X49SD20MPB2SC 产品概述
一、产品简介
X49SD20MPB2SC 为 YXC（扬兴科技）出品的直插式晶振，封装为 HC-49S（直插型/HC-49US 同类规格），标称频率 20.000 MHz。该器件以稳定性和性价比为主，适用于要求中等精度与长期可靠时钟源的电子设备。
二、主要参数
- 晶振类型：直插晶振（HC-49S）
- 标称频率：20 MHz
- 常温频差（初始公差）：±10 ppm（室温校准）
- 负载电容：15 pF（CL）
- 频率稳定度（全温漂/长期）：±30 ppm
- 工作温度范围：-20 ℃ ~ +70 ℃
- 品牌：YXC 扬兴科技
三、应用场景
适合用作微控制器、串口通信、计时/时钟模块、仪表与消费类电子等对频率精度有一定要求但不需军工级温度范围或极端环境的应用。直插封装便于手工装配、样机验证与小批量生产。
四、使用建议
- 晶体与振荡器之间通常需配两只负载电容以匹配 CL；按照 CL=15 pF 与典型板上寄生电容 2~5 pF，建议使用约 22 pF 的并联电容（两个电容相等）作起振负载，最终参数以目标电路实际起振与频率偏差为准调整。
- 布局时应尽量缩短晶振引脚与 MCU 振荡脚之间的连线，避免数字信号线或大电流回路靠近以减小干扰。
- 直插件在波峰焊或回流焊场景需参考厂家推荐的最高焊接温度与时间，手工焊接时避免过热引起频率漂移或损伤。
五、可靠性与注意事项
- 常温初始频差±10 ppm 与全温频偏±30 ppm 反映该型号在一般商用温度范围内的稳定性；若应用需要更高精度或宽温范围（如 -40 ℃ 至 +85 ℃），建议选用对应等级的石英元件。
- 存放时避免潮湿、强酸碱及强振动环境；长期存储建议原包装防潮并避光。
- 不要超出制造商推荐的驱动电平与机械应力范围，避免因过驱或碰撞导致性能退化。
X49SD20MPB2SC 以其 20 MHz 的稳定输出、直插便捷的装配方式以及适中的频率精度，适合中小批量与样机开发中作为可靠的时钟源选择。若需更详尽的电气参数（等效串联电阻、驱动电平、引脚间距及焊接规范等），请参阅扬兴科技提供的产品数据表或联系供应商获取技术资料。

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.
