FL26T2-32.000-NTLLLDTL 直插石英晶振产品概述

一、产品定位与核心特性

FL26T2-32.000-NTLLLDTL是杭晶电子(HCI)推出的工业级直插石英晶振,针对32kHz时钟需求场景设计,核心定位为“低成本、高精度、宽温稳定”的基础时钟源。其核心特性包括:

  1. 标准32kHz频率:适配绝大多数RTC、嵌入式系统的低速时钟需求;
  2. 直插DT-26封装:焊接便捷,兼容手工/自动化生产;
  3. 双20ppm精度:常温频差±20ppm,-40℃~+85℃宽温下频率稳定度仍达±20ppm;
  4. 12.5pF负载电容:适配常见电路设计,减少匹配成本。

二、关键性能参数深度解析

该晶振的性能参数覆盖“频率精度、环境适应性、负载匹配”三大核心维度,具体解析如下:

(1)频率基础参数

  • 标称频率:32.000kHz(工业标准计时频率,广泛用于RTC、MCU低速时钟);
  • 常温频差:±20ppm(即频率偏差≤640Hz,满足99%以上消费/工业计时场景的精度需求);
  • 频率稳定度:±20ppm(-40℃~+85℃全温区范围内,频率变化≤640Hz,避免极端温度下计时漂移)。

(2)负载与环境参数

  • 负载电容:12.5pF(电路中需并联匹配电容,若负载电容偏差±1pF,频率偏差约±5ppm,需注意匹配);
  • 工作温度范围:-40℃~+85℃(工业级温度标准,覆盖户外、车间等恶劣环境);
  • 存储温度范围:-55℃~+125℃(增强长期可靠性,适应仓储运输的温度波动)。

三、DT-26封装与机械规格

DT-26是HCI针对低频晶振设计的小型直插封装,机械规格适配紧凑PCB布局:

  • 引脚数量:2引脚(直插式,焊接简单);
  • 封装尺寸:约2.5mm(宽度)×6.0mm(长度)×3.0mm(高度)(参考行业标准,具体以HCI datasheet为准);
  • 引脚间距:2.54mm(标准DIP间距,兼容通用面包板、PCB焊盘);
  • 封装材质:塑料封装(抗冲击、耐老化,适合批量生产)。

四、典型应用场景

FL26T2-32.000-NTLLLDTL因32kHz的标准性与宽温稳定性,广泛应用于以下场景:

(1)实时时钟(RTC)模块

  • 适配DS1302、PCF8563、DS3231等RTC芯片,保证年计时误差≤5分钟(按±20ppm计算),满足日常计时需求;
  • 应用产品:智能手表、电子钟、智能家居控制中心。

(2)嵌入式系统低速时钟

  • 作为MCU(如STM32、ATmega系列)的LSE(低速外部晶振),替代内部RC振荡器,降低系统功耗(32kHz晶振功耗远低于高速晶振);
  • 应用产品:工业传感器节点、物联网终端、智能电表。

(3)消费电子计时单元

  • 计算器、电子日历、小型闹钟的核心计时组件,成本低且稳定性强;
  • 应用产品:学生计算器、桌面电子钟。

五、可靠性与选型注意事项

(1)可靠性保障

  • 出厂前经过24小时老化测试,筛选初期失效器件,保证长期稳定性;
  • 抗振动性能:符合IEC 60068-2-6标准(振动频率10~2000Hz,加速度1g),适合工业现场;
  • 抗冲击性能:符合IEC 60068-2-27标准(冲击加速度100g,持续时间6ms),运输/安装不易损坏。

(2)选型与使用注意

  1. 负载电容匹配:电路中需并联总电容为12.5pF的电容(可采用12pF固定电容+0.5pF微调电容,或两个6.2pF电容并联),避免频率偏移;
  2. 焊接规范:烙铁温度≤260℃,焊接时间≤3秒/引脚,避免热损伤晶振内部石英片;
  3. 引脚处理:避免引脚过度弯曲(弯曲半径≥1mm),焊接后用酒精清洁助焊剂残留;
  4. 替代选型:若需更高精度(±10ppm),可选择HCI同系列高精度版本;若负载电容为10pF,需更换适配型号。

六、总结

FL26T2-32.000-NTLLLDTL作为HCI杭晶的经典直插晶振,以32kHz标准频率、±20ppm宽温精度、DT-26易焊封装为核心优势,覆盖从消费电子到工业控制的多场景需求。其低成本、高可靠性的特点,使其成为32kHz时钟设计的优先选型之一。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
