Chassis Mount Resistors are a type of resistors used to dissipate energy in applications and systems. A Chassis Mount Resistor is actually two resistors in one. It holds two flexible and insulated terminals in one electrical part. The SQBW40680RJFASTON is one such chassis mount resistor.

The SQBW40680RJFASTON is a resistor designed for maximum power dissipation at high temperatures and with lower thermal resistance than traditional resistors. It is also designed to dissipate a maximum of 0.85 W on a 25mm² heated pad and can handle a range of operating temperatures from -40° to 500°C. The resistor is housed in a hermetically sealed metal case to provide environmental protection.

The SQBW40680RJFASTON is available in five standard tolerance levels and also in custom designed packages. The resistor features a low self-resistance, low thermal resistance, high pulse flame-frost resistance and low inductance which gives it a wide range of application fields. It has been widely used in a variety of electrical and electronic equipment, from medical equipment, automotive and automotive electronics, avionics, and consumer electronics.

The SQBW40680RJFASTON offers three different basic circuit connections. One is in series-parallel connection, which means that the resistor is in series with the load and the ground. The second is in shunt connection, where the resistor is connected between the two points of the load and the ground. The third is in paralleled connection, where the resistor is in parallel to the load and the ground. The SQBW40680RJFASTON also has two temperature coefficients, a low thermal resistance coefficient and a high thermal resistance coefficient.

The working principle of the SQBW40680RJFASTON is that it behaves like a resistor and behaves as an electrical conductor that limits the current flowing through it. This principle is based on the fact that when a current is applied to the resistor, it dissipates some of its energy in the form of heat. This heat energy is then transferred to the load and the surroundings, thus maintaining the current flow within a safe range. This type of resistor works in both directions, meaning that when the current flows one way, the resistor dissipates energy; when the current reverses, the resistor dissipates the same amount of energy.

The SQBW40680RJFASTON is well-suited for applications where high power dissipation and temperature stability are required, such as in automotive and lighting applications. Its low inductance, low thermal resistance, and high pulse flame-frost resistance make it ideal for applications where low-heat dissipation and range of operational tolerances are necessary. The wide range of application fields of the SQBW40680RJFASTON makes it the ideal choice for any application where chassis mount resistors are required.
