SMD050F-2
Polymeric PTC Resettable Fuse 60V 500 mA Ih Surface Mount 2-SMD 500mA resettable fuse pptc The SMD050F-2 is a surface-mount resettable fuse (PPTC – Polymer Positive Temperature Coefficient) designed to provide overcurrent protection in low-voltage electronic circuits. It operates by increasing its resistance significantly when excessive current flows, thereby limiting current and protecting downstream components. Once the fault condition is removed and the device cools, it automatically resets to its low-resistance state, enabling normal operation without replacement. This component is commonly used in power supply lines, USB ports, battery-powered devices, and general electronic protection applications where space-saving and reliability are important. Key Features Resettable overcurrent protection (self-recovering) Surface-mount package for compact PCB layouts Low resistance in normal operation Fast response to fault conditions Automatic reset after fault removal RoHS compliant and lead-free Electrical Characteristics Hold current: 0.5 A Trip current: 1.0 A (typical) Maximum voltage: 60 V Maximum current: 40 A (fault current rating) Initial resistance: low resistance range suitable for minimal voltage drop Resistance after trip: significantly increased to limit current Thermal Characteristics Operating temperature range: -40°C to +85°C Trip time dependent on applied current and ambient temperature Reset time dependent on cooling conditions Mechanical Characteristics Package type: Surface-mount (SMD) Compact footprint suitable for dense PCB layouts Compatible with standard reflow soldering processes Applications USB and peripheral port protection Power supply and DC line protection Battery pack protection Consumer electronics Industrial control circuits Compliance and Standards RoHS compliant Halogen-free (depending on manufacturer variant) Meets industry standards for resettable fuses #commonpartslibrary #circuitprotection #ptc #fuse... show more610 Uses

0603L050YR
Polymeric PTC Resettable Fuse 6V 500 mA Ih Surface Mount 0603 (1608 Metric), Concave polyfuse 500mA 0603 The 0603L050YR is a surface-mount resettable fuse based on polymeric positive temperature coefficient technology, designed to provide overcurrent protection in compact electronic circuits. Under normal operating conditions, the device exhibits low resistance and allows current to pass with minimal power loss. When exposed to an overcurrent condition, the device transitions to a high-resistance state, effectively limiting the current and protecting downstream components. Once the fault condition is removed and power is cycled or the device cools, the fuse automatically resets to its original low-resistance state. This component is optimized for space-constrained applications requiring reliable, resettable protection, such as portable electronics, battery-powered systems, and low-voltage signal lines. Its small form factor enables integration into dense PCB layouts while maintaining compliance with industry safety standards for overcurrent protection. Package and Mounting: Surface-mount device in standard 0603 footprint, compatible with automated assembly processes including reflow soldering. Electrical Characteristics: The device is designed to maintain normal operation at a defined hold current level and transition to a protective state when the current exceeds its trip threshold. It operates within low-voltage circuits and provides fast response to fault conditions while minimizing nuisance tripping under typical load variations. Functional Behavior: The fuse operates by increasing resistance sharply in response to thermal energy generated by excess current. This behavior reduces current flow and limits fault energy. After removal of the overcurrent condition, the device gradually returns to its conductive state, enabling repeated use without replacement. Applications: Suitable for use in power lines, battery packs, USB interfaces, consumer electronics, and other low-voltage systems where resettable overcurrent protection is required. Compliance and Reliability: Designed to meet relevant safety and environmental standards for electronic components, ensuring stable performance across specified operating conditions and long-term reliability in field applications. #commonpartslibrary #fuse #Circuit-Protection #PTC #ptc #polymeric... show more189 Uses
