Thermal Cutoffs A non resettable temperature sensitive device that opens the circuit when the device reaches its rated threshold. This provides permanent overheat protection to help prevent component damage and reduce fire risk. Key benefits - Protects equipment: interrupts current when overheating is detected, preventing further heat buildup. - Permanent protection: once activated, the circuit remains open, reducing the chance of repeated overheating. - Easy integration: available with various lead configurations and mounting options to fit many assemblies. - Low maintenance: no moving parts and no recalibration needed after installation. - Reliable performance: designed for stable trip temperature and consistent operation within specified tolerances. Compatibility and form factors - Widely used in small appliances, power supplies, battery packs, and electronic assemblies that require thermal protection. - Available in multiple size and form factor options to suit different layouts and space constraints. - Lead configurations include solderable leads and other common termination methods; check the datasheet for exact options on a given model. Materials and construction - Robust metal housing with insulated leads for durable operation in typical electronic environments. - Designed to maintain performance across common operating cycles and ambient conditions within specified limits. - Construction supports secure mounting near heat sources to ensure accurate temperature sensing. Performance characteristics to consider - Temperature rating: available in a range of trip temperatures; select the rating that matches your thermal profile and safety requirements. - Action: non resettable protection that permanently interrupts current at the rated temperature. - Tolerance and stability: specified to deliver consistent operation at the designated trip point. - Current and lead options: vary by model; refer to the product datasheet for exact holding current, breaking current, lead length, and termination type. 2-3 practical use scenarios - In a household appliance such as a compact coffee maker or hair dryer, a thermal cutoff provides automatic protection against motor or heating element overheating. - In a power supply or charger, a thermal cutoff helps prevent thermal runaway by cutting power if internal temperatures rise beyond the safe limit. - In a sealed battery pack or electronic device with limited airflow, the cutoff protects cells and circuitry by opening the circuit when heat accumulates. Installation guidance - Choose the correct temperature rating and lead configuration for the application. - Mount the device so that heat sources are within the intended sensing area, following the datasheet recommendations. - Ensure proper electrical isolation and secure termination to prevent loose connections. Notes - Exact specifications such as temperature rating, current ratings, size, and lead type vary by model; consult the product datasheet for your specific part to ensure proper selection and safe integration.
