The MB ultra-precision transfer moulded resistor series from Alpha Electronics offers a wide resistance range from 5Ω up to 400kΩ with tight tolerances, all in a small through-hole package with a pin pitch of 7.5 ±0.5mm. By utilising Alpha’s Bulk Metal® foil resistor technology, they are able to produce resistors with low temperature coefficients and excellent long-term stability.
Alpha’s Bulk Metal® foil resistor technology means that these transfer moulded, through-hole, ultra-precision resistors are ideal for precision measurements, also their low inductance makes them ideal for use at higher frequencies.
These resistors are constructed using an outer coating of transfer moulded epoxy resin, making the parts strongly resistant to heat, moisture and solvents. Internally, there are secondary leads which act as a buffer so that stress on the exterior leads is not transmitted to the foil, providing stability against vibrations when the resistor is mounted on a circuit.
