SMD0603B020TF

Ptc Resettable Fuses Overview

The YAGEO SMD0603B020TF is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse designed for circuit protection. It operates with a maximum voltage of 6 VDC and maintains a hold current of 200 mA, while tripping at 400 mA. The component features a compact 0603 package measuring 1.6 mm in length, 0.8 mm in width, and 0.45 mm in height. It supports a maximum fault current of 100 A and dissipates up to 100 mW of power. The device functions reliably within an operating temperature range of -40°C to +85°C.

Ptc Resettable Fuses Procurement Notes

Verify the specific manufacturer part number against official YAGEO documentation to confirm electrical ratings and package dimensions. Ensure that the selected component meets the required voltage and current specifications for the target application. Cross-reference datasheets for thermal derating curves and trip time characteristics to validate suitability for the intended circuit design.

Ptc Resettable Fuses Selection Notes

Select this component based on the system's maximum operating voltage and steady-state current requirements. Confirm that the hold current exceeds the normal operating current while the trip current remains below the threshold where damage could occur. Evaluate the physical space constraints to ensure the 0603 footprint fits the PCB layout. Consider the ambient temperature range to verify that thermal derating does not compromise protection reliability.

Ptc Resettable Fuses Part Context

This component belongs to the YAGEO SMD series of resettable fuses, which are engineered for surface-mount assembly. The series provides a compact alternative to traditional fusible links, offering reusable protection in small form factors. These devices are commonly integrated into modern electronics where space efficiency and automatic recovery from fault conditions are critical design requirements.

Ptc Resettable Fuses Replacement Considerations

Compatible substitutes include other 0603 PPTC fuses with matching 6VDC voltage rating and 200mA hold current. Verify that alternative parts maintain similar trip current levels and physical dimensions to ensure board compatibility.
