1553H-32K768J50DTSL 是杭晶(HCI)推出的一款高精度 32.768kHz 晶体振荡源,采用 SMD5032-4P 表贴封装。输出为 HCMOS 电平,工作电压宽泛(2.5V~5V),面向对时钟精度与稳定性有较高要求的便携与工业级应用,具有高可靠性与稳定的频率特性。
本器件在常温条件下提供 ±10 ppm 的初始频差,整机应用中配合适当的校准可实现高精度计时。±20 ppm 的频率稳定度覆盖器件在工业温度范围内的温漂表现。HCMOS 输出能直接驱动后端数字电路,适配常见微控制器与计时器输入。
SMD5032-4P 小尺寸封装便于贴片加工与高密度 PCB 布局,适用于回流焊工艺。杭晶在材料选用与制造过程中对可靠性做严格控制,适配宽温环境保证长期稳定性与一致性,适合工业级产品设计。
在系统设计中,请根据供电电压选择合适的工作点并注意去耦与地线设计,以保证 HCMOS 输出的信号完整性。若对功耗有更高要求,可结合系统唤醒/休眠策略优化平均功耗。订购时请确认封装型号(SMD5032-4P)与品牌(HCI/杭晶)以保证规格一致性。

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.
