TAXD13.52127M2GDDBET2S是雅晶鑫(YJX) 推出的一款直插式无源晶振,采用行业通用的HC-49S封装,属于低成本、高可靠性的时钟参考元件。该型号针对13.52127MHz特定频率优化,适配多种需要精准时钟信号的电子设计场景,尤其适合传统插件工艺的电路开发。
晶振核心参数直接决定应用适配性,以下是该型号关键参数及实际意义:
该频率接近13.56MHz(ISM频段常用频率),广泛应用于高频RFID、蓝牙辅助时钟、小型通信模块等场景,是消费电子与工业控制中常见的时钟基准频率。
频差指常温(25℃左右)下实际输出频率与标称频率的偏差,ppm为“百万分之一”。计算可得:
偏差范围 = 13.52127MHz × 20×10⁻⁶ ≈ ±270Hz
该精度可满足大多数单片机、电子钟、小型传感器节点的时钟需求,无需额外温补电路。
无源晶振需外接两个负载电容(晶振两端各接一个到地),电容值需与标称负载电容匹配。若不匹配,实际输出频率会偏离标称值,设计时需严格选用10pF电容(误差≤5%即可)。
指工作温度范围内(-20℃~+70℃) 的频率最大变化量,反映晶振抗温度干扰能力。该参数下,温度变化导致的频率偏差≈±406Hz,可稳定适配室内环境、一般工业常温场景(无需宽温要求)。
ESR是晶振内部等效电阻,值越低越易起振。40Ω属于中等偏优范围,可保障晶振在大多数电路中快速起振,避免“不起振”“停振”问题。
覆盖工业级常温范围,适用于室内电子设备、小型工业控制器、消费电子产品等,不建议在极端低温(<-20℃)或高温(>+70℃)环境下使用。
该晶振采用HC-49S直插封装,具体物理特性如下:
直插封装优势在于易焊接、易维护——无需SMT贴装设备,降低生产门槛;若出现故障,可直接替换,维修成本低。
综上,TAXD13.52127M2GDDBET2S是一款高性价比、易使用的直插无源晶振,适配多种需要13.52127MHz时钟的电子设计,尤其适合传统插件工艺的项目开发。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
