The MQ ultra-precision surface-mount resistor series from Alpha Electronics offers a wide resistance range from 30ฮฉ up to 60kฮฉ with tight tolerances down to ยฑ0.05% (100ฮฉ to 60kฮฉ), all in a small surface-mount package. By utilising Alphaโ€™s Bulk Metalยฎ foil resistor technology, they are able to produce resistors with low-temperature coefficients and excellent long-term stability. The Alpha MQ series J-lead terminals provide flexibility compared to standard fixed surface-mount resistors as the resistive element internally is mechanically isolated from the leads via gold wire-bonding.
These resistors are constructed using an outer coating of epoxy resin, which provides excellent resistance to moisture, heat and solvents. Internally, the resistive element is mechanically isolated from the lead frames using gold wire bonding. The series exhibits excellent high-frequency characteristics thanks to their Bulk Metalยฎ foil resistor technology, making them suitable for the most demanding precision applications.

  • Surface-mount ultra-precision resistor
