X49SD147456MSD2SC 产品概述
一、产品简介
X49SD147456MSD2SC 是 YXC（扬兴科技）出品的直插式无源晶振，标称频率 14.7456MHz，采用经典 HC-49S 封装，适用于对串口波特率、定时和频率基准有严格要求的电子设备。该型号以稳定的频率特性和通用的直插封装，便于在开发板、控制器和工业设备中替换与调试。
二、主要规格参数
- 类型：无源晶振（需外部振荡器电路）
- 频率：14.7456 MHz
- 常温频差（初始容差）：±20 ppm
- 负载电容（CL）：20 pF
- 频率稳定度（含温度影响）：±30 ppm（工作温度范围内）
- 工作温度：-20 ℃ ～ +70 ℃
- 封装：HC-49S（直插）
三、功能与特性
- 精确频率：14.7456MHz 是常见的串口系统频率源，能整除多种标准波特率（如 115200、57600 等），有利于减少 UART 通信误差。
- 高精度与稳定性：常温±20ppm 初始偏差与±30ppm 的温度稳定度，满足大多数工业与消费级通信与定时应用。
- 直插封装：HC-49S 直插形式便于手工焊接、维修和原型验证，兼容传统 PCB 布局与插装工艺。
- 无源器件：需配合 MCU 内部或外部放大器/反相器构成振荡电路，灵活性高。
四、典型应用场景
- 串口通信设备、调制解调器、工业控制器、仪表仪器等需要精确 UART 波特率的场合。
- 嵌入式系统开发平台、单片机时钟源、测试与测量设备。
- 需要稳定中频参考的各类电子模块与子系统。
五、使用建议与注意事项
- 振荡器电路：常用 Pierce 型振荡器需在晶体两端并联接地两个电容，以实现目标 CL=20pF。计算时考虑 PCB 引线与封装寄生电容（Cstray），常采用相等的两只电容，参考公式 CL ≈ (C1·C2)/(C1+C2) + Cstray。
- 焊接与安装：HC-49S 为直插元件，避免长期高温曝露，推荐遵循厂方焊接曲线和焊接时长限制以防损伤晶体。
- 环境与存储：避免强振动、冲击与潮湿环境，建议存放在干燥、常温条件下并防静电保护。
- 调试要点：振荡启动时间、负载电容选择和 PCB 布线（缩短引线、减小寄生电容与噪声耦合）对频率稳定性与可靠启动至关重要。
六、质量与售后
X49SD147456MSD2SC 采用成熟制造流程与测试流程，适合批量生产与工程验证。建议在设计阶段与供应商确认整机环境、振荡电路兼容性与焊接条件，以获得最佳性能与可靠性。若需资料（频率-温度曲线、等效电路参数、焊接规范等），请联系 YXC 扬兴科技 获取完整数据手册。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
