Thin film resistor technology
- Reduce the cross talk& EMI effect
- Excellent long-term reliability
- Reduce the board height & unit size
Good process control
- Resistance value per square

| Symbol | Material Resistivity | Unit | 50 Ohm/□ | |
| - | Material Tolerance | % | ± 5 | |
| A | Resistor Length @ 100 Ohm | um | 300 | |
| B | Min Resistor Width @ 100 Ohm | um | 150 | |
| C | Min Space between trace & Resistor | um | 125(Normal) | 80(Advanced) |
| D | Min Tail Length | um | 65(Nominal) | 40Advanced) |
| LW/LS | Line width/Space(subtractive process) | um | 40/40 | 35/35 |
| - | Overall Resistance Tolerance | % | ± 20 | |

Formula: Resistor value = 50 Ω/□ x (300 um/150 um) = 50 Ω/□ x 2 squares = 100 ohms |
