TE Connectivity 18kΩ Metal Oxide Resistor 3W ±5% ROX3SJ18K

The ROX3S Series of Power Metal Oxide Film Resistors from TE Connectivity provide high power with a compact, space-saving size. The ROX3S series is ideal for line protection applications, they are flame proof as well as being able to withstand overload conditions. Their excellent long-term stability allows for assuring in application as well as providing reliability over time.

The resistors are compatible for processing on automatic insertion equipment as well as with cutting and bending machines.

• High power in a compact form
• Excellent long-term stability
• 3W Rated dissipation at 70°C
• ±5% Resistance tolerance
• ±300ppm/°C Temperature coefficient
• 350V Limiting element voltage
• 600V (max.) Overload voltage
• 1000MΩ Insulation resistance

The ROX series of resistors comprise of a metal oxide film deposited onto a high quality alumina former. Attention to materials and processing quality allow a reduced physical size for each of the three power ratings with very good long term stability. The end cap and welded wire construction ensure high mechanical stability and strength. A specially formulated coating protects the element from environmental conditions and will withstand overload conditions without flame or mechanical damage. Recommended uses include all applications where overload conditions must not cause flaming. Value and tolerance markings is by four band colour code in accordance with IEC62. Rated at 70°C mounted horizontally in free air. Climatic category 55/235/56.
