CSA0603X7R333K500JT 产品概述

一、产品简介

CSA0603X7R333K500JT 是 HRE(芯声)推出的一款贴片多层陶瓷电容(MLCC),规格为 33nF,精度 ±10%,额定电压 50V,介质类型 X7R,封装为 0603(约 1.6 × 0.8 mm)。该型号适用于对体积与成本敏感且需中等电容稳定性的各类电子产品中,兼顾封装微型化与可靠性,常见于电源旁路、耦合/去耦以及滤波电路。

二、主要电气参数

  • 容值:33nF(0.033µF)
  • 精度:±10%(K)
  • 额定电压:50V DC
  • 介质:X7R(温度特性:-55°C ~ +125°C,容值在该温区内变化受控)
  • 封装:0603(SMD,适合高速贴装生产线)
  • 品牌:HRE(芯声)

三、X7R 介质特点与电容稳定性

X7R 为常用的高介电常数陶瓷体系,特点是在宽温区间内保持较好的电容容量与体积效率。与 NP0/C0G 相比,X7R 的温度稳定性和线性度较差,但能在小尺寸下实现更大容量。需注意:

  • 温度特性:在 -55°C 至 +125°C 内容量变化受控,但并非线性;
  • 直流偏置效应:在接近额定电压时会出现一定的容量降低,具体下降量与尺寸和制造工艺相关,设计时应预留裕量;
  • 老化特性:陶瓷电容存在随时间缓慢衰减的现象(老化),首次电加热处理或长期储存会影响实际容值。

四、典型应用场景

  • 开关电源的输入/输出去耦与旁路;
  • 数字电路与微处理器电源稳压旁路;
  • 高频滤波与 EMI 抑制(配合其他元件使用);
  • 信号耦合/去耦(对精度和温漂要求不极端的模拟电路);
  • 移动设备、消费电子、工业控制与物联网终端等空间受限的应用。

五、封装与 PCB 使用注意事项

  • 0603 小尺寸有利于高密度布板,但焊盘设计需匹配制造商推荐尺寸以保证焊接质量与可靠性;
  • 贴片机与回流焊流程需按照 HRE 的回流曲线执行,避免过高峰值温度和过长保温时间;
  • 对于需高稳定性的关键回路,建议在设计时考虑电压降额与多并联电容组合(如与 NP0/C0G 并联以改善高频特性);
  • 在 PCB 布局中,电源去耦电容应尽量靠近电源引脚布置,缩短走线长度以降低 ESL/ESR 带来的影响。

六、可靠性与品质控制

HRE(芯声)系列 MLCC 通常经过 100% 电气测试与可靠性验证,产品应符合相关工业标准(如 IEC/UL 等)及客户要求的老化、温循环、湿热与机械冲击测试。采购与使用时建议向供应商确认批次记录、RoHS 合规性与包装方式以满足生产与质保需求。

七、订购信息与型号解析

型号示例 CSA0603X7R333K500JT 可拆解为:系列(CSA)+ 封装(0603)+ 介质(X7R)+ 容值编码(333 → 33nF)+ 精度(K → ±10%)+ 电压(500 → 50V)+ 包装/终端与出厂代码(JT 通常指带卷盘/贴片包装等)。订购时请确认所需数量、包装卷盘长度及是否需要特殊筛选或电性能测试报告。

如需更详细的回流曲线、焊盘推荐尺寸、或可靠性试验数据(如湿热、温循环结果),可提供具体项目需求,我可协助匹配或向供应渠道查询相应技术资料。

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
