  1. FRSM Z-1 foil technology ultra high-precision wrap-around chip resistor series

    FRSM Z-1 foil technology ultra high-precision wrap-around chip resistor series

    The FRSM ultra high precision resistor series utilises the new Z-1 foil technology for improved load life stability and higher working temperatures. These resistors have nominal temperature coefficients of resistance of ±0.05ppm/°C typical between 0°C to +60°C and ±0.2ppm/°C typical between -55°C to +125°C (+25°C reference) with tolerances available down to ±0.01% between 250Ω and 125KΩ.

    • Available in 0603, 0805, 1206, 1506, 2010 and 2512 chip sizes
    • Available in resistance values between 5Ω to 125KΩ depending on chip size
    • Tolerances down to ±0.01% between 250Ω and 125KΩ
    • Load life stability of ±0.0025% at +70°C after 2,000 hours at rated power
    • Electrostatic discharge (ESD) at least to 25kV

  2. FRSM Z-1 foil technology ultra high-precision wrap-around chip resistor series (EEE 'space qualified')

    FRSM Z-1 foil technology ultra high-precision wrap-around chip resistor series (EEE 'space qualified')

    The FRSM EEE space qualified ultra high precision resistor series utilises the new Z-1 foil technology for improved load life stability and higher working temperatures. These resistors have nominal temperature coefficients of resistance of ±0.05ppm/°C typical between 0°C to +60°C and ±0.2ppm/°C typical between -55°C to +125°C (+25°C reference). The 303261 through 303266 models all offer full wrap-around terminations which ensures reliable handling during the manufacturing process, as well as providing stability during multiple thermal cycles.

    • Available in 0603 (303261 model), 0805 (303262 model), 1206 (303263 model), 1506 (303264 model), 2010 (303265 model) and 2512 (303266 model) chip sizes
    • Available in resistance values between 10Ω to 75KΩ depending on model
    • Tolerances down to ±0.02% between 250Ω and 75KΩ
    • Load life stability of ±0.02% after 2,000 hours at +70°C at rated power
    • Tested per EEE-INST-002 and MIL-PRF-5534
