X49SD2712MSD2SC 产品概述
一、产品简介
X49SD2712MSD2SC 是扬兴科技（YXC）生产的一款直插式无源晶体振荡器（晶振），封装为经典 HC-49S 直插形式，标称频率 27.12 MHz。该器件为被动谐振元件，用于提供高精度时基或振荡参考，需要与外部振荡电路（如反相放大器或 MCU 内部振荡器电路）配合使用。
二、主要参数
- 类型：无源晶振（直插，HC-49S）
- 频率：27.12 MHz
- 常温频差：±20 ppm（出厂静态偏差）
- 负载电容：20 pF（额定 CL）
- 频率稳定度：±30 ppm（典型环境/温度范围内整体稳定度）
- 工作温度：-20 ℃ ～ +70 ℃
- 品牌：YXC 扬兴科技
三、产品特性与优势
- 高频率精度高：常温偏差仅 ±20 ppm，适合对频率精度有较高要求的短距离无线、遥控和通信应用。
- 良好的环境稳定性：整体频率稳定度 ±30 ppm，适应常见工业与民用温度范围。
- 直插 HC-49S 封装：便于手工焊接与波峰/回流前的插件工艺，适合小批量装配或维修更换。
- 被动元件：无源结构可靠、老化小，长期漂移可控。
四、典型接法与使用建议
- X49SD2712MSD2SC 为无源晶体，需与外部振荡器电路（如 Pierce 或 Colpitts 拓扑）配合。
- 负载电容 CL=20 pF，通常采用两只并联到地的电容构成等值负载。若采用两只相同电容，单只电容值一般按电路寄生电容（走线与管脚）调整，典型范围可在 30–47 pF 之间，具体以实际电路校准后确定。
- 布局建议：晶体尽量靠近振荡器输入端放置，减小走线长度与寄生电容，避免紧邻高频开关或大电流回路。
- 焊接：遵循 HC-49S 焊接工艺规范，避免长时间高温直接作用在晶体封装上以减小应力和漂移。
五、典型应用场景
- 27.12 MHz 频段的遥控器、玩具遥控、无线传输模块与接收端。
- 低功耗射频设备、短距离数据链路、无线感测器节点等需稳定频率参考的场合。
- 工业控制、测试仪器中作为精确时基或参考频率源。
六、可靠性与存储
- 存放时避免潮湿、高温与剧烈振动，推荐干燥环境保存。
- 芯片属于精密谐振器件，装配与测试时应注意防静电与机械应力，避免弯折引脚过度施力。
- 在重要设计中建议做温度漂移与长期老化测试，以验证在目标应用环境下的实际频率稳定性。
X49SD2712MSD2SC 以其稳定的频率特性和常见的直插封装，在需要可靠频率参考且便于手工装配或维修的应用中是一个实用的选择。若需更详细的封装尺寸、引脚间距或环境试验数据，请索取扬兴科技的产品规格书（Datasheet）。

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.
