CO32H4-20.000-33KDTSN是杭晶(HCI)推出的工业级高稳定HCMOS输出晶振,以20MHz为标称频率,兼顾精度、稳定性与小型化设计,适配对频率一致性要求较高的数字系统。产品依托杭晶成熟的晶振制造工艺,在宽温范围内保持可靠的频率输出,可满足工业控制、通信等领域的多样化需求,是替代传统晶振的高性价比方案。
采用SMD3225-4P(3.2mm×2.5mm贴片封装,4引脚),体积小巧,比传统DIP封装缩小约60%,适配高密度PCB设计,支持回流焊工艺,焊接兼容性强。
SMD3225-4P封装尺寸仅3.2×2.5mm,可有效降低系统体积,适合便携式设备、小型化模块(如智能传感器、微型控制器)等场景,满足设备轻薄化趋势。
产品经过杭晶严格的可靠性测试(高低温循环、振动、冲击等),确保在复杂环境下长期稳定工作,避免因晶振失效导致系统故障。
产品支持**-40℃~+85℃**的工业级工作温度范围,可在户外、工业现场等恶劣环境下稳定运行:
PLC(可编程逻辑控制器)、工业传感器、伺服驱动器等,需稳定时钟信号保证控制精度与通信可靠性;
路由器、交换机、无线AP、户外基站等,20MHz频率适配多种通信芯片时钟需求,宽温设计满足户外场景;
智能家居设备(智能网关、摄像头)、便携式医疗仪器(血糖监测仪、小型心电图机),小型化封装适配设备轻薄化趋势;
车载信息娱乐系统、ADAS辅助驾驶模块(非安全关键场景),宽温设计适配车内温度变化(-20℃~+85℃常见)。
CO32H4-20.000-33KDTSN凭借高稳定、小型化、宽温适应性等特点,成为多领域数字系统时钟源的优选方案,可有效提升系统可靠性与设计效率。

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.
