Through Hole Resistors

Through hole resistors are a type of electronic components used to control the flow of electricity in an electrical circuit. They are constructed of a cylindrical ceramic body and a metal end cap that houses the resistance element material. The lead-wires are attached to the end cap and the resistor is then mounted to a printed circuit board using soldering. The resistance value of the part is marked on the end cap, usually in ohms, kilo-ohms, or megaohms.

MFP55-49R9B1 Application Field and Working Principle

The MFP55-49R9B1 is a through-hole resistor designed for high performance applications. The device is a high power, thin film resistor that combines high reliability with low noise, long life, low temperature coefficient and high power rating. The resistor is formed by a ceramic body and a metal end cap that contains the resistance film. It is rated at 49 ohms and its power rating is up to 55W at 25°C.

The main application field of the MFP55-49R9B1 is in power supplies, amplifiers, and other high performance circuits requiring high current and low noise. The working principle of the device is based on the fact that the resistance element material, when heated up, threatens to rip apart the insulation layer and increase the current flow through the resistor, resulting in increased power and temperature rise. To prevent this, the resistor\'s power rating must be respected and the working temperature range must adhere to manufacturer’s specifications.

The MFP55-49R9B1 is well-suited for automotive, communication, computer, and industrial applications. The resistor measures 6.5 mm in diameter and 6.3 mm in length and is shipped in packable boxes of 10, 100, and 1000 units. It has a RoHS-compliant lead-free construction with a lead-free solder finish for maximum electrical performance and reliability.

Additional features include high surge current capability, low thermal EMF, and capacitance suppression. The device can provide reliable and stable performance even under harsh operational conditions. It offers a wide operational temperature range of -40°C to +125°C and can withstand brief exposure to temperatures up to +150°C.

The MFP55-49R9B1 is an excellent choice for resistance applications in power supplies, as it is able to reduce noise and provide reliable performance. It is a high power, high reliability thin film resistor with long life, low temperature coefficient, and excellent surge current capability. It is an ideal choice for high performance applications that require low noise and stability under stringent operating conditions.
