Chassis Mount Resistors are widely used to modify electrical signals or dissipate power in industrial and consumer electronic circuits. The AHA500FB-549R is a subcategory of Chassis Mount Resistors that is designed to provide precision resistance values for applications that require incredibly low resistance values. This resistance component can be used to provide a variety of solutions for circuit design requiring low resistance values from 10 ohms to as much as 59.9 ohms.

The AHA500FB-549R is designed with a moulded polymer case and features a high precision ceramic insert to achieve a low resistance output. This resistance component is resistant to surge voltages and can operate at temperatures ranging from -55°C to +130°C to provide an incredibly reliable low resistance solution even in very demanding environmental conditions. The overall size of this component measures 64mm (L) x 30mm (W) x 14mm (H).

In terms of performance, the AHA500FB-549R is capable of providing up to a 5W dissipation rate with a tolerance value of +2/-2%. It also includes a lever tilt style terminal and a one-sided press-in contact for secure mounting. This proprietary design ensures that the contact is properly installed into the mounting system in order to provide an accurate resistance connection.

The AHA500FB-549R is primarily designed for use in modern industrial applications such as automotive applications, telecommunications, data processing, and power supplies. This component can also be used for audio signal conditioning, EMI/RFI suppression, and power distribution. Its low resistance value is particularly beneficial in applications requiring the precise resistance output such as audio signal conditioning and power distribution where inaccuracies in the resistance value can lead to undesired responses.

The AHA500FB-549R is designed according to the JEDEC standards, and is soundly engineered in order to handle extreme loads without causing any distortion or incorrect output. This resistance component operates with an overload voltage that does not exceed specified values, further enhancing its reliability and providing consistent performance throughout its entire life cycle. It also features a flame retardant rating of UL 94V-0, making it suitable for applications involving fire safety.

In terms of its working principle, the AHA500FB-549R utilizes a combination of materials and components to control the flow of electricity within a circuit and maintain a low resistance output. This is achieved through the combination of a resistive insert, a moulded case, and contact terminals. The moulded case is constructed with a fire retardant material that radiates heat evenly, while the insert is designed to offer high-precision resistance. The contact terminals are connected to the moulded case with a one-sided press-in mechanism.

With its combination of reliable performance, fire-retardant rating, and precision resistance values, the AHA500FB-549R is an ideal option for applications involving low resistance values such as audio signal conditioning and wireless power transfer. It is also capable of operating in extreme temperatures and conditions, ensuring a reliable connection even in demanding environments.
