As the core component of circuit protection, TAI fuses have a product line covering various types and specifications, mainly classified according to their melting characteristics, structural forms, and applicable scenarios. The following is a detailed summary of its core categories:
1、 Classified by circuit breaker characteristics
Quick melting fuse
Features: Fast response speed, suitable for circuits that are sensitive to current and need to quickly cut off fault currents. For example, in semiconductor protection or precision electronic equipment, it can effectively avoid device damage caused by transient overcurrent.
Representative series:
CF series: such as CF06V2T3R15 (0603 package, rated current 3.15A, breaking capacity 50A), suitable for computer peripherals, digital cameras, etc.
CP series: such as CP06V5TR50 (0603 package, rated voltage 50V), using thin film manufacturing process, low internal resistance, commonly used in LCD displays, portable devices, etc.
Slow melting type (delay type) fuse
Features: Can withstand short-term pulse current surges (such as startup surges), suitable for scenarios with instantaneous current fluctuations, such as power modules or motor drive circuits.
Representative series:
CFS series: With a long melting time (such as several seconds at 250% rated current), it is suitable for devices such as battery packs and inverters that require surge resistance.
2、 Classified by structural form
Surface mounted disposable fuse
Features: Small size (0402/0603/1206 package), suitable for high-density PCB design, and needs to be replaced after melting.
Typical products:
CF/CFS series: covering a voltage range of 24V~63V, with a current of 0.5A~7A and a breaking capacity of up to 50A, used for consumer electronics and industrial control.
CP series: Provides voltage options of 32V~125V, current range of 0.5A~4A, and optimized power consumption with low internal resistance characteristics.
Self healing fuse (PPTC)
Features: Automatic reset after overcurrent, no need for replacement, suitable for scenarios that require repeated protection (such as USB ports, battery management).
Representative series:
TRF series: such as TRF12200V06EF (1206 package, maximum voltage 32V), with low internal resistance and high breaking capacity, widely used in mobile phones, chargers, etc.
3、 Classified by application scenario
Consumer Electronics and Portable Devices
Applicable products: CP series, CF series, meet the demand for miniaturization, such as digital cameras, game consoles, etc.
Industrial and Automotive Electronics
Applicable products: CFS series with high breaking capacity (such as 63V/7A), used for high reliability scenarios such as inverters and motor control.
High voltage/high current scenarios
Applicable products: 125V high voltage models in the CP series, suitable for power modules and electrical equipment.
4、 Key parameters and selection points
Rated voltage and current: need to be higher than the maximum operating value of the circuit, for example, the CP series provides 32V~125V options.
Breaking capacity: The CFS series can reach 20kA (semiconductor protection level), while surface mount models such as CF06V2T3R15 have 50A
Temperature impact: In high-temperature environments, it is necessary to choose models with higher rated currents (such as increasing by 20% or 25%).
Package size: 0402 (1.0 × 0.5mm), 0603 (1.6 × 0.8mm), etc., suitable for different space requirements.
Dayi fuses cover the full range of needs from consumer electronics to industrial systems through a diversified product line. When selecting, it is necessary to comprehensively consider the circuit characteristics (such as current fluctuations, space limitations) and environmental factors (such as temperature), and match them with the specific model's melting curve and breaking capacity.
