SX7M25.000M20F30TNN是星通时频(SCTF)推出的工业级CMOS有源晶振,针对需要高稳定性时钟源的电子系统设计,覆盖嵌入式、通信、物联网及工业控制等多领域。其宽温宽压特性使其能适配从消费电子到户外工业设备的多样化场景,是替代传统无源晶振或低性能有源晶振的高性价比选择。
该晶振的核心参数围绕“稳定性、兼容性、低功耗”三大核心需求设计,具体如下:
该晶振采用SMD7050-4P表贴封装,尺寸为7.0mm×5.0mm×1.5mm,具备以下特点:
工作温度覆盖**-40℃~+85℃**(工业级温度规格),可适应户外传感器节点(冬季低温)、工业控制柜(夏季高温)等极端环境,无需额外温控措施。
为STM32F4、ATmega328P等MCU提供系统时钟,确保UART通信波特率稳定(误差≤0.1%)、ADC采样时序准确,适配工业PLC、智能控制器等设备。
作为ESP32(Wi-Fi)、nRF52832(蓝牙)模块的参考时钟,保证2.4GHz频段通信速率稳定,减少丢包率(实测丢包率≤0.5%),适配智能门锁、环境监测节点。
在-40℃~+85℃环境下为温度、压力传感器提供采样时序,支持远程数据传输的同步性(误差≤1ms),适配油田、矿山等户外监测设备。
用于智能手表、智能家居控制器,满足1.8V电池供电需求,同时提供稳定时钟(待机功耗可通过NC引脚控制),延长设备续航。
SX7M25.000M20F30TNN以高稳定性、宽适配性、工业级可靠性为核心优势,覆盖从消费电子到工业控制的多场景需求,是中小批量电子系统时钟源的优选方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
