The CSTCE8.00G15A3J-R0 is a MHz-band ceramic resonator (CERALOCK) from Murata Electronics’ CSTCE series. Operating at 8.000 MHz with ±0.3% frequency tolerance, this resonator features built-in load capacitance of 15pF, eliminating the need for external capacitors and simplifying PCB design. The compact 3.2 x 1.3 x 0.8 mm SMD package enables high-density mounting, making it ideal for space-constrained applications. The three-terminal structure provides stable oscillation for microcontroller clock circuits. As a cost-effective alternative to quartz crystals, CERALOCK resonators offer adequate frequency stability for applications where ±2-3% precision is sufficient under working conditions.

The CSTCE8.00G15A3J-R0 operates as a piezoelectric ceramic resonator:

1. Piezoelectric Effect: The ceramic element vibrates at its mechanical resonant frequency when an electric field is applied, generating a stable frequency signal through the inverse piezoelectric effect.

2. Built-in Capacitance: The resonator incorporates internal load capacitors (CL1=CL2=15pF) between the oscillation terminals and ground, eliminating the need for external capacitors in the oscillator circuit.

3. Oscillation Circuit: When connected to an amplifier (typically inside a microcontroller), the resonator forms a feedback loop that sustains oscillation at the nominal 8.000 MHz frequency.

4. Frequency Stability: The ±0.3% initial tolerance, ±0.3% temperature shift, and ±0.3% aging characteristics together determine the total frequency accuracy over the product lifetime.

Pin Name Type Function
1 IN Input Connected to oscillator amplifier input (with built-in capacitor to GND)
2 GND Ground Common ground connection
3 OUT Output Connected to oscillator amplifier output (with built-in capacitor to GND)

Note: The three-terminal configuration incorporates built-in load capacitors between pins 1-2 and pins 3-2. Conformal coating or washing of the component is not acceptable as they are not hermetically sealed.

Application Circuit Role Key Requirement
MCU Clock Primary clock source for 8MHz microcontrollers ±0.3% tolerance, built-in caps
Automotive ECU Controller clock generation -40°C to +85°C, reliable startup
Consumer Appliance Microcomputer timing reference Cost-effective, no external caps
IoT Device Low-power MCU clock Compact 3.2×1.3mm, 11mg weight
