TAXM32768K2BGDAZN2T 产品概述
一、产品简介
TAXM32768K2BGDAZN2T 是雅晶鑫（YJX）出品的贴片型32.768kHz石英晶振，封装型号为 DT-26（贴片圆柱蛙腿 2×6）。该器件为低频时钟源，专为实时时钟（RTC）与低功耗计时电路设计，具有稳定的频率输出与便于 SMT 装配的封装形式。
二、主要参数
- 标称频率：32.768 kHz
- 常温频差：±20 ppm（常温）
- 频率稳定度：±20 ppm
- 负载电容：12.5 pF
- 等效串联电阻（ESR）：50 kΩ
- 工作温度范围：-20 ℃ 至 +70 ℃
- 封装：DT-26（贴片圆柱，蛙腿引脚，尺寸 2×6）
- 品牌：YJX（雅晶鑫）
三、产品特性
- 高频率精度高，常温下±20 ppm，适合对时钟精度有较高要求的 RTC 应用；
- 低频低功耗，ESR 值适中，便于与典型微控制器内部负载网络匹配；
- 封装紧凑、引脚形式利于表面贴装与自动化焊接，适合大批量生产。
四、典型应用
- 晶振作为微控制器与实时时钟（RTC）的时间基准；
- 可穿戴设备、手持终端、家电、物联网节点等需要长期稳定计时与低功耗的场景；
- 计时模块、数据记录器与低速通信系统。
五、设计与焊接建议
- 晶振两引脚分别接至 MCU 的 XTAL/OSC 两端，配合外部负载电容实现所需加载（负载电容标称 12.5 pF，总等效值需考虑走线与封装寄生电容）；
- 建议在电路板布局时将晶振尽量靠近 MCU，缩短引线并避开高速信号线与强干扰源；
- 装配时优先采用推荐的回流工艺或手工焊接规范，避免机械应力和过度加热，确保焊接可靠性。
六、选型与注意事项
- 若工作温度或频率稳定度需求超出 -20~+70℃ 或 ±20 ppm，应选择更高等级的器件；
- 在设计负载电容时，应根据实际电路板寄生电容（典型 2–5 pF）调整每侧电容值以保证最终负载为 12.5 pF；
- 关注 ESR 与目标振荡器电路的启动能力，必要时验证启动时间与稳定时间。
七、包装与订购
- 型号：TAXM32768K2BGDAZN2T；品牌：YJX（雅晶鑫）；封装：DT-26（贴片圆柱蛙腿 2×6）。

Request for quote
Send RFQ
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.
