Alpha MCTF Series

The MCTF precision thin film resistor series from Alpha Electronics offers a wide resistance range from 200kΩ up to 10MΩ with tight tolerances from ±0.01% up to ±0.1%, all in a small through-hole package with a pin pitch of 3.81 ±0.25mm.

Alpha’s Bulk Metal® foil resistor technology means that these transfer moulded, through-hole, ultra-precision resistors are ideal for precision measurements. 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.
