0132M4-8.000F20DTNLL 产品概述

一、产品简介

0132M4-8.000F20DTNLL 是杭晶(HCI)推出的一款国产化贴片晶振,工作频率为 8.000 MHz,采用 SMD 3225-4P 贴片封装(3.2 × 2.5 mm,4 引脚金属盖结构)。该器件为基频工作晶振,面向需可靠时钟源的单片机、计量、电力、通信及物联网等电子设备,具备工业级工作温度范围与较高频率稳定性,适合批量贴装与回流焊工艺。

二、主要技术参数

  • 型号:0132M4-8.000F20DTNLL
  • 品牌:HCI(杭晶)
  • 晶振类型:贴片晶振(SMD,金属封装)
  • 封装:SMD3225-4P(3225,4 引脚)
  • 频率:8.000 MHz
  • 常温频差(Initial Accuracy @ 25°C):±10 ppm
  • 频率稳定度(含温度影响、其它环境因素):±20 ppm
  • 额定负载电容(CL):20 pF
  • 等效串联电阻(ESR):100 Ω(典型/最大)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 全国产化,适合国产供应链替代与本地化生产需求

三、性能特点与优势

  • 国产化供应:本产品为全国产化制造,供应链稳定,便于量产与长期采购。
  • 小型化、贴片化:3225 小尺寸封装(3.2 × 2.5 mm),适合高密度 PCB 布局与自动化贴装。
  • 金属封装:金属盖提升机械与环境保护,利于长期稳定性与可靠性。
  • 工业温度等级:-40 ℃ 至 +85 ℃,适用于多数工业与商业应用场景。
  • 良好频率精度与稳定性:常温频差 ±10 ppm,综合稳定度 ±20 ppm,满足大多数 MCU 时钟与通信定时需求。
  • 通用负载电容 20 pF:适配常见晶振电路设计。

四、典型应用场景

  • 单片机(MCU)系统的主时钟或外部晶振
  • 实时时钟(RTC)和计时/计数模块(对频差要求较高的场合)
  • 工业控制、仪表、楼宇自动化设备
  • 通信网关、无线模块、物联网终端(对温度范围与稳定性有要求)
  • 消费电子与测试设备(需要贴片化、回流兼容的晶振方案)

五、电气与电路注意事项

  • 负载电容匹配:晶振标称 CL = 20 pF。实际 PCB 上需要外接 C1、C2 两个电容与地形成对称两端负载。近似计算:
    • CL ≈ (C1 × C2) / (C1 + C2) + Cstray(Cstray 为线路寄生电容,一般 2–5 pF)
    • 若 Cstray ≈ 3 pF,则可取 C1 = C2 ≈ 2 × (CL - Cstray) ≈ 34 pF,通常可采用 33 pF 标准值并进行实测微调。
  • ESR(100 Ω)与驱动能力:等效串联电阻较大时,晶体需要电路(如 MCU 内部振荡器)具备足够的驱动能力。设计中应确认振荡器电路的负载/驱动范围与晶体 ESR 匹配,避免起振困难或起振时间过长。
  • 布局要求:晶振与 MCU(或振荡器输入)应尽量靠近布置,两引脚走线短且对称,减少寄生电容与干扰。地线须良好回流,避免在晶体附近布置高速或大电流走线。
  • 焊接与回流工艺:兼容标准回流焊。建议在回流曲线、温度剖面下验证实际焊接工艺,避免过热导致频率漂移或封装损伤。

六、可靠性与包装

  • 本器件采用金属封装,耐机械振动与冲击性能良好。出厂经过电气参数测试与筛选,适于批量贴装。
  • 建议在相对湿度与 ESD 控制良好的环境中进行贴装与储存;若长期储存,应遵循厂方提供的干燥/防潮措施(必要时回流前采用烘烤处理以消除吸湿风险)。

七、选型建议与检验要点

  • 确认目标系统对频率精度、温漂与 ESR 的要求,若系统对频率稳定性要求更高,可选择更高等级稳定度的晶振或补偿方案。
  • 在设计评估阶段进行实样测试:起振性能、稳定性、频率漂移与温度循环测试。
  • 若需要更宽温度范围或更低 ESR、不同负载电容或封装形式,可与供应商沟通定制或替代型号。

八、订购信息

  • 型号全称:0132M4-8.000F20DTNLL
  • 品牌:HCI(杭晶)
  • 封装:SMD3225-4P
  • 如需批量采购、样品或技术资料(封装图、焊盘建议、频率-温度曲线等),请联系杭晶官方或授权分销商获取详细数据手册与出货说明。

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.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
