Thin Film Chip Resistors
These surface-mounted resistors make the most of their small temperature coefficient.
Features
- Superior stability, with strong moisture resistance and small changes over time.
- Superior temperature coefficient (±1ppm/°C).
- Superior high-frequency properties.
- Superior current noise properties.
- Strong resistors against surge.

How to Order
Specify the following points:
| RFC-1D | 100Ω | P(±5ppm/℃) | B(±0.1%) | -e | Ecomark or -e (can be omitted) |
| Model name | Resistance value | Temperature coefficient of resistance | Resistance value tolerance | RoHS compliance |
Omit the Ω in KΩ and MΩ. Write 10KΩ as 10K.
