Description

500W Oval Shaped Silicon Coating High Power Wire Wound Resistors

Structure :

1.A flat tubular ceramic has two terminals and is wound with either copper wire or chromium alloy wire as a resistance element. It is coated with a high-temperature non-flammable resin.When cooled and dried,it is encapsulated in insulation through a high-temperature process before the final installation of the component mounts.

2.It is mainly utilized for industrial installations where height is limited.

4.Non-inductive & variable type on requests;

5.Working voltage and Nominal resistance value are related to Ohm’s law.

Features:

1.Anti-corrosion,excellent heat resistance;the resistor has small temperature coefficient and linear change.
2.It is normal that the resistor is smoking when it used in the first power.
3.Due to the excellent windings, many taps can be added, impedance is low,and PC board is insertable,and usable for many other integrated applications.
4.For custom specifications, please contact us to discuss the details.
5.Support precision resistance tolerance requirement.
