FH20X103K302EGG 产品概述

一、产品简介

FH20X103K302EGG 是 PSA(信昌电陶)出品的一款安规型抑制电容,规格为 10nF(103),公差 ±10%,标称交流耐压 250VAC,防护等级为 X2,封装为 2220(SMD),工作温度范围 -55℃ 至 +125℃。该器件专为电源输入端的差模干扰抑制和跨线(L–N)抑制设计,适合工业与民用电源滤波、EMI 抑制与浪涌吸收等应用场景。

二、主要技术参数

  • 容值:10 nF(标称)
  • 精度:±10%
  • 额定工作电压(AC):250 VAC
  • 防护等级:X2(跨线型安全电容)
  • 工作温度:-55℃ ~ +125℃
  • 封装:2220(适用于表面贴装工艺)
  • 品牌:PSA(信昌电陶)

三、产品特点

  • 针对交流电网设计:X2 等级表明该电容可安全用于电源线对电源线(L–N)之间,能够在正常工作条件下有效抑制差模干扰,降低对后级电路的干扰风险。
  • 稳定性好:容值随温度与频率变化较小,适合长期工作在工业环境下的滤波和耦合用途。
  • 低损耗:设计上强调低等效串联电阻(ESR)与低损耗角,能够在工作频段内提供较好的抑制效果且发热小。
  • 宽温度范围:-55℃ ~ +125℃ 的额定温度范围适应严苛环境下的应用需求。
  • SMD 封装:2220 封装便于自动化贴装与回流焊工艺,适合大批量生产的装配线。

四、典型应用场景

  • 开关电源输入端差模干扰抑制(L–N)
  • 家电、照明、音视频等民用电器的 EMI 滤波
  • 工业设备电源滤波、抑制瞬态干扰
  • 电源适配器、逆变器等有较高电磁兼容要求的场合
  • 配合共模电感、Y 电容组成 EMI 滤波网络

五、使用与安装建议

  • 正确位置:X2 电容专用于线路对线路(L–N)抑制,不宜替代 Y(线路对地)电容使用,以免安全风险。
  • 焊接工艺:采用符合厂家推荐的回流焊曲线进行焊接;高温短时回流会影响电容内部结构及可靠性,请避免超温或超时重流。
  • 环境与电压应力:即便额定为 250VAC,建议在设计中适当留有裕量(考虑工况可能出现的瞬态过压、线路波动与温升),并按必要的电气保护措施(限流、浪涌抑制)组合使用。
  • 布局注意:在 PCB 布局时,尽量缩短电容与电源输入端之间的走线,减少寄生电感;并注意与高压/高热元件保持安全间距,满足爬电距离与对外壳接地要求。

六、可靠性与安全性

  • X2 等级说明:该器件设计用于跨线抑制,具备一定的自我保护能力与故障容错特性(在规定的工作条件下出现内部失效时不应造成危险性放电或火灾)。这类电容通常符合相关安全标准的设计要求(在产品选型时仍建议确认具体认证与测试报告)。
  • 温度与寿命:在 +125℃ 长期工作下会缩短器件寿命,建议在高温工况下对散热与电压应力进行评估与降额使用,以延长使用寿命与稳定性。

七、封装与订购信息

  • 封装形式:2220 表面贴装(SMD),适配自动贴片与回流焊流程,便于批量生产。
  • 型号说明:FH20X103K302EGG 对应 10nF、±10%、X2、250VAC 的规格;具体包装、卷带/盘数与交期请以 PSA(信昌电陶)正式报价单与现货信息为准。
  • 采购建议:在批量采购前,建议索取样品并在目标应用中进行必要的温升、耐压、老化与 EMI 性能验证,确认与系统其他元件的兼容性。

如需更详细的电气特性曲线(如频率响应、损耗因数 vs. 温度、冲击耐受试验数据)或相关安全认证资料(例如 IEC/EN 相关测试报告),可以联系供应商或索取器件的技术规格书(datasheet)以便进行深入验证。

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
