Epoxy Conformal Coated R.F. Chokes from Philmore Manufacturing
A choke is an inductor used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency or direct current (DC).
Tri-Tek offers the Philmore line of axial lead small chokes, slightly larger than resistors and marked with the same code as resistors to indicate value. Epoxy coating makes them nearly impervious to moisture, humidity, etc.
