TAXD32768K2BRDAKT2S 直插石英晶振产品概述
一、产品定位与核心属性
TAXD32768K2BRDAKT2S是雅晶鑫（YJX）推出的32.768kHz直插石英晶振，属于通用计时类频率元件，核心面向需要精准低频计时、低功耗电路的应用场景。该产品以稳定的频率输出、适配常规电路的参数设计为核心，满足商用级设备的计时精度需求，是电子钟表、MCU实时时钟等场景的高性价比选择。
二、基础技术参数详解
该晶振的关键技术参数直接决定应用适配性，核心参数如下：
- 标准频率：32.768kHz，此频率为2¹⁵Hz，天然适配数字分频电路（15级分频可得到1Hz精准时钟），是计时类电路的通用基准频率；
- 常温频差：±20ppm，即常温（25℃左右）下频率偏差不超过32.768kHz×20×10⁻⁶≈0.655Hz，精度满足日常计时设备需求；
- 负载电容：6pF，是振荡电路匹配的核心参数，需与外围杂散电容、负载电容总和匹配（电路设计需预留余量）；
- 频率稳定度：±30ppm，包含温度变化、电源波动等因素的总偏差，确保在-10℃~+60℃温区内保持计时精度；
- 等效串联电阻（ESR）：40kΩ，处于商用32.768kHz晶振的合理范围，保证振荡电路稳定启动与输出；
- 工作温度范围：-10℃~+60℃，覆盖常规室内外商用场景（家庭、办公室、一般工业环境）。
三、封装与物理特性
TAXD32768K2BRDAKT2S采用DT-26标准直插封装，特点如下：
- 2引脚直插设计，引脚间距符合行业标准，适配通孔焊接工艺，安装便捷；
- 封装尺寸紧凑（典型φ2mm×6mm，具体以厂商规格书为准），适合小型化计时设备的空间布局；
- 封装材料采用耐高温、抗干扰的塑料/陶瓷（依工艺），有效保护内部石英晶片，降低环境干扰。
四、典型应用场景
基于低频精准、低功耗适配的特性，该晶振主要应用于：
- 电子计时设备：石英钟、闹钟、电子日历等日常计时产品，提供精准时间基准；
- MCU实时时钟（RTC）模块：嵌入式系统中作为RTC时钟源，实现断电计时、定时唤醒；
- 低功耗嵌入式系统：智能手环、电子秤、小型传感器节点等，适配系统低功耗需求；
- 小型电子设备：计时器、定时器、电子玩具等简单计时类产品。
五、可靠性与应用优势
该产品的可靠性与优势体现在：
- 频率稳定性可靠：±30ppm稳定度在商用温区内表现稳定，避免温度变化导致计时偏差；
- 成本效益高：直插封装工艺成熟，成本低于高端贴片晶振，适合量产计时设备；
- 适配性强：32.768kHz为行业通用频率，6pF负载电容匹配大多数MCU的RTC电路，无需复杂匹配；
- 品牌保障：雅晶鑫（YJX）作为专业晶振厂商，产品符合电子行业标准，可稳定批量供货。
该晶振通过平衡精度、成本与可靠性，成为商用计时类设备的实用选择，可满足多数常规低频计时场景的需求。

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.
