CSA0402X7R104K500GT 多层陶瓷贴片电容(MLCC)产品概述

一、产品核心身份与定位

CSA0402X7R104K500GT是HRE芯声品牌推出的0402封装通用型多层陶瓷贴片电容(MLCC),属于工业级常规应用的中高压电容产品。型号命名清晰对应核心参数:“0402”为英制封装尺寸,“X7R”为陶瓷介质类型,“104”代表100nF容值,“K”表示±10%精度,“500”对应50V额定电压,“GT”为包装/编带规格标识。该产品以“小体积、稳定性能、宽温适配”为核心优势,覆盖消费电子、工业控制、汽车电子等多领域的常规电路需求,是替代进口同类产品的高性价比选择。

二、关键电气性能参数解析

该产品的核心电气参数围绕“通用场景适配”设计,具体如下:

  • 容值与精度:100nF(即10⁴pF,型号中“104”为容值编码),精度±10%(字母“K”标注),满足大多数非精密电路的滤波、耦合需求,无需额外校准;
  • 额定电压:50V直流额定电压,高于常规0402封装的16V/25V规格,可适配电压稍高的电源电路(如DC-DC转换模块输出端);
  • 温度系数:X7R陶瓷介质,温度范围-55℃~+125℃,容值变化控制在±15%以内——相比NPO(温度稳定但容值偏小)和Y5V(容值大但温度特性差),X7R在“容值范围”与“温度稳定性”间实现平衡,适合宽温环境;
  • 封装尺寸:0402英制(公制1005,即1.0mm×0.5mm),体积仅为常规插件电容的1/10左右,适配高密度PCB设计。

三、材料与封装工艺特性

作为多层陶瓷电容,该产品的材料与工艺直接决定性能可靠性:

  • 介质材料:采用X7R钛酸钡基陶瓷,通过多层叠层烧结工艺(数十层陶瓷介质与电极交替堆叠),在小体积内实现高容值,同时降低等效串联电阻(ESR)与等效串联电感(ESL);
  • 电极结构:内部电极采用镍(Ni)材料(环保无铅),端电极采用“镍+锡/银”三层结构,既保证焊接兼容性(符合RoHS、REACH标准),又减少焊接时的接触电阻;
  • 封装与包装:0402贴片封装,表面贴装设计适配自动化SMT产线;包装为8mm卷带编带(10000pcs/卷),符合EIA-481标准,便于批量生产;
  • 尺寸与重量:典型尺寸1.0±0.1mm(长)×0.5±0.1mm(宽)×0.5±0.05mm(厚),重量约0.002g,适合便携设备的轻量化需求。

四、典型应用场景

该产品因“宽温、中高压、小体积”特性,广泛应用于以下场景:

  • 消费电子:智能手机、平板电脑、智能手表的电源滤波(DC-DC转换后滤波)、信号耦合(音频、射频辅助滤波);
  • 汽车电子:车载中控、仪表盘的小功率电路滤波(适配-40℃~85℃车载环境)、传感器信号去耦;
  • 工业控制:PLC模块、小型变频器的电源滤波、控制电路去噪;
  • 通信设备:路由器、交换机的电源模块滤波、以太网接口辅助滤波;
  • 小型家电:蓝牙耳机、智能家居设备的内部电源与信号电路。

五、可靠性与环境适应性

HRE芯声对该产品的可靠性设计符合行业标准,具体表现为:

  • 温度稳定性:-55℃~+125℃范围内,容值变化≤±15%,满足工业级宽温要求;
  • 湿度与耐候性:符合IEC 60068-2-66(湿热试验)标准,95%RH/40℃环境下1000小时性能无明显衰减;
  • 寿命与耐久性:额定电压、25℃条件下,寿命可达10⁶小时以上;若按80%降额使用(≤40V),寿命可进一步延长;
  • 机械性能:抗振动(10~2000Hz,加速度2g)、抗冲击(1000g,0.1ms)性能符合MIL-STD-883标准,适合移动设备;
  • 焊接兼容性:回流焊温度范围230~260℃(峰值260℃/10s),无铅焊接后无开裂、虚焊问题。

六、选型与使用注意事项

为保证产品性能与寿命,使用时需注意以下要点:

  1. 电压降额:实际工作电压建议不超过额定电压的80%(即≤40V),避免过压导致介质击穿;
  2. 温度限制:避免工作环境超过+125℃,否则容值变化超差影响电路性能;
  3. 焊接规范:严格遵循厂家回流焊温度曲线,避免局部过热导致陶瓷开裂;
  4. 存储要求:常温(15~35℃)、干燥(湿度≤60%)环境存储,开封后1个月内使用完毕(避免受潮);
  5. 替代兼容性:可直接替代村田GRM155R61C104KA37D、TDK C1005X7R104K500T等进口同类产品,电气参数与封装尺寸完全匹配。

该产品凭借稳定的性能与高性价比,已成为中小批量电子设计的优选电容之一,适合各类对成本敏感但需保证可靠性的应用场景。

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.
