CMF5578K700FKRE through hole resistors are miniature surface mount resistors produced by Vitrohm. They may be used in applications where a robust, reliable and small package is required. The device is constructed from ceramic materials with the resistor element embedded inside the substrate.

These devices have a resistance value of 7K ohms, a tolerance of 5%, and an operating temperature range of -55°C to +125°C. They are suitable for wide range of applications in consumer electronics, automotive, military, aerospace, medical, and telecommunications. The CMF5578K700FKRE resistor is commonly used for power supplies, voltage dividers, decoupling, and attenuators.

The device is a low-value chip resistor that is commonly available in the industry standard EIA 0805 package, with dimensions of 1.6mm x 0.8mm. It has an impedance of 25 ohms, a rated power of 125mW, and a maximum pulse load of 2.9W. It is moisture resistant and is compliant with ROHS requirements.

The CMF5578K700FKRE resistor achieves its excellent performance through several features. It has a wide temperature coefficient range of -800ppm/°C to +400ppm/°C for precise control of resistance and tolerance. The resistive element is made using a multi-layer ceramic process with an internal glass and metal layer for improved stability, durability, and temperature resistance.

The resistor also offers excellent solderability and is compatible with standard soldering techniques and wave soldering. Its metallization pattern inhibits solder bridging and provides highly reliable and repeatable soldering results. Its internal geometry is optimized for low inductance to reduce ringing and noise.

The working principle behind CMF5578K700FKRE through hole resistors is that when a current passes through the resistance material, it experiences electrical resistance. This resistance creates heat energy, which is dissipated into the surrounding environment. The value of the resistance is determined by the material used and the size of the resistive element.

In the case of the CMF5578K700FKRE, the resistive element is a multi-layer ceramic substrate. This material is chosen for its efficient thermal and electrical conduction properties, as well as its general long-term stability. The resistor is constructed by depositing a uniform layer of the ceramic material into a predetermined pattern.

The pattern of the electrolytic material is designed to create a specific amount of resistance between two pins. The resistance is measured in ohms, which is expressed as the total current resistance between the two pins, when a voltage of 1V is introduced between them.

In conclusion, through hole resistors like the CMF5578K700FKRE are typically robust, reliable, and small devices, commonly used in a range of applications due to their excellent electrical characteristics and excellent construction. The device achieves its reliable performance through the use of high quality materials, precision engineering, and carefully designed internal geometry.
