FS55X156K101EGG 产品概述 — PSA (信昌电陶) 15µF ±10% 100V X7R 贴片电容(2220)

一、产品简介

FS55X156K101EGG 为 PSA(信昌电陶)出品的一款多层陶瓷贴片电容(MLCC),封装规格为 2220(EIA 2220),标称电容 15µF,公差 ±10%,额定直流电压 100V,介质温度特性为 X7R。该器件在体积与电容量之间取得平衡,适用于需中高电压与较大电容量的贴片应用场合。

二、主要参数

  • 电容:15 µF
  • 公差:±10%
  • 额定电压:100 V DC
  • 温度特性:X7R(-55°C 到 +125°C,典型容值变化 ≤ ±15%)
  • 封装:2220(适配自动贴装)
  • 品牌:PSA(信昌电陶),型号 FS55X156K101EGG

三、产品特点

  • 高容值:在 2220 尺寸下实现 15µF,体积利用率高。
  • 稳定性:X7R 介质在宽温区间内提供相对稳定的电容特性,适合一般电源滤波与储能用途。
  • 低等效串联电阻(ESR)及寄生电感(ESL),适合高频去耦与快速电流脉冲场合。
  • 适配自动化生产:常规卷带(tape & reel)包装,便于高速贴装与回流焊工艺。

四、典型应用

  • 开关电源输入/输出滤波与储能
  • DC-DC 转换器与功率模块缓冲电容
  • 工业电源、通讯电源与测试设备的去耦和旁路
  • 需要中高压支持的功率电子和控制类电路

五、设计注意事项与建议

  • DC 偏压效应:X7R 型 MLCC 在直流偏压下会出现显著的容量降低,尤其高容值器件更明显。实际设计中请以实测在工作电压下的有效容量为准,并预留裕量。
  • 温度特性:X7R 在 -55°C~+125°C 范围内总容差可达 ±15%,在极端温度下应考虑容值漂移对电路的影响。
  • 焊接工艺:建议遵循厂家/IPC-JEDEC 的回流焊规范进行焊接,避免长期过高回流温度或多次高温循环,以减少裂纹风险。
  • 机械应力:贴片电容对 PCB 弯曲和热机械应力敏感,布板时避免靠近板边或在高应力区域固定,应保证良好焊点,必要时采用粘胶固定。

六、可靠性与质量控制

  • X7R 为 II 类铁电陶瓷,存在陶瓷老化效应(随时间缓慢下降),可通过退火处理部分恢复;长期可靠性应通过温度循环、湿热与电压应力测试验证。
  • 推荐在产品开发阶段进行 DC 偏压、温度循环、振动与机械冲击等加速试验,评估实际应用中的性能稳定性。

七、包装与订购

FS55X156K101EGG 通常以卷带(tape & reel)形式供货,适用于自动贴装生产线。订购时请与供应商确认最小包装数量、交期及是否提供电性能在工作电压下的测量数据(DC bias 曲线),以便在设计中做精确评估。

总结:FS55X156K101EGG 在 2220 尺寸下提供较大电容量和较高额定电压,适合需要中高压滤波与缓冲的应用场合。选型时务必考虑 DC 偏压与温度漂移对有效电容的影响,并配合相应的可靠性验证与合理的电气/机械布局。若需更详细的电气特性曲线(DC bias、频率响应、耐压与寿命测试数据),建议索取厂家规格书与样品验证。

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
