SX3B12.000F1210F30是星通时频(SCTF) 推出的通用型无源贴片晶振,采用SMD3225-4P小型化封装,核心频率12MHz,针对消费电子、工业控制、通信等多场景的稳定时钟需求设计,兼具精度、可靠性与适配性。
该产品属于无源晶振范畴(无内置驱动电路,依赖外部振荡电路谐振),核心定位为中小尺寸、工业级温度范围的通用时钟基准。相比有源晶振,无源设计成本更低、可靠性更高;相比大尺寸晶振,SMD3225封装更适配便携设备小型化趋势,可替代同规格进口晶振,满足从消费电子到工业现场的多样化需求。
负载电容为12pF,是无源晶振振荡电路的关键设计参数。该值为行业通用标准,需与外围两个匹配电容(通常为12pF左右)配合,抵消电路寄生电容后实现谐振。无需额外复杂调试,可直接适配多数主流芯片的内置振荡单元,缩短产品研发周期。
ESR控制在100Ω以内,处于无源晶振的合理区间:
采用SMD3225-4P封装(尺寸3.2mm×2.5mm),4引脚贴片设计:
该晶振因参数均衡、适配性强,广泛应用于以下场景:
星通时频(SCTF)是国内专业频率器件制造商,拥有多年晶振研发生产经验,产品通过ISO9001质量体系认证,批量供货稳定,可提供样品测试与技术支持(如振荡电路匹配建议),适合中小批量到大规模生产需求。
整体来看,SX3B12.000F1210F30以“高精度、宽温适配、小尺寸、高性价比”为核心优势,是替代进口同规格晶振的可靠选择,可满足多领域电子设备的稳定时钟需求。

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.
