CSA0603X5R105K500JT 产品概述

一、主要参数概述

CSA0603X5R105K500JT 是 HRE(芯声) 推出的一款贴片多层陶瓷电容,主要参数如下:容值 1.0 µF,公差 ±10%(K),额定电压 50 V,介质为 X5R,封装 0603(1608 英制)。该型号适用于对容量要求较高、体积受限且成本敏感的通用旁路/去耦和耦合场合。

二、介质与温度特性

X5R 属于 Class II 高介电常数材料,其特点是介电常数高、单位体积容量大,但温度稳定性和线性较 Class I 差。X5R 标准工作温度范围为 -55°C 至 +85°C(有时扩展至 +125°C),在该温度范围内电容量变化通常控制在 ±15% 以内。需要注意的是 X5R 对直流偏压和温度敏感,在高偏压或低温下电容量会出现可观的下降,应在设计时予以考虑。

三、主要性能与应用场景

  • 体积优势:0603 封装适用于空间受限的移动设备、通信设备和工控模块。
  • 高频性能:多层陶瓷结构具有较低等效串联电阻(ESR)和等效串联电感(ESL),适合高频旁路与去耦。
  • 容量密度高:1 µF 在 0603 中属常见容量,适合电源去耦、滤波、耦合等用途,但对高精度时间基准或高线性要求电路不推荐。 典型应用:移动通讯设备、电脑与外设电源去耦、基站与网络设备的旁路电容、家用电器与照明的滤波回路,以及汽车电子的辅助系统(需按汽车级可靠性评估选型)。

四、选型与使用建议

  • 直流偏压考虑:X5R 在高电压环境下会发生容量下降,建议在关键去耦场合进行实际电压下的容量测量或通过并联多个器件提高有效容量。
  • 温度与老化:X5R 存在一定的温漂与电容老化效应(随时间轻微递减),若电路对容量稳定性要求高,优先考虑 C0G/NP0 或更高等级的陶瓷。
  • 焊接工艺:适用于常规回流焊工艺,推荐遵循供应商的回流温度曲线与预热/冷却规范以避免机械应力导致裂纹。
  • 尺寸与可靠性:0603 尺寸在受热、贴装应力下对裂纹敏感,建议 PCB 设计上减缓焊盘不对称及热位移,并在关键应用中做可靠性测试。

五、封装与可获取信息

封装 0603 带来装配灵活性与高密度布局优势。型号中的“105”表示 1.0 µF,后缀 K 表示 ±10% 公差。HRE(芯声) 提供的该型号在常见出货包装和批量可追溯性上可满足一般电子制造需求,建议在批量使用前向厂商索取详尽规格书、典型性能曲线(温度特性、直流偏压曲线、ESR/ESL)与可靠性测试报告。

六、典型工程注意事项

  • 在高压、低温或高可靠性场合,先做样机验证直流偏压下的有效容量和温度漂移。
  • 对于电源去耦,可通过并联不同封装和不同容量的电容组合,平衡低频和高频滤波效果。
  • 汽车或工业级应用若涉及严苛环境,应咨询供应商是否有 AEC‑Q200 或相应认证的同款产品。

总体而言,CSA0603X5R105K500JT 以其高容量密度与通用性,适合多数去耦、旁路与耦合场景,但在涉及高稳定性或高偏压应用时需注意 X5R 的固有特性并在设计中予以补偿。

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
