50W100 Ohm J Non-Flammable Flat High Power Wirewound 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.
6.Due to the excellent windings,many taps can be added,impedance is low,and PC board is insertable,and usable for many other integrated.
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.
