Chassis Mount Resistors, encompassing a broad range of devices, are one type of circuit-defining component which helps maintain the balanced operation of circuits. The AHA500FB-196R is an axial lead, sealed rectangular package resistor developed for use in harsh, industrial environments. This type of resistor’s application fields and working principles are discussed below.

Application Field of AHA500FB-196R

The AHA500FB-196R is one of the most versatile types of chassis mount resistors used across multiple industries and applications. Most notably, they are used in auto-motives, consumer electronics, and industrial electronic applications for safety, convenience, and performance, such as:

• Automotive: In safety-critical applications such as anti-lock brakes, seatbelt monitors, and airbuilding, the AHA500FB-196R are essential in providing proper circuit protection.
• Consumer Electronics: Residential sector applications such as human-machine interfaces, motor speed controllers, and surge protection are areas where the AHA500FB-196R resistors are used.
• Industrial Electronics: In industrial applications, the AHA500FB-196R is prevalently used for supervisory control, power systems, motor controls, and measurement and monitoring.

These resistors are designed for placement that won\'t damage them or be damaged by regular wear-and-tear, such as underneath hoods, in protrusions, or on dashboards. What makes the AHA500FB-196R physically unique is its axial lead, sealed rectangular package. This package structure allows for supreme shock and vibration resistance, and is also designed to work in extreme temperatures, ranging from -55 to +125°C.

Working Principle of AHA500FB-196R

The AHA500FB-196R is an integral part of any resistive circuits, reducing the amount of current flowing through the circuit by offering an alternative pathway in which current can flow. Resistors are also used to regulate voltage, as they reduce the voltage passing through the resistor, which produces a weak electric current and helps create balance within the circuit. This balancing helps ensure the reliable operation of the circuit.

The function of AHA500FB-196R comes down to Ohm’s Law, which states that the consequent voltage (V) is equal to the current (I) multiplied by the resistance (R). Therefore, the AHA500FB-196R reduces the voltage within a circuit by offering a certain resistance. This resistance is modeled by the resistor’s resistance coefficient, withstand voltage, erroneous resistance, and more.

The resistance coefficient of the AHA500FB-196R is an important static characteristic that forms a baseline for operating parameters. Temperature Co-efficiency is another key parameter, and this coefficient represents how the resistance of the device will be affected at different temperatures. To ensure product safety and reliability, the withstand voltage rating must abide by industry standards. It describes the AC voltage (20-60 Hz) that the resistor can handle without any damage.

In addition to physical parameters, resistors also feature electrical characteristics such as leakage current, erroneous resistance, breakdown voltage, etc. Leakage current is a result of non-ideal performance, which refers to the device\'s propensity to let electric current flow at an unintended rate. The erroneous resistance is the maximum deviation for the circuit resistance at nominal rate. This value should be kept as low as reasonably possible for an optimal circuit performance.

Conclusion

The AHA500FB-196R is a chassis mount resistor, used significantly in automotive, consumer electronics, and industrial electronic applications. Its axial lead, sealed rectangular package improves shock and vibration resistance, and allows for operation in a wide temperature range. That said, the performance of AHA500FB-196R relies heavily on the values of its electrical parameters, such as leakage current, erroneous resistance, etc. This is why the AHA500FB-196R resistors are optimized for accurate and reliable performances in circuits.
