Chassis Mount Resistors

Chassis Mount Resistors are an important component of many electrical and electronic products. They are used in applications such as power supplies, circuit protection, over-voltage protection, and EMI suppression. The Chassis Mount Resistors are designed to perform in extreme temperatures and vibrations, and be stockable in circuit boards and chassis. The AHA50AFB-0R28 is a type of chassis mount resistor is often used in applications where high vibration is encountered.

AHA50AFB-0R28 Application Field and Working Principle

The AHA50AFB-0R28 chassis mount resistor is a resistor with a 50 ohm resistance value, available in a through-hole (TH), or surface mount (SMT) version. It is widely used for high vibration applications such as military, aerospace, and motorsport. The resistor is made of ceramic and molybdenum, with a low thermal coefficient and excellent temperature stability. Additionally, it features a wide operating temperature range, from -55 to +150oC.

The AHA50AFB-0R28 features a flat flanged top section, which allows the resistor to be mounted firmly to a chassis or board. The gap between the resistor and the chassis is maintained by a flat, stamped or machined feature. The solder tabs and bumpers on every side of the chassis mount resistor perform a specific electrical and mechanical coaxial-like function, which aids in additional vibration resistance.

The AHA50AFB-0R28 chassis mount resistor is designed with a dual mount architecture, which helps maintain optimal contact between the resistor and the chassis. The resistor is designed to remain stable even in high vibration or shock conditions, and to ensure that the electrical contact between the resistor and the chassis is not impacted by mechanical stress. The resistor is also designed to resist high temperatures, and to ensure that the resistance value remains the same over the entire temperature range.

The AHA50AFB-0R28 is RoHS compliant, making it suitable for applications where high vibration is encountered. It is also military and NASA qualified, making it a versatile component for many applications. The resistor is designed for a wide range of temperatures, from -55oC to +150oC, and is certified to meet the vibration and shock requirements of military level C and a rating of 1,500 g.

The AHA50AFB-0R28 chassis mount resistor is a highly reliable and versatile component, and is often used in applications where high vibration is encountered. Its dual mount architecture ensures a secure electrical contact even in extreme temperatures and vibrations, and makes it suitable for use in tough environments. The resistor is RoHS compliant, military and NASA qualified, and certified to meet the vibration and shock requirements of military level C and a rating of 1,500 g.
