MBB02070C3303DC100

Through Hole Resistors are typically large, cylindrical components with wire leads that pass through a mounting hole in a printed circuit board (PCB) and are soldered to the board. Specifically, the MBB02070C3303DC100 is a thick film resistor with a 22-60 μm thick Ni-Cr film layer. It offers a power rating of 3 Watts and a resistance range of 0.01Ω - 1MΩ. The resistance value and tolerance can be tailored to the user’s specific design requirements.

Application Field:

The MBB02070C3303DC100 through hole resistor is widely used across multiple industries. Some of the common applications include industrial control systems, medical equipment, computers, consumer electronics, lighting systems, and automotive systems. It is especially useful in high-reliability industries as it offers high stability and low noise.

Working Principle:

The MBB02070C3303DC100 through hole resistor works on the principle of ohmic resistors. In ohmic resistors, the resistance is essentially a measure of the material’s ability to conduct electricity. The resistor is usually made of a thin film of metal oxide or nitride that is deposited on a ceramic substrate. When current passes through the resistor, it encounters electrical resistance from the material; this resistance causes the current to decrease as it travels across the resistor. This, in turn, limits the amount of current that can flow through the circuit.

The resistance value of the resistor is typically determined by its size and geometry. The longer the resistor, the higher its resistance value will be. This is because more of the resistive material will be present, thus increasing the overall resistance of the part. Additionally, the thicker the film material, the higher the resistance value will be. This is because the thicker film has more resistive material, which creates a higher resistance.

The resistance value of the MBB02070C3303DC100 resistor can be tailored to meet a user’s specific design requirements. The resistor is usually manufactured using a thick film process, which allows for custom-tailored resistor values. This process involves depositing a thick film of Ni-Cr onto a ceramic substrate, which is then screen-printed in the desired shape. The resistor is then fired, which hardens the material and sets the resistance value. Additionally, the resistor can be coated with a protective material to increase its lifespan.
