Product Details

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

Note

The mounting brackets are sold separately: SN 7885167 for 10 x 50mm ( 25W ); SN 7885151 for 20 x 117mm ( 100W ); SN 7885154 for 25 x 168mm ( 200W ); SN 7885160 for 30 x 250mm ( 280W )
