kVRMS
Key Features and Benefits
- Offer the widest range of high-performance power thick
film resistors
- LTO100, DTO and D2TO are AEC-Q200 qualified with superior pulse energy
handling
- Thick film resistors are lighter than wirewound devices
with similar electrical parameters
Advantages
- Excellent pulse-energy handling
- Excellent reliability and performance (to minimize high
repair / maintenance costs)
Market Position
- Widest range of thick film power resistors
- Vishay LTO100, DTO, and D2TO devices provide pulse power handling that is superior to competition
- Vishay LPS devices provide high power ratings in
smaller and lighter packages
