Typical Applications & Why This Part Fits

• Power supply decoupling in IoT modules: The 2.2µF capacitance at 10V provides effective noise suppression for low-voltage (1.8V–5V) rails, while the X7R temperature stability (–55 to +125°C) suits outdoor sensors.
• DC-DC converter output filtering: Its 0603 footprint allows dense placement near converters, and the 10V rating exceeds typical 3.3V/5V outputs with safety margin.
• Audio coupling in portable devices: The ±10% tolerance ensures consistent audio signal pass-through, and the 2.2µF value is ideal for audio path AC coupling in smartphones or wearables.

Key Features & Advantages

• High volumetric efficiency: 2.2µF in a 0603 case delivers more capacitance per board area than larger packages, enabling slimmer end products.
• Wide operating temperature range: X7R dielectric guarantees capacitance variation within ±15% from –55°C to 125°C, suitable for automotive or industrial environments.
• Low equivalent series resistance (ESR): MLCC construction yields low ESR, improving high-frequency ripple suppression and transient response in power circuits.
