When a 2.8mm Faston is too small for the current or too flimsy for the application, the next standard size is 4.8mm (0.187 inch). The QUADRIOS 1908C181 provides 25 male plugs, 25 female receptacles, and 50 insulating sleeves for 0.5-1.0 mm² wire. The wider tab distributes current over a larger contact area, reducing resistance and heat generation.

FASTON 4.8mm Series Applications

The 4.8mm width is common in power supply connections, HVAC compressor terminals, battery chargers, and industrial control cabinets where higher amperage (typically 15-20A) passes through the connection. The 0.5mm thickness is the standard for this size – sufficient for the wire gauge range provided. For even higher currents, consider moving to 6.3mm (.250) series terminals.

Current Capacity Considerations

While the 4.8mm tab size can handle currents up to approximately 20A, the actual capacity is limited by the wire gauge (0.5-1.0 mm² is rated for roughly 10-15A depending on insulation type). For full 20A operation, larger gauge wire (1.5-2.5 mm²) should be used with the appropriate terminal. This kit is optimized for the supplied wire range, making it ideal for appliance repair where OEM wiring is often 0.75-1.0 mm².

Tip: For high-vibration applications (automotive, marine), consider applying a small amount of dielectric grease inside the receptacle before mating to prevent corrosion and maintain low contact resistance over time.

The set includes transparent insulating sleeves that slip over the crimped terminal for protection against accidental shorts. Use these when repairing a furnace blower motor, replacing a power supply in a vending machine, or building a battery backup system. Each set contains 25 plugs, 25 receptacles, and 50 insulating sleeves – enough for 25 complete connector pairs.
