Chassis mount resistors provide electrical resistance to control current flow in a circuit, and TMC0505K000FE02 is a kind of them. Its application field and working principle will be discussed in this article.

Application Field

The TMC0505K000FE02 is a resistive component used for voltage divider circuits, active filters, signal attenuators, and impedance matching to load or drive other circuits.The resistor has a 5% tolerance, medium temperature coefficient, and 2 watts of power dissipation. Thus it is suitable for applications where small variations in resistance value and large temperature changes are acceptable. It is also an ideal solution for applications where the load or the drive circuit must be provided with an isolate resistor to avoid the occurrence of false triggering in sensitive logic circuits.

Working Principle

The TMC0505K000FE02 uses metal-oxide-semiconductor (MOS) technology to control the flow of current through the resistor. The MOS structure is composed of two layers of metal separated by a thin film of semiconducting material. When a voltage is applied to the MOS contacts, a small current will flow through the semiconductor layer, which affects the resistance value on the outside of the resistor. The resistor offers a range of resistance values to allow for a selection of resistance values and has a low internal noise level.

The resistor also has a small internal capacitance which is used to filter out unwanted signal noise from the circuit. The internal capacitance combined with the high resistance value of the MOS structure ensures the resistor provides excellent signal filtering performance.The resistor is also designed to be highly reliable and has an operating temperature range of -40 to +125 C. The resistor is also lead-free and RoHS compliant, making it suitable for use in a wide range of applications.

Conclusion

In conclusion, the TMC0505K000FE02 is a versatile resistive component that offers excellent signal filtering performance for voltage divider circuits, active filters, signal attenuators, and impedance matching. It features a 5% tolerance, medium temperature coefficient, and two watts of power dissipation, which makes it suitable for applications where small variations in resistance values and large temperature changes are acceptable.
