Polymeric PTC Resettable Fuse 6V 1 A Ih Surface Mount 0603 (1608 Metric), Concave polyfuse 1A 0603 The 0603L100SLYR is a surface-mount resettable fuse (PPTC – Polymeric Positive Temperature Coefficient) designed to provide overcurrent protection in low-voltage electronic circuits. When excessive current flows, the device increases its resistance sharply, limiting current and protecting downstream components. Once the fault condition is removed and power is cycled or reduced, the fuse resets automatically. This component is widely used in compact electronic devices due to its small 0603 footprint, making it suitable for space-constrained PCB designs. Key Features Resettable overcurrent protection device Compact 0603 surface-mount package Fast response to fault conditions Automatic reset after fault removal RoHS compliant and lead-free construction Low resistance in normal operation Stable performance over multiple trip cycles Electrical Characteristics Hold current: 1.0 A Trip current: approximately 2.0 A Maximum voltage rating: 6 V Maximum current rating: 40 A (short duration fault current) Initial resistance: low resistance typical 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 current and ambient temperature Self-heating mechanism triggers resistance increase Mechanical Characteristics Package type: 0603 (1608 metric) Mounting type: surface mount (SMD) Body material: polymer-based PTC Terminal finish: solderable metal electrodes compatible with reflow soldering Applications USB ports and power lines Battery-powered devices Consumer electronics Portable devices Embedded systems and IoT hardware Power supply protection circuits Compliance and Standards RoHS compliant Halogen-free (typical for series) Meets industry standards for resettable fuses #commonpartslibrary #circuitprotection #ptc #fuse

Polymeric PTC Resettable Fuse 16V 3 A Ih Through Hole Radial, Disc # Engineering Specification ## Product Name RGEF300 ## General Description RGEF300 is a resettable polymeric positive temperature coefficient protection device designed to safeguard electronic circuits against overcurrent and fault conditions. The component is intended for use in power distribution systems, low-voltage DC rails, and electronic assemblies where temporary overload protection and automatic recovery are required. The device operates by increasing its internal resistance when subjected to excessive current or elevated temperature conditions, thereby limiting fault current and protecting downstream circuitry. Once the fault condition is removed and the device cools, it returns to a low-resistance state, allowing normal operation to resume without the need for manual replacement. RGEF300 is widely used in industrial electronics, consumer devices, automotive subsystems, communication equipment, and embedded systems where reliable overcurrent protection and system uptime are critical. Its radial-leaded configuration supports straightforward integration into through-hole PCB designs and legacy circuit architectures. The design emphasizes consistent trip behavior, stable reset characteristics, and long-term reliability under repeated fault conditions. It is suitable for applications requiring self-resetting protection elements that reduce maintenance requirements and improve system resilience. ## Functional Requirements ### Overcurrent Protection The device shall limit current flow during fault conditions by increasing resistance when exposed to excessive current. ### Automatic Reset The device shall return to a low-resistance state once normal operating conditions are restored and thermal conditions stabilize. ### Fault Isolation The device shall provide temporary isolation of downstream circuitry during overcurrent events. ### System Protection Support The component shall support use in electronic systems requiring reusable protection elements for power input and distribution paths. ## Electrical Requirements ### Normal Operation The device shall maintain low resistance under normal operating current conditions to minimize power loss. ### Trip Behavior The device shall transition to a high-resistance state when subjected to fault-level current conditions. ### Thermal Response The device shall respond to both electrical current and self-heating effects to initiate protective action. ### Recovery Characteristics The device shall restore normal conduction after fault clearance and thermal recovery. ## Mechanical Requirements ### Radial Leaded Construction The device shall be provided in a through-hole radial package suitable for PCB mounting. ### Structural Integrity The component shall maintain mechanical stability during soldering, handling, and operational thermal cycling. ### Board Integration The device shall be compatible with standard PCB layouts used in power protection circuits. ## Environmental Requirements ### Operating Conditions The device shall operate reliably in industrial, consumer, and embedded electronic environments. ### Thermal Performance The device shall tolerate repeated heating and cooling cycles associated with fault events. ### Storage and Handling The component shall maintain electrical and mechanical integrity during storage and transportation. ## Quality Requirements ### Reliability The device shall support repeated fault recovery cycles without permanent degradation under specified operating conditions. ### Verification Electrical trip behavior, resistance recovery, and thermal response shall be validated through standard qualification testing. ### Compliance The product shall conform to applicable safety and electronic component standards for resettable overcurrent protection devices. ## Documentation Requirements Technical documentation shall include application guidelines, derating considerations, PCB layout recommendations, fault behavior characteristics, and integration practices for circuit protection design. ## Classification Tags #RGEF300 #PTCResettableFuse #Polyfuse #PPTC #OvercurrentProtection #CircuitProtection #ResettableFuse #PowerProtection #FaultProtection #ThermalProtection #ElectronicComponents #ElectricalEngineering #PCBDesign #PowerDistribution #IndustrialElectronics #AutomotiveElectronics #EmbeddedSystems #CommonPartsLibrary #ComponentLibrary #EngineeringSpecification #ReliabilityEngineering #SelfResettingProtection

Polymeric PTC Resettable Fuse 6V 3 A Ih Surface Mount 1812 (4532 Metric), Concave The 1812L300MR is a surface-mount resettable fuse (PPTC – Polymer Positive Temperature Coefficient) designed to provide overcurrent protection in electronic circuits.
