FL38T2-32.768-NTLLLDT 产品概述
一、产品简介
FL38T2-32.768-NTLLLDT 是 HCI（杭晶）推出的全国产化直插32.768kHz石英晶体（封装：DT-38，圆柱3×8，2P）。该器件专为低功耗实时时钟（RTC）与计时应用设计，具备稳定的频率特性和工业级工作温度范围，适用于绝大多数微控制器与手持设备时钟源需求。
二、主要技术参数
- 标称频率：32.768 kHz
- 常温频差（初始公差）：±20 ppm
- 频率稳定度（-40℃ ~ +85℃）：±20 ppm
- 负载电容：12.5 pF
- 等效串联电阻（ESR）：50 kΩ
- 工作温度范围：-40℃ ~ +85℃
- 封装形式：DT-38（圆柱 3×8，直插 2 引脚）
- 品牌：HCI（杭晶）
三、产品特性
- 高频率精度高：初始频差及温度稳定度均可达±20 ppm，满足多数精确计时需求。
- 低频耗、适配RTC：32.768kHz 为计时应用行业标准频率，兼容常见RTC及低功耗MCU振荡器。
- 宽温度范围：-40℃至+85℃，适合工业与消费类环境。
- 标准直插封装：DT-38 圆柱直插结构，便于手工插件与波峰/手工焊接装配（请注意安装与焊接工艺要求）。
四、安装与电路建议
- 晶体工作需配合外围电容以实现目标负载电容（12.5 pF）。在实际电路中，两侧并联电容值应考虑电路板走线与寄生电容，常见取值范围可在 18–33 pF 之间，实际应通过校准确定最优值。
- 建议将晶体靠近 MCU/RTC 的振荡引脚放置，减小引线与走线长度以降低寄生电容和干扰。
- 直插器件在机械固定与过度弯折引脚时应小心，避免损伤晶体体与引线焊接点。
五、典型应用
- 实时时钟（RTC）模块
- 便携式与可穿戴设备计时功能
- 工业控制与测量设备
- 低功耗物联网终端与传感器节点
- 家用电器与安防设备时间基准
六、可靠性与包装
该型号为国产化产品，适合批量供应与长期生产替代。出货前经常规电气性能与振荡测试，推荐在使用前进行进样验证以确认在目标系统中的稳定性。包装形式根据订单可提供散件或托盘装，便于生产线装配。
七、选型与订购建议
在选型时，请确认系统对频率公差、温度范围与负载电容的具体需求；若对频差或稳定度有更高要求，可咨询 HCI 提供更高等级的定制版本。订购时请注明型号 FL38T2-32.768-NTLLLDT、数量与包装要求，以便快速交付。

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.
