The MQP Z-foil resistor series from Alpha Electronics offers ultra high-precision including a TCR of ±0.2 ppm/°C (typical) as well as a wide resistance range from 30Ω up to 40kΩ, all in a small surface-mount package. By utilising Alpha’s Z-foil resistor technology, they are able to produce resistors with a temperature coefficient of almost zero and excellent long-term stability. Expanding on the standard Alpha MQ series, the MQP series offers double the power rating at +70°C and the same power rating up to +125°C. The 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.

Alpha’s MQP surface-mount, ultra high-precision resistor series exhibit excellent high frequency characteristics thanks to their new generation Z-foil technology, making them suitable for the most demanding precision applications.
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.
