Vishay 1Ω 10% 200W High Power Wire-Wound Adjustable Resistor
- RS Stock No. 788-7750
- Mfr. Part No. RSSD25168A1R00KB06
- Manufacturer Vishay
25 Watt to 280 Watt RSSD Series
RSSD medium and high power resistors are noted for their ability to withstand heavy transient and severe shock and vibration
conditions. They complement the ohmic range of Vishay styles RW, RWST and RA in the low value area, and can be tapped by
means of adjustable collars. Standard RSSD resistors have a single adjustable collar.
Features:
• High power rating: 16 W to 600 W at 25 °C
• Heavy overloads 10 Pn 15 s ≤ 1 %
• Low ohmic values 0.10 Ω available
• High long-term stability drift < 1.5 % after 1000 h
• Excellent withstanding of thermal shock
• Mechanical strength
• Fire proof
