- Compact size: 0204 package (SFR16S series)
- Low noise performance (≤ 1.5 µV/V for R > 1 MΩ)
- Excellent temperature stability
- High reliability due to protective lacquer coating (light-blue)
- Resistant to cleaning solvents (IEC 60068-2-45 compliant)
- Compatible with both Pb-free and leaded soldering processes
Construction Details
- Resistive element: deposited metal alloy film
- Substrate: high-grade ceramic body
- Trimming: helical groove for precise resistance adjustment
