Chassis Mount Resistors
A chassis mount resistor is a type of resistor that is designed to be physically mounted on a chassis, or to be used as an external component of a particular device or appliance. Chassis mount resistors are commonly used in power supplies, audio amplifiers, and other electrical devices.
AHA50AFB-0R14 Application Field and Working Principle
The AHA50AFB-0R14 is a precision-type two-terminal, chassis mount resistor, specifically designed to be used in special applications. The AHA50AFB-0R14’s resistance value is extremely stable over time, making it ideal for applications where precision is a requirement. This freedom from drift makes the AHA50AFB-0R14 an ideal resistor for applications that require long-term accuracy in their measurements.
The AHA50AFB-0R14 achieves its precision and stability through its unique construction. It is made from a combination of two resistive elements. The first element consists of an aluminum foil element, which is responsible for its extremely low temperature coefficient. The second element features a standard wirewound element, which provides the resistance value. The combination of these two elements creates the highly stable and precise resistor value.
The AHA50AFB-0R14 also features a powerful heat dissipation system, using a combination of an epoxy body and a thermal conductive material. The epoxy body absorbs heat and dissipates it through the thermal conductive material, ensuring that the resistor stays within optimal temperature parameters. This feature gives the resistor superior reliability, making it ideal for long-term accuracy in measurements.
In terms of physical construction, the AHA50AFB-0R14 uses an industrial-grade steel surface mount that is extremely resistant to corrosion. It is also designed to balance the resistance to provide optimal heat dissipation with minimal increase in temperature. This specific design also improves resonant properties and ensures accuracy over a wide range of frequencies. The design also ensures that vibration is minimized which decreases measurement drifts.
Finally, the AHA50AFB-0R14 is specifically designed for use in high power applications, as it can handle voltage values of up to 36V. This allows for higher current applications without sacrificing accuracy or reliability. It also features a low internal inductance, ensuring that the impressive power rating is achieved.
In conclusion, the AHA50AFB-0R14 is an excellent, rugged, and reliable chassis mount resistor. Its unique design and construction give it unbeatable accuracy and utmost stability. Its resistance to corrosion, high power rating, low internal inductance, and superior heat dissipation make it an ideal choice for applications where precision is required. Furthermore, its inexpensive price makes it an incredibly cost-effective choice.
