Category: Chip ResistorDescription: 100W / 200W Thick film power resistor - RTOP series Vishay Sfernice RTOP series thick film non inductive resistor, using SOT-227B package resistor installed on the heat sink, allows dissipation of (RTOP 100) or 200W (RTOP 200) at 25 ° C Power consumption at 25 ° C: | 100 W (RTOP 100); 200 W (RTOP 200) --- | --- Tolerance: | ± 5% Temperature coefficient: | R 1 Ω: ± 150 ppm/° C Maximum service voltage: | 1500 V Effective voltage Thermal resistance: | 1 ° C/W (RTOP 100); 0.5 ° C/W (RTOP 200) Shell: | SOT-227B Connection: | Use screws M4 x 6 size - Sfernice series| RCH 5 | RCH 10 | RCH 25 | RCH 50 L | 16.6 | 19 | 28 | 50 W | 9 | 11 | 14 | 15.5 H | 16.4 | 20.6 | 27.5 | 29.4 P | 10.2 | 12.7 | 18.3 | 33 F | 11.3 | 14.3 | 18.3 | 39.7 T | 12.5 | 15.9 | 19.8 | 21.4 S | 5.3 | 5 | 7.7 | 8 Ø D | 2.4 | 2.4 | 3.2 | 3.2 | M2 | M2 | M3 | M3 Main Features - Overload Duration| RCH25 | RCH50 | BDS100 | BDS250 1 s | 375W | 750W | 200W | 1500W 2 s | 300W | 600W | 150W | 1250W 5 s | 125W | 250W | 125W | 1000W 10 s | 75W | 150W | 100W | 750W For every one degree increase in ambient temperature above 25 ° C, the allowable overload is reduced by 1%. The main feature table is only applicable to resistors appropriately installed on heat sinks, with a thermal resistance of 1 ° C/W at rated powers of 25 and 50W, 0.7 ° C/W at rated power of 100W, and 0.28 ° C/W at rated power of 250W. This data is only valid when hot oil grease is used and the resistor is correctly tightened by the mounting screw.
