Q13FC13500002 产品概述
一、产品简介
Q13FC13500002 为爱普生（EPSON）出品的贴片无源晶振，型号封装为 SMD3215-2P，标称频率 32.768 kHz，专为低功耗实时时钟（RTC）、手表、计时器及其他需高稳定时基的电子装置设计。该器件为无源晶体器件，需要与 MCU 或专用振荡器电路配合使用，具备极低功耗与良好的长期频率稳定性。
二、主要性能特点
- 标称频率：32.768 kHz，适配常见 RTC 振荡输入。
- 常温频差：±20 ppm（室温基准），满足大多数中高精度时间基准需求。
- 负载电容（CL）：7 pF，为设计外部匹配电容提供基准。
- 等效串联电阻（ESR）：70 kΩ（70,000 Ω），典型低频晶体阻抗特性。
- 工作温度范围：-40 ℃ ~ +85 ℃，适用于工业级温度环境。
- 封装：SMD3215-2P，适配自动贴装与回流焊工艺。
三、典型应用场景
- 实时时钟（RTC）模块与微处理器低速振荡器输入。
- 可穿戴设备与电子手表的主时基源。
- 计时、数据记录器、物联网节点和低功耗传感器终端。
- 需要长期稳定计时的工业与消费类电子产品。
四、选用与电路匹配建议
- 外部匹配电容：当采用对称电容 C1=C2 时，加载电容与外部电容的关系为 CL ≈ (C1·C2)/(C1+C2) + Cstray。若寄生电容（PCB、管脚）约 2–3 pF，则每侧C约为 8–10 pF。请基于实际 PCB 寄生电容测量并微调。
- 启动与稳定：由于 ESR 较高，若振荡启动困难可检查电容匹配、放大器增益及 MCU 的振荡器使能设置。
- 布线建议：晶体与 MCU 振荡器引脚间走线尽量短且对称，附近避免大电流、高速信号与开关电源噪声；地线应回流良好以降低干扰。
- 焊接工艺：支持回流焊，遵循厂家推荐的温度曲线以防晶体性能退化。
五、使用与可靠性注意事项
- 不要在封装上施加过大机械应力或弯曲，以免引起频率漂移或失效。
- 储存与返修时避免长时间暴露于高湿、高温环境，使用防静电防潮包装。
- 在高精度计时应用中建议进行温度补偿或软件校准以降低温度相关的频率偏移。
六、采购与替代方案
Q13FC13500002 适合需要 7 pF 负载、±20 ppm 常温精度与工业温度范围的应用。若需更高温度稳定性或不同负载电容，可参考爱普生或其他厂商的同类 32.768 kHz 系列，选型时注意 ESR、CL 与封装尺寸的匹配，以确保与目标 MCU/RTC 的兼容性。
如需进一步的引脚图、封装尺寸或热回流曲线等详细资料，可依据具体型号向供应商索取规格书以完成最终电路与生产验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
