Through Hole Resistors

The CMF5518M000FKEB is a through hole resistor, a type of resistor commonly used to regulate current in electronic circuits. Designed to perform in harsh environments, it combines robust construction with advanced technologies to provide high accuracy over an extremely wide temperature range. The resistor is protected with a glass-filled epoxy body, a metalized layer, and a dielectric coating for additional durability and corrosion resistance. It is approved for use in demanding industrial applications and medical devices.

Application Field and Working Principle

The CMF5518M000FKEB is typically employed as a current regulator in circuit boards. With a wide temperature range and robust construction, it is designed to yield accurate readings in extreme conditions. The resistor also has a high degree of accuracy across the entire operational range. It features advanced design techniques to limit thermal variations, transient response, and power dissipation.

The resistor’s operation is based on Ohm’s Law, which states that the current through a metal conductor is in direct proportion to the voltage applied. For an ideal resistor, the voltage and current have a linear relationship. This relationship enables the resistor to convert electrical energy into mechanical energy, thereby regulating the amount of current in the circuit.

Construction Details

The CMF5518M000FKEB is typically constructed in SMD (Surface Mount Device) style. This design offers several advantages over traditional through-hole construction, including reduced weight, compact size, and easy installation. Additionally, SMD resistors have a much higher packing density than conventional ones.

The metalized layer of the resistor acts as a heat sink, absorbing excess heat to prevent overload or premature failure. The dielectric coating allows the resistor to function adequately even in environments with high levels of corrosive contaminants. Furthermore, the glass-filled epoxy housing increases mechanical strength and provides excellent noise immunity.

Usage Considerations

The CMF5518M000FKEB is designed to be durable and accurate, but its performance depends heavily on the environment in which it is used. If it is constantly exposed to temperatures beyond its specified operating range, or to contaminants such as dust and debris, it may become damaged or malfunction. It is also important to ensure that the operating conditions remain within the specified tolerances; otherwise, the resistor may not be able to provide the desired level of protection.

The CMF5518M000FKEB is also important to use the correct installation techniques. Improper installation can cause the resistor to become damaged or fail prematurely. It is also important to protect the resistor from physical shock and to ensure that the voltage level remains within the specified range. Otherwise, the resistor may become damaged or run into problems.

Conclusion

The CMF5518M000FKEB is a through hole resistor designed for use in harsh environments. It boasts excellent accuracy and a wide temperature range, and is protected by a metalized layer, a dielectric coating, and a glass-filled epoxy body. It is commonly used as a current regulator in circuit boards, and is approved for use in industrial and medical applications.

The CMF5518M000FKEB is a reliable and durable resistor, but its performance depends heavily on the environment in which it is used. Care should be taken to ensure that the resistor is properly installed and remains within the specified temperature and voltage range. Additionally, proper maintenance of the resistor is always important to ensure its long-term efficiency.
