YC248-FR-0748R7L

As technology advances and becomes more advanced, it\'s critical to understand the various components of various products. Resistor networks, arrays are part of that complex technology, and the YC248-FR-0748R7L component is an important one. Let\'s explore the application field and working principle of the YC248-FR-0748R7L.

Application Field

The YC248-FR-0748R7L is a Multi-Layer Thick Film Resistor Network broadly used in different kinds of electronic products. Mainly, it is used in switching power supplies, telecommunication products, LCD modules, medical devices and consumer electronics.When it comes to switching power supplies, its application is twofold. First, it helps reduce the dimensions of the system by combining the film resistors within the component. Second, it helps tailor the desired input impedance characteristics of the system.In Telecommunications products, it is usually used in applications like impedance matching, signal filtering and noise control.In LCD modules, it is used in video signal buffering, display driving or LCD tablet application. Medical devices usually call for resistors networks for impedance matching, signal filtering and to make sure the device works at the desired operating environment and noise conditions.Finally, the YC248-FR-0748R7L is also important in many consumer electronic products, like DVD players, digital cameras and multimedia products.

Working Principle

The YC248-FR-0748R7L is a Multi-Layer Thick Film Resistor Network with four resistors, three of them in parallel and the fourth one in series. The Thick Film Resistor is composed of a ceramic substrate, a well patterned layer of conductive paste and a protective layer. The substrate is usually made of the same ceramic material that’s used in regular Multi-layer Ceramic Capacitors. The thin paste layer is made of a conductive material, often a mixture of silver, gold, nickel, palladium or alloys of those elements. The protective layer usually contains glass and is preheated onto the substrate and paste layers, to ensure that the component connects properly.The YC248-FR-0748R7L is notable for its low specific resistance, and its ability to have custom tailored parts which are non-inductively wound. This makes the component ideal for use in circuits where resistance values must be tailored or matched. The component also eliminates the need for traditional fusible resistors in such circuits.The component also offers excellent stability, and the device is highly insulated and reliable in operation. It has very small parasitic capacitances and works in a wide range of temperature and high-frequency applications.

Conclusion

The YC248-FR-0748R7L is a thick film resistor network, that is widely used for its excellent stability and ability to operate in a wide range of temperatures. It is also important in its application field, to reduce the dimension of systems, tailor the desired input impedance characteristics, and likely used in telecommunications products, LCD modules and consumer electronics.
