SMR1DZ/SMR3DZ (Z-Foil)
Unique flexible terminations ensure minimal stress transference from the PCB due to a difference in temperature coefficient of expansion (TCE)
Features:
- Ultra high-precision Z-Foil molded surface mount resistor
- Temperature coefficient of resistance (TCR):
- 0.05 ppm/°C typical (0°C to +60°C)
- 0.2 ppm/°C typical (-55°C to +125°C, +25°C ref.)
- Resistance tolerance: to ±0.01%
- Power coefficient of resistance (PCR) “∆R due to self-heating”: 5 ppm at rated power
- Load life stability: to ±0.005% (+70°C, 2000 hours at rated power)
- Power rating: to 600 mW at 70°C
- Matched sets with TCR tracking are available upon request
- Electrostatic discharge (ESD) at least to 25 kV
- Thermal stabilization time <1 s (nominal value achieved within 10 ppm of steady state value)
- Rise time: 1 ns effectively no ringing
