SX5A8.000F2010F30G是星通时频(SCTF)推出的一款高性能无源石英晶体谐振器,专为需要稳定时钟基准的中低端至中端电子设备设计。其采用SMD5032小型封装,兼顾空间节省与可靠性,核心参数匹配多数消费电子、工业控制及通信设备的时序需求,是替代同类进口晶振的高性价比选择。
这款晶振属于无源设计(无需额外供电),核心特征可总结为:
标称频率8MHz是电子设备中通用系统时钟基准(如路由器、机顶盒的主时钟);常温频差±10ppm意味着在25℃环境下,实际频率波动范围为8MHz±80Hz,可满足多数常规应用的时序精度需求(如数据传输、指令同步)。
20pF是无源晶振的典型负载值,设计时需在晶振两端并联20pF左右的陶瓷电容(可根据实际电路微调),以保证振荡频率与标称值一致;无源晶振无需额外电源,仅需芯片内部振荡电路驱动即可工作。
±30ppm的频率稳定度,指工作温度从-40℃到+85℃时,频率相对于常温的最大波动范围(8MHz±240Hz),可覆盖多数工业级设备的温区要求(如户外传感器、控制柜内模块)。
100Ω的等效串联电阻处于无源晶振的合理范围:过低ESR可能导致振荡过强、功耗增加,过高则易因能量损耗过大停振;该参数在全温区内保持稳定,提升了长期工作可靠性(尤其适合连续运行的设备)。
SMD5032-2P封装尺寸为5.0mm×3.2mm×1.2mm(典型值),采用2引脚贴片式设计,兼容标准SMT贴装工艺(可使用普通贴片机生产),适合高密度PCB布局(如小型蓝牙模块、智能手环)。
SX5A8.000F2010F30G的参数与封装特性,使其适用于以下场景:
星通时频(SCTF)是国内专注于石英晶体器件的厂商,拥有10余年生产经验,SX5A8.000F2010F30G经过严格可靠性测试:
产品供货稳定,支持样品申请与批量定制(如调整频差、封装),适合中小批量至大规模生产应用。
综上,SX5A8.000F2010F30G是一款高性价比无源贴片晶振,兼顾精度、可靠性与成本,可满足多数常规电子设备的时钟需求。
Request for quote
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.
