The CSTCR7M37G53-R0 is a 7.37 MHz ceramic resonator from Murata's CERALOCK® CSTCR series, designed as a compact, cost-effective replacement for crystal oscillators in microcontroller clock circuits. This surface-mount timing device features built-in load capacitors that eliminate the need for external components, simplifying circuit design and reducing board space. With a frequency tolerance of ±0.5%, stability of ±0.2%, resonant impedance of 50Ω, and thickness-shear mode oscillation, this 3-pin SMD resonator measures just 4.5 × 2.0 × 1.15 mm and operates across -20°C to +80°C, making it an ideal clock source for consumer electronics, industrial controls, and communication interfaces where precision, size, and cost must be balanced.
Application Scenarios
● Microcontroller clock generation: providing the primary timing reference for 8-bit, 16-bit, and 32-bit MCUs in embedded systems where crystal-level precision is unnecessary.
● USB controller ICs: serving as the clock source for USB interfaces and peripheral controllers requiring stable, low-cost timing.
● Audio equipment: clocking digital signal processing blocks in consumer audio devices where cost and size outweigh ultra-precision requirements.
● Communication modules: timing reference for UART, I²C, and other serial interfaces in IoT devices and sensor networks.
● General consumer and industrial electronics: replacing discrete RC/LC oscillators and crystal oscillator modules in appliances, toys, and control boards seeking simplified timing.
FAQ
Q: What is the difference between CSTCR7M37G53-R0 and CSTCR7M37G55-R0? A: Both operate at 7.37 MHz in identical packages; the G55 variant offers slightly different built-in capacitance values to match specific IC input characteristics.
Q: Can this resonator replace a crystal oscillator directly? A: Yes, it serves as a cost-effective crystal substitute with looser tolerance (±0.5% vs. ±10-50 ppm for crystals), suitable for applications not requiring ultra-precise timing.
Alternative timing component Models
● CSTCR7M37G55-R0: The same-frequency CERALOCK variant with different built-in capacitance, offering drop-in compatibility for ICs requiring adjusted load conditions.
● CSTLS7M16G53-A0: A CSTLS-series ceramic resonator in a larger through-hole-friendly SMD package, providing similar performance with different mechanical footprints.
● CSTCE8M00G55-R0: Murata's smaller-footprint CSTCE series resonator for ultra-compact designs requiring a different frequency point.
● ECS-160-8-30-JTN-TR: ECS Inc.'s ceramic resonator alternative with comparable frequency options in a similar SMD package for multi-source procurement.
