2W 10 laps Multi-turn wire wound potentiometer R&L-3590S-2-201 200 ohm potentiometer

All the metal on its surface are oxides, sulfides, adsorbed gases, moisture, or the formation of thin films of organic molecules. Even after thorough cleaning, the film will soon reappear. In base metals such as copper and aluminum on the surface, this film within minutes 50 angstroms thick. Since then they should continue to thicken, until hundreds of angstroms thick, so far. Gold and platinum and other precious metals in contact will form a film, but much thinner, but also for the normal electrical connection does not cause much problem. Because of this, we use the precious metal alloys. To completely solve this problem. Figure.

3590 series R&L-3590S-2-102 Multi-turn wirewound potentiometer, is Wound, fine resistance wire evenly wound on the skeleton, and the required length or the exact value of the total resistance. Factory accuracy is maintained at 1% -2%.

Through the efforts of the company, using a resistance wire wrapped around the skeleton, an increase of the adhesive process, making the resistance wire in the frame fixed on the pitch position, in the long-term use, but also will not change, which increases the potentiometer linear stability (not in use over time, become linear, and unstable).

Brush on the potentiometer of the number of parameters have a significant impact. Contact resistance, contact resistance changes, resolution, noise, power rating, working life, and stability (under shock and vibration) are all related contacts and activities.

After years of effort the company engineers to produce a durable wire potentiometer. 10 lap series. Resistance in the linear potentiometer, activities brush, durability, reliability, stability, materials technology, there are many unique aspects. As follows:
1), activity brush using precious metals. Make contact with wire-wound potentiometer resistance, contact resistance changes, resolution, noise, power rating, working life, stability, etc. have been greatly improved.
2), resistance wire winding process, the use of glue on the craft, making the wound linear potentiometer resistance stability, longevity and reliability are greatly enhanced.
3), using the brazing process, the resistance wire to the outlet connection reliability, stability has greatly improved.
Series has the following certification:
