ST2-DC12V Power Relays, Over 2 Amps by Panasonic

Contact resistance measures the electrical resistance at the interface between mating contacts. Lower values indicate better conductivity and less heat generation. Compare this parameter across connectors, relays, and switches to ensure reliable signal integrity and power transfer. Always verify against the datasheet for your specific application.

Identifies the company that designed and produced the component. Buyers often filter by manufacturer to ensure brand reliability, quality standards, and supply chain consistency. Verify the manufacturer against the datasheet and official packaging to avoid counterfeit parts.

Indicates the specific product subcategories or classifications within the broader component family. Helps narrow down search results and identify the exact type of component needed for your design. Review the subcategory to ensure compatibility with your application.

Lists the product categories or classifications assigned to this component, such as connectors, capacitors, or modules. This helps in filtering and comparing similar parts. Review the categories to ensure the component fits your application and to find alternative parts in the same class.

Length of the termination or lead on components like resistors, capacitors, or connectors, affecting solder joint reliability and mechanical fit. This dimension is crucial for through-hole and surface-mount parts. Ensure the termination length matches your PCB hole depth or pad size. Verify the exact length in the datasheet for proper assembly.

Specifies the highest alternating current voltage the component can withstand continuously without damage. Compare this rating with your circuit's operating voltage and transients. Always verify against the datasheet for derating factors and safety margins.

Power consumed by the relay coil when energized at its nominal voltage. Compare this value to ensure the coil's heat dissipation is within the relay's thermal limits. Verify against the datasheet for your specific coil voltage and operating conditions.

This is the maximum voltage that can be applied between the relay coil and its contacts without causing insulation breakdown. It ensures safe isolation between control and switching circuits. Verify this rating against the datasheet for your application's voltage requirements.

Specifies the maximum voltage that the contact can safely switch during operation. Essential for ensuring the component matches your circuit's voltage levels. Always check the datasheet for derating factors and load type.

Overall dimensions of the component, including length, width, and height. Essential for PCB layout and enclosure design. Confirm these measurements against the datasheet to ensure proper fit and clearance in your assembly.

Indicates the product series or family, grouping components with similar design and specifications. Helps identify compatible parts and compare within a product line. Verify the series against the datasheet to ensure correct application.

Specifies the physical weight of the electronic component, important for logistics, shipping cost, and mechanical design. Verify the exact weight in the datasheet or packaging information, as it may vary with packaging type and quantity.

Indicates the industry specification or standard the component complies with, such as IEC, MIL, or JEDEC. Buyers use this to ensure regulatory and quality compliance. Verify the exact standard and revision against the datasheet before design-in.

Height of the switch body from the mounting surface to the top, excluding the actuator. Critical for clearance in enclosures and for PCB assembly. Verify it matches your mechanical design constraints and soldering process requirements.

Specifies the physical size of the component body, either its length for rectangular parts or diameter for cylindrical ones. This dimension is critical for PCB layout and mechanical fit. Verify against the datasheet to ensure clearance and proper mounting in your enclosure or assembly.

Measure the widest dimension of the component body, excluding leads and terminals. This attribute helps determine PCB footprint compatibility and mechanical fit. Verify against the datasheet drawing for accurate placement and clearance in your assembly.

The unique part number assigned by the original component manufacturer. Use this to cross-reference datasheets, verify specifications, and ensure the exact component matches your design requirements. Always confirm the number against the manufacturer's official documentation.

Typical power consumption of the component under normal operating conditions. This is important for power budget calculations and thermal management. Check the datasheet for maximum ratings and test conditions to ensure your design stays within safe limits.
