SX3B12.000F1210G30

Crystals Overview

The SX3B12.000F1210G30 is a passive AT-cut crystal oscillator manufactured by Shenzhen SCTF Electronics. It operates at a fundamental frequency of 12 MHz with a standard load capacitance of 12 pF. The component features a 4-SMD, no-lead surface mount package and exhibits a maximum equivalent series resistance (ESR) of 100 Ohms. Frequency stability is rated at ±30 ppm, and the device supports an operating temperature range from -40°C to +105°C.

Crystals Feature Summary

• AT-cut crystal structure for high precision
• Ultra-small ceramic surface mount package with metal cover
• Designed for high temperature and high accuracy applications

Crystals Applications

• General electronic circuits requiring precise timing
• Microcontroller clock sources
• Communication equipment signal generation

Crystals Procurement Notes

Verify that the ordering suffix 'G30' corresponds to the required ±30 ppm stability specification rather than other tolerance levels. Confirm the 4-SMD footprint dimensions match the target PCB layout. Ensure the supplier provides documentation confirming the lead-free status and RoHS compliance for the specific batch.

Crystals Selection Notes

Select this component when a 12 MHz reference with ±30 ppm stability is required in a compact SMD form factor. The 12 pF load capacitance must align with the host circuit's design requirements. Consider the -40°C to +105°C temperature range for industrial or automotive environments where standard commercial grades are insufficient.

Crystals Part Context

This part belongs to the SX3B series of ultra-small ceramic surface mount crystals from Shenzhen SCTF Electronics. The series utilizes AT-cut technology to ensure stability across wide temperature variations. The model designation indicates a 12 MHz frequency, 12 pF load, and specific packaging characteristics defined by the manufacturer.
