1/2 Watt Metal Film Resistor
There are numerous points that distinguish the RA series “audio grade” metal film resistors, from generic industrial grade parts.
1) Non-magnetic components - end caps, etc.
2) Extremely Controlled Spacing thru the spiral cutting/trimming process
3) Rigorous Testing - particularly when ensuring the parts meet their exacting
4) North American made, using premium materials
5) Extremely low TCR (Temperature Coefficient or Resistance) - 25ppm
