FUZETEC, as a leading manufacturer specializing in PPTC (Polymer Positive Temperature Coefficient) self-healing fuses, offers a variety of fuse products to meet the circuit protection needs of different scenarios. The following are the classification and characteristics of its main categories:
Surface Mount (SMD) Series
FSMD series: designed specifically for high-density circuit boards, using surface mount technology, with sizes including 1206, 1210, 1812, 2920, etc., maintaining a current range of 50mA to 3A, and a maximum operating voltage of 6V to 60V. Suitable for scenarios such as computer motherboards, USB interfaces, lithium batteries, etc., it complies with UL1434 standards.
FRA series: For example, FRA050120F, with a working voltage of 120V and a current range of 0.50A, has fast action and low resistance characteristics, suitable for low-voltage DC or AC power protection.
Radial lead plug-in series
FRG series: High current carrying capacity, working current of 2.50A~14.00A, rated voltage of 16VDC, suitable for high-power equipment such as power supplies and motors.
FHT series: Designed for a wide temperature range (40 ℃ to 125 ℃), with a working current of 0.50A~15.00A and optional voltage of 16VDC or 30VDC, suitable for industrial equipment in high-temperature environments.
FRU series: Operating current 0.90A~9.00A, rated voltage 30VDC, self recovery function suitable for frequent protection scenarios such as automotive electronics and USB devices.
High voltage dedicated series
FRHV series: For telecommunications and network equipment, the working current is 0.08A~0.40A, and the rated voltage can be selected from 60VDC, 100VDC, and 250VDC, with a maximum interruption voltage of 600VAC.
FRVL series: suitable for line voltage protection (120VAC/DC), working current 0.10A~3.75A, commonly used in household appliances and industrial equipment.
Special Application Series
Thin film fuse: specially designed for battery packaging, with low heat dissipation characteristics, suitable for portable electronic products.
Customized specifications for customers, such as circular plates, to meet special packaging or performance requirements.
Core features and advantages
Self recovery function: No need for replacement, reducing maintenance costs.
Low resistance and fast response: reduce power loss and improve circuit efficiency.
Diversified packaging: covering various forms such as plug-in, patch, and thin film.
International certification: By obtaining safety certifications such as UL, CUL, T Ü V, etc., we ensure reliability.
Selection suggestions
Current and voltage matching: The model should be selected based on the maximum operating current and voltage of the circuit (such as FRG for high current and FRHV for high voltage).
Environmental adaptability: FHT series is preferred for high temperature scenarios, and surface mount FSMD series is chosen for compact spaces.
Application scenarios: FRA or FSMD are recommended for consumer electronics, while FRU series is suitable for industrial or automotive electronics.
