GS = (Fixed Film Resistor High Stability)
Power Rating
3 = 3W @ 25°C / 2W @ 70°C
TCR Characteristics
50 = ±50 pmm/°C
100 = ±100 pmm/°C
200 = ±200 pmm/°C
(available on values greater than 10 ohms)
Resistance Value
(100 ohms and greater - First 3 significant digits plus 4th digit multiplier)
Example: 100 ohms = 1000, 1000 ohms = 1001, 150,000 ohms = 1503
(Less than 100 ohms - "R" is used to designate decimal)
Example: 51 ohms = 51R0, 1 ohm = 1R00, 0.25 ohms = R250
Tolerance
F = ±1%, G = ±2%, J = ±5%
RoHS Compliance
LF = RoHS-compliant product
