F2K Series TAM Tamura Radial Lead Porcelain Frame Thermal Cutoff Resistor Cement Resistors
Description
Cement resistors are resistors potted with cement (commonly known as refractory mud), that is, the resistance wire is wound on a non-alkaline heat-resistant porcelain piece, and the outside is protected and fixed by heat-resistant, moisture-resistant and corrosion-resistant materials. The winding resistor body is placed in a square porcelain frame and filled and sealed with special non-combustible heat-resistant cement. The outer side is mainly made of ceramic material. Cement resistors are a type of wire wound resistors, which are relatively powerful resistors that can allow relatively large currents to pass. Its function is the same as general resistance, and it can be used in products with high current. Cement resistors have the characteristics of large size, shock resistance, humidity resistance, heat resistance and good heat dissipation. They are widely used in power adapters, chargers, audio equipment, instruments, televisions, air conditioners, copiers, printers, projectors, lighting, etc. Cars, electric blankets, etc.
Features
Combination of fusible alloy thermal fuse and 2W coiled resistor
into one product
It does not contain lead (Pb) and cadmium (Cd), and complies with
RoHS, REACH
Under abnormal conditions of overload, it exerts its superior
cutting performance
In particular, a resistor element with superior performance against
inrush current is used, which is suitable for preventing inrush
current
