HCI 049SS2-8.000F18DTLJL 贴片石英晶振产品概述

一、产品定位与核心设计方向

该型号为杭晶(HCI)推出的工业级贴片石英晶振,针对中精度、宽温域、高可靠性的嵌入式系统需求定制,采用HC-49S-SMD标准贴片封装,核心频率8MHz,兼顾性能与成本控制,是工业控制、通信模块等场景的主流时钟源方案。

二、关键性能参数深度解析

1. 频率与精度指标

  • 标称频率:8MHz(石英晶振常用基准频率,适配90%以上MCU、DSP的时钟输入范围,无需额外分频/倍频);
  • 常温频差:±20ppm(25℃环境下,频率偏差≤8MHz×20×10⁻⁶=160Hz,满足常规工业控制、消费电子的时钟精度要求);
  • 全温频率稳定度:±30ppm(覆盖-40℃~+85℃工作温度,频率偏差≤240Hz,符合工业级设备宽温稳定性需求,避免极端温度下时钟漂移)。

2. 负载与阻抗特性

  • 推荐负载电容:18pF(晶振工作时需匹配外部18pF电容,需注意PCB布线寄生电容的补偿,避免实际负载偏差导致频率偏移);
  • 等效串联电阻(ESR):60Ω(同类8MHz贴片晶振中属于较低水平,ESR越低则晶振启动速度越快、功耗越低、抗电磁干扰能力越强)。

3. 环境适应性

  • 工作温度范围:-40℃~+85℃(工业级温度标准,可稳定工作于严寒户外、高温车间等场景,适配车载电子、户外传感器等设备)。

三、封装规格与物理特征

采用HC-49S-SMD贴片封装,符合国际标准小型化结构(具体尺寸参考HCI官方 datasheet,通常为5.0×3.2mm左右),支持自动化SMT贴装工艺,无需手工焊接,大幅提升生产效率;封装材质采用耐高温陶瓷+塑料组合,兼具绝缘性与抗机械冲击能力,适合批量工业生产场景。

四、典型应用场景

该型号因性能均衡、成本可控,广泛应用于以下领域:

  1. 工业控制设备:PLC可编程逻辑控制器、伺服驱动器、工业传感器模块的时钟基准;
  2. 通信与物联网模块:蓝牙低功耗(BLE)模块、WiFi模块、LoRa网关的辅助时钟;
  3. 消费电子:智能家电(空调、洗衣机控制器)、可穿戴设备(智能手环)的MCU时钟源;
  4. 车载电子:车载信息娱乐系统、胎压监测模块(TPMS)的辅助时钟(部分场景需结合整车级认证)。

五、可靠性与质量保障

杭晶(HCI)作为国内晶振行业知名厂商,该型号通过以下质量管控:

  • 生产工艺:采用高精度石英晶体切割、真空封装技术,每批次进行全温性能测试;
  • 合规认证:满足GB/T 14860-2013《石英晶体谐振器》标准,部分批次通过RoHS环保认证;
  • 寿命预期:典型工作寿命≥10万小时,可满足工业设备长期稳定运行需求。

六、选型与使用注意事项

  1. 负载电容匹配:需在晶振引脚与MCU时钟输入引脚间并联18pF陶瓷电容(若PCB寄生电容≥2pF,可适当减小外部电容至16pF);
  2. 布线要求:时钟线应尽量短(≤10cm)、远离电源/高频信号线,避免串扰导致频率不稳定;
  3. 焊接温度:SMT焊接峰值温度≤260℃,焊接时间≤10秒,避免高温损坏晶振内部石英晶体。

该型号凭借稳定的性能、工业级可靠性与亲民的成本,成为中低端嵌入式系统时钟源的优选方案,适配多数量产化电子设备的需求。

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.

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
