Features: 1. Shockproof, moisture resistant, heat resistant and good heat dissipation 2. Completely insulated for printed circuit boards 3. On the porcelain rod, the wire is wound and then the joint is welded, which can produce accurate resistance value and prolong life. 4. The high resistance value is made of metal oxide film body (MO) instead of winding method, and the performance is stable. 5. Excellent heat resistance, small temperature coefficient of resistance. 6. Short-time overload, low noise, no change in resistance over the years. 7. Explosion-proof performance can protect the cement resistor Specification: Condition: 100% Brand new Item Type: Cement Resistor Accuracy: 5% Power: 20W Package Size: Approx. 20 x 10 x 3cm / 7.9 x 3.9 x 1.2in Optional Style: 1R, 1.5R, 2R, 2.2R, 3R, 5R, 8R, 10R, 12R, 15R, 20R, 30R, 50R, 100R, 120R, 150R, 1KR, 2KR, 3KR, 10KR Package List: 10 x Cement Resistor 1Shockproof, moisture resistant, heat resistant and good heat dissipation 2Completely insulated for printed circuit boards 3On the porcelain rod, the wire is wound and then the joint is welded, which can produce accurate resistance value and prolong life. 4The high resistance value is made of metal oxide film body (MO) instead of winding method, and the performance is stable. 5Excellent heat resistance, small temperature coefficient of resistance.
