Chassis mount resistors encompass a range of resistors used in electronic circuits, where the resistor needs to be mounted inside the chassis of the device, and where space is limited. Relevant examples include automotive and other motion control systems, telecommunications and data acquisition systems and applications requiring quick response times such as alarm systems.

The AHA25AFB-19R6 is a premium quality chassis mount resistor designed with superior immunity to electrostatic discharges (ESD) and extreme environmental conditions, making them perfect for those applications requiring the highest reliability. The AHA25AFB-19R6 is an axial leaded device and is available in a wide range of resistance values in both ceramic and metal film types.

The AHA25AFB-19R6 has a wide range of possible applications, including a large variety of filters, attenuators, couplers, circuits needing resistance temperature compensation, surge protection in bridge circuits, emergency braking systems, robot controllers, controlling motors, switching regulators, and as V/I sources for transistor matrices.

The AHA25AFB-19R6 provides excellent EMC/EMI shielding (low Z) and compatibility performance, making them suitable for use in automotive applications present in cars. Its optimized wedge design prevents above-mentioned interferences from entering the resistor, thus providing a high EMC/EMI shielding capability with minimal influence on other parts of the circuit.

The AHA25AFB-19R6 is composed of a three-layer epoxy and polyurethane resin, and the encapsulating material has excellent flame retardance, insulating properties, and high-temperature resistance. This allows them to work strongly in applications with high temperature, moisture, vibration, and O2 concentrations.

The AHA25AFB-19R6 employs thermoplastic constructed epoxy resin, over-molded onto a high-temperature ceramic body. This ensures excellent temperature and moisture capability for -40 to 85 degrees Celsius and 0 to 95% humidity. This makes them ideal for use in harsh conditions such as automotive or outdoor applications.

The AHA25AFB-19R6 operates on a simple principle - current flowing through the resistor causes a voltage drop related to the resistance. Thus, a higher resistance value leads to a larger voltage drop. This voltage drop compensates for any additional voltage present in the circuit, enabling the desired level of current to flow.

It also incorporates a non-linear behaviour for higher currents, providing an extra degree of accuracy when compared to a standard linear resistor. Therefore, they are ideal for applications requiring highly precise resistor values such as automation controls and analog systems.

The AHA25AFB-19R6 is also highly reliable due to its robust construction and superior temperature stability. The resistors are built to withstand shocks, vibration and temperature variation, while also providing stable characteristics over a wide temperature range of -40 to 85 degrees Celsius. The superior stability ensures that the AHA25AFB-19R6 can be used reliably in applications that require precise and consistent values of resistance.

The AHA25AFB-19R6 is specifically designed to be a low-profile, robust and reliable chassis-mount resistor, suitable for use in a wide range of applications. It is highly resistant to temperature and humidity, and has superior shielding properties for reducing EMC/EMI interferences. Furthermore, it also has excellent thermoplastic construction and non-linear accuracy for even better control in more sensitive applications.
