Chassis Mount Resistors

Chassis mount resistors are non-inductive resistors that are normally mounted to a metal chassis for cooling and secure an improved electrical connection. These resistors are generally used in applications that need a very secure mount, such as power supplies, automotive equipment, and instrumentation. The FVE030020ER700KE model in particular is a high power, high discreteness, low-profile, surface-mounted resistor. It is designed for high reverse power applications and can withstand short-term peaks of up to 30W and continuous operations of up to 20W.

Application Field

The FVE030020ER700KE model is ideally suited for applications needing high-power dissipation such as high-speed AC-to-DC conversion, AC motor drive circuits, medium power motor control, and high-speed switching regulators. It is also used in automotive applications such as electric vehicle motor controls, regenerative braking, 3-phase motor applications, short-term over-voltage protection, AC motor drives, anti-lock brake systems, and traction control systems. In addition, it is used in medical imaging, robotics, and factory automation.

Working Principle

The FVE030020ER700KE model features an advanced ceramic coating to ensure reliable and stable performance over a wide temperature range. The device uses a power resistor that employs a high-tensile-strength metal alloy which is then pre-treated and protective coated. The metal alloy offers excellent thermal dissipation and can handle high thermal energy with low thermal resistance. In addition, it delivers high-precision voltage control thanks to its very low-resistance characteristics. The pre-treated coating also protects the resistor from environmental damage.

The resistor also employs a low-inductance design to provide better thermal performance than traditional resistors. This helps to reduce thermal distortion and thermal drift for improved stability over time.

Conclusion

The FVE030020ER700KE model is a high-power, high-discreteness, low-profile, surface-mounted resistor that is ideally suited for high-power applications. It features a unique ceramic coating and a power resistor made out of a high-tensile-strength metal alloy with pre-treatment and protective coating. This allows for high thermal energy with low thermal resistance and high-precision voltage control. In addition, the resistor is designed with a low-inductance design for improved thermal performance and stability over time. All these features help make the FVE030020ER700KE model an ideal choice for applications such as AC-to-DC conversion, automotive equipment, instrumentation, and medical imaging.
