0132M4-8.000F08DTNJL 产品概述

一、性能概述

0132M4-8.000F08DTNJL 为 HCI(杭晶)出品的一款贴片晶振,标准工作频率为 8.000 MHz,面向对频率精度与体积有要求的工业级与消费类应用。器件采用 SMD3225-4P 封装(3.2 mm × 2.5 mm,四引脚结构),在宽温范围内提供稳定的振荡参考,适合直接与 MCU、定时电路及频率合成器配套使用。

二、关键参数

  • 晶振类型:贴片晶振(SMD)
  • 频率:8.000 MHz
  • 常温频差(25°C):±10 ppm
  • 频率稳定度(整体):±20 ppm(含温度项)
  • 负载电容(CL):8 pF
  • 等效串联电阻(ESR):100 Ω(典型/上限)
  • 工作温度范围:-40 ℃ ~ +85 ℃(工业级)
  • 封装:SMD3225-4P
  • 品牌:HCI(杭晶)

以上参数决定了该晶振在中低频、对频率漂移及体积敏感的系统中有较好适配性。

三、典型应用场景

  • 8-bit / 32-bit MCU 时钟源(低功耗嵌入式设备)
  • 人机界面、计时/定时控制电路
  • 消费电子与便携仪表(要求小型化与稳定时基)
  • 物联网节点、传感器网关、通信模块的频率参考
  • 工业控制与测量设备(-40~+85 ℃的温度要求)

四、设计与选型建议

  • 负载电容匹配:器件标称 CL=8 pF。电路中常采用对称电容 C1、C2,使得 CL = (C1·C2)/(C1+C2) + Cstray。若 PCB 与管脚寄生电容(Cstray)约为 2–5 pF,可选 C1=C2 约 6–12 pF(常用 10 pF),以获得接近标称负载的振荡条件。建议在样机阶段对频率进行实测并微调负载电容值。
  • ESR 与启动特性:ESR=100 Ω 表明对驱动能力有一定要求;在使用片内晶体振荡器的 MCU 时,请参照 MCU 数据手册确认其能驱动该 ESR,否则考虑使用外部缓冲或驱动放大器电路。
  • 频率精度与温漂:常温±10 ppm、整体±20 ppm 适合大多数计时与通信用途;若系统对长期老化或更严格温度稳定性有更高要求,应考虑温补晶振(TCXO)或频率校准机制。
  • 电源与地:晶振附近保持良好地平面与干净电源,避免数字干扰耦合到谐振回路;合理布线以减小寄生电容和噪声注入。

五、封装与焊接注意

  • 尺寸为 SMD3225,建议按照厂商提供的推荐焊盘尺寸布局,确保对称放置并缩短引脚长度以降低寄生电容与振动影响。
  • 兼容标准无铅回流工艺。建议遵循厂商的焊接温度曲线和回流参数,避免过高峰值温度或超长保温时间。
  • 贴装与回流后建议进行频率测试,确认焊接应力及热循环对频率无异常影响。

六、存储、检验与可靠性

  • 存储环境应干燥、常温,避免长期高湿高温环境。若采用防潮包装,请在规定的时间内回流贴装。
  • 出厂会有频率测试与外观检验;建议用户在接收后对关键参数(频率、ESR、负载匹配)进行抽样验证,尤其用于大批量生产前的首件确认。
  • 该型号适合工业温度等级应用,但关键应用场合建议做 EMC、振动与温度循环测试以验证系统级可靠性。

总结:0132M4-8.000F08DTNJL 是一款小尺寸、工业温度范围内的 8 MHz 贴片晶振,适合对体积和频率稳定性有要求的嵌入式与工业应用。合理匹配负载电容、注意焊接工艺和驱动能力,是保证振荡性能的关键。

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.
