall design of the electronic system. Manufacturers provide this specification to assist engineers and designers in selecting components that will fit and function correctly within their intended application.

Product Height (mm) in electronic components refers to the measurement of the component's vertical dimension. It indicates how tall the component is when installed in a circuit or system. This parameter is crucial for determining compatibility with enclosures, ensuring adequate space for components on printed circuit boards, and facilitating proper airflow and cooling in electronic designs.
