FS55X685K101EHG 产品概述

一、产品简介

FS55X685K101EHG 为 PSA(信昌电陶)系列的高电压贴片多层陶瓷电容(MLCC),标称容量 6.8 µF,公差 ±10%,额定电压 100 V,介质类型 X7R,封装规格 2220(大尺寸贴片)。该型号针对需要较大容值与较高工作电压的电源与模拟电路应用而设计,兼顾体积效率与电气性能。

二、主要电气特性

  • 容值:6.8 µF ±10%(标称值,实际使用时受温度/偏压影响)。
  • 额定电压:100 V DC(请注意在高偏压下容值会下降,应按应用做 DC-bias 测试)。
  • 温度特性:X7R,工作温度范围典型为 -55°C 至 +125°C,介质随温度变化一般在 ±15% 范围内。
  • ESR/ESL:MLCC 本身 ESR 很低、ESL 也较小,适合高频去耦与滤波,但对于大能量储存或高纹波电流场合需参考厂商的纹波能力规范。
  • 老化与偏压效应:Class II 陶瓷存在随时间(老化)与直流偏压导致的容值下降,设计时应留有裕量或并联多只以达到稳定需求。

三、典型应用场景

  • 开关电源输入/输出滤波、DC-link(在满足 DC-bias 和纹波限制的前提下)。
  • 高压电源去耦与旁路,模拟信号链电容耦合/滤波。
  • 电源瞬态储能与突发电流补偿。
  • 高频电路中的旁路与谐振网络(注意容值与频率特性)。

四、选型与使用建议

  1. DC-bias 考虑:6.8 µF 在 100 V 标称下,实际在高电压偏压时可出现显著容值下降。建议在设计阶段参考厂家提供的 DC-bias 曲线或在实际工作电压下做测量,必要时选择更大标称容量或并联多个器件。
  2. 温度与频率:X7R 在宽温度范围内保持较好稳定性,但高温下容值仍有变化。高频滤波场合注意容抗随频率变化。
  3. 机械应力管理:2220 为较大体积 MLCC,易受 PCB 弯曲和热应力导致裂纹,布局时避免放置在板边缘或机械受力点;可考虑在焊盘设计上使用沉孔/圆角和均匀锡膏量以降低应力集中。
  4. 并联与替代:若需更高稳定性或更大能量储备,可并联多个 MLCC,或结合薄膜/铝电解电容以获得更好的低频能量储存与纹波处理。

五、焊接、储存与可靠性注意事项

  • 焊接工艺:遵循无铅回流焊温度曲线与厂家资料,避免骤冷骤热及过猛的加热速率以防晶片开裂。
  • 湿敏与烘烤:按厂家湿敏等级(MSL)进行储运与回流前烘烤处理,长期暴露空气中可能吸潮,影响回流时可靠性。
  • 贴装工艺:推荐使用适配 2220 的贴片模板与焊盘设计,适当控制锡膏印刷量,避免焊接后应力集中。
  • 可靠性试验:在关键应用建议进行热循环、振动与长时偏置测试验证,特别是高压与高温工作条件下。

六、包装与合规

FS55X685K101EHG 常见为卷带(tape-and-reel)包装,适合表面贴装自动化生产。通常支持无铅回流焊工艺并符合工业品的常见环保标准(具体合规与检测报告请以厂家资料为准)。

总结:FS55X685K101EHG 在需要较大容量且较高电压的贴片场景中具有体积效率高、ESR 低的优势,但设计时必须重视 DC-bias、温漂与机械应力等特性,结合实际测量与可靠性验证以保证长期稳定运行。若需更详细的电气、机械尺寸或 DC-bias 曲线,请参考 PSA(信昌电陶)提供的完整数据手册。

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
