Murata CSTNE8M00G55A000R0 8MHz Ceramic Resonator (Built-In Capacitors, 3.2x1.3mm SMD)

Streamline your microcontroller clock circuits with the CSTNE8M00G55A000R0 8MHz ceramic resonator from Murata. Traditional quartz crystals require two external load capacitors ($C_1$ and $C_2$) to form a stable oscillator loop. Murata’s CVALS/CSTNE series simplifies board design by integrating built-in load capacitors directly inside the resonator package. This built-in configuration eliminates external passive components, saving precious PCB real estate and reducing bill-of-materials (BOM) complexity.

Operating at a core system frequency of 8.000 MHz, this 3-pin surface-mount resonator features a central ground pad that routes internal capacitor grounds directly to your board plane. It provides fast startup times and reliable clocking for main microcontrollers (such as ATmega328P, STM32, PIC, and AVR), CAN bus controllers, automotive peripherals, and industrial control nodes.

Key Features:

• Integrated Load Capacitors: Built-in capacitors eliminate the need for external $C_1/C_2$ passive components, saving board space and routing complexity.

• 8.000 MHz Core Frequency: Standard clock frequency widely supported by 8-bit, 16-bit, and 32-bit microcontrollers.

• 3-Pin Built-In Ground Layout: Central pin connects internal capacitor grounds directly to PCB ground for superior noise immunity and fast startup.

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