- Twelve wattage ratings
- Seven package sizes
- Two mounting designs to accommodate your soldering process
- Five power resistor technologies to optimize your operating perfor - mance: 1. Carbon and Ceramic composition for surge and low inductance 2. Metal film for high ohmic value and low T.C. 3. Wire element for inrush current combined with low ohmic values. Resistance values as low as 0.005Ω 4. Power film for high ohmic value and high wattage 5. High Voltage thick film for high voltage applications
