Overview

Description

The 1206L050YR is a surface-mount (SMD) multilayer ceramic capacitor (MLCC) from Yageo, part of the CC series. Key features:
- Size: 1206 package (3.2mm × 1.6mm).
- Capacitance: 5pF (±5% tolerance).
- Voltage Rating: 50V.
- Dielectric: Class I (C0G/NP0), offering high stability, low losses, and minimal capacitance drift with temperature/voltage.
- Applications: High-frequency circuits, RF filters, oscillators, and precision timing circuits.
Its lead-free and RoHS-compliant construction makes it suitable for modern electronics. The "YR" suffix may indicate specific packaging or tape/reel options.
For exact specs, refer to the Yageo datasheet.
