Murata CSTNE12M0G550000R0 12MHz Ceramic Resonator (Built-In Capacitors, 3.2x1.3mm SMD)

Simplify your microcontroller clock circuitry and conserve PCB space with the CSTNE12M0G550000R0 12MHz ceramic resonator from Murata. Standard quartz crystals require two external load capacitors ($C_1$ and $C_2$) to establish a stable oscillation loop. Murata’s CSTNE series eliminates these extra components by integrating built-in load capacitors directly inside the package, streamlining your bill-of-materials (BOM) and saving precious board area.

Operating at a core system frequency of 12.000 MHz, this 3-pin surface-mount resonator features a central ground pin that connects the internal capacitor grounds directly to your board plane. This design delivers rapid oscillator startup times and reliable clocking for main microcontrollers, USB-to-UART bridge chips (CH340/CP2102), automotive sub-systems, and industrial control electronics.

Key Features:

• Integrated Load Capacitors: Built-in capacitors remove the need for external passive loading components, reducing component count and routing complexity.

• 12.000 MHz Core Frequency: Essential timing reference widely used in USB peripherals, microcontrollers, and digital system clocks.

• 3-Pin Grounded Architecture: Center pin routes internal capacitor grounds straight to the PCB ground plane for superior noise immunity and fast startup.

• Compact 3213 SMD Package: Low-profile 3.2 x 1.3 mm footprint offers high mechanical shock resistance and thermal durability.
