SX3M18.432A20F30TNN

Oscillators Overview

The SX3M18.432A20F30TNN is a quartz crystal resonator manufactured by Shenzhen SCTF Electronics, designed for precision frequency generation in electronic circuits. This component operates at a fundamental frequency of 18.432 MHz and utilizes an AT-cut quartz resonator element to ensure stable oscillation characteristics across varying environmental conditions. The device is housed in a surface-mount SMD package, specifically the 6-lead SC-70 (SOT-323) form factor, which facilitates automated assembly and compact board layouts. It features a load capacitance of 20 pF and a frequency tolerance of ±30 ppm, making it suitable for applications requiring reliable clock signals without active temperature compensation.

Oscillators Feature Summary

• Provides precise 18.432 MHz frequency output using AT-cut quartz technology
• Utilizes a compact 6-lead SC-70 surface-mount package for space-efficient integration
• Maintains frequency stability with a ±30 ppm tolerance under standard operating conditions

Oscillators Applications

• Clock source generation for microcontrollers and digital logic circuits
• Frequency reference for communication modules and data transmission interfaces
• Timing synchronization in portable consumer electronics and embedded systems

Oscillators Procurement Notes

Verify the specific manufacturer part number against official distributor catalogs to confirm availability and authenticity. Ensure that the required load capacitance and tolerance specifications align with the target circuit design before finalizing procurement orders. Cross-reference datasheets for thermal performance limits and soldering reflow profiles to guarantee component reliability during assembly processes.

Oscillators Selection Notes

Select this component when a stable, low-cost frequency reference is needed for general-purpose digital timing applications. The SC-70 package is appropriate for high-density PCB designs where space constraints are critical. Consider the ±30 ppm tolerance as sufficient for most standard UART, SPI, or I2C baud rate generation tasks, provided the system does not require ultra-high precision timing accuracy.

Oscillators Part Context

This crystal resonator belongs to the family of passive frequency control components used in modern electronics. Unlike oscillator modules, it requires an external active circuit to generate a signal. The 18.432 MHz frequency is a common choice for serial communication standards due to its divisibility into standard baud rates. The SC-70 footprint ensures compatibility with standard SMT pick-and-place equipment used in mass production environments.

Oscillators Replacement Considerations

Substitute parts must match the 18.432 MHz frequency, 20 pF load capacitance, and SC-70 package dimensions. Verify equivalent tolerance ratings and operating temperature ranges from other manufacturers such as Murata, Abracon, or TXC to ensure functional interchangeability in existing designs.
