The FLB high precision through-hole resistor series from Alpha Electronics offers a very precise resistor with a resistance range from 1Ω up to 150kΩ all in a small through-hole package. The terminals have been designed for easy insertion into the PCB. By utilising Alpha’s Bulk Metal® foil resistor technology, they are able to produce resistors with low-temperature coefficients and excellent long-term stability. This makes them ideal for precision measurements, also their low inductance enables use at higher frequencies.
