Y6OGC-STU-32.768K 作为标准的 32.768 kHz 石英晶体,具有以下明显特性:
Q:负载电容如何选择?
A:晶体规格标注的等效负载电容 CL = 12.5 pF,系统上两侧的电容 C1、C2 与电路板走线电容(Cstray)共同决定实际负载。常用计算关系为: CL = (C1 × C2) / (C1 + C2) + Cstray 若取 C1 = C2,则近似有 C1 ≈ 2 × (CL − Cstray)。
经验值:若板上寄生电容 Cstray ≈ 2–5 pF,建议两侧电容取 22 pF(或 18–22 pF 工艺上微调),以便达到 12.5 pF 的等效负载。
布局建议:
驱动与电平:
无源晶体应搭配 MCU 内部的晶体振荡电路使用,推荐采用低驱动电平以延长晶体寿命并降低频率漂移。参考 MCU 厂家关于晶体驱动级别的建议进行配置。

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.
