CSA0402X7R104K160GT 贴片电容产品概述

一、产品基本属性

CSA0402X7R104K160GT是HRE(芯声)品牌推出的通用型多层陶瓷贴片电容(MLCC),型号标识精准对应核心参数:

  • 前缀“CSA”为HRE品牌专用系列代码;
  • “0402”代表英制封装规格(公制1005,即长1.0mm×宽0.5mm),属于小型化贴片封装;
  • “X7R”为陶瓷温度系数标准代码;
  • “104”表示容值为100nF(10×10⁴ pF);
  • “K”为精度等级(±10%);
  • “160”代表额定直流工作电压16V;
  • 后缀“GT”为HRE内部工艺/包装标识。

该产品采用表面贴装工艺,适配自动化生产,是电子电路中滤波、耦合、去耦的核心通用元件。

二、核心技术参数详解

1. 容值与精度

容值标称100nF(104),精度等级为K档(±10%),实际容值范围90nF~110nF,满足大多数通用电路对容值偏差的要求,兼顾成本与性能平衡。

2. 额定电压

额定直流工作电压为16V,需注意:

  • 交流电路中峰值电压不得超过16V,否则可能导致陶瓷介质击穿;
  • 实际应用建议留10%~20%电压余量,避免纹波峰值超出额定值。

3. 温度系数(X7R)

“X7R”定义为:

  • 工作温度范围:-55℃ ~ +125℃;
  • 容值变化率:±15%以内(相对于25℃基准容值)。
    对比NPO(超稳定但容值密度低)、Y5V(容值随温度变化大),X7R兼顾容值密度与宽温稳定性,适合复杂环境下的通用电路。

4. 封装规格

封装为0402(英制),公制尺寸1.0mm×0.5mm,厚度约0.5mm(依HRE工艺略有差异)。小体积设计可大幅降低PCB占用面积,适配高密度集成设备(如智能手机、智能穿戴)。

三、材料与工艺特点

1. 陶瓷介质材料

采用X7R基钛酸钡陶瓷,介电常数(εᵣ)约2000~4000,在小体积下实现100nF容值,同时避免容值随温度剧烈波动。

2. 多层叠层工艺

采用MLCC多层叠层结构,交替叠放陶瓷介质层与电极层,相同体积下容值密度比单层电容高数十倍,实现0402封装下的100nF容值。

3. 电极与封装

  • 电极采用镍(Ni)基材料,符合RoHS环保要求(无铅、无镉);
  • 外部封装为环氧树脂涂层,耐潮湿、抗机械冲击,提升焊接可靠性与产品寿命。

四、典型应用场景

该产品因体积小、性能稳定,广泛应用于:

  1. 消费电子:智能手机、平板的电源滤波(去除直流纹波)、音频/射频信号耦合;
  2. 通信设备:路由器、交换机的射频匹配、高频去耦(抑制噪声);
  3. 工业控制:小型PLC、传感器模块的EMI滤波(减少电磁干扰);
  4. 物联网:低功耗IoT节点的电源管理滤波(稳定工作电压);
  5. 汽车电子:车载显示屏、胎压传感器的辅助电源电路(适配-40℃~+85℃车载环境)。

五、选型与使用注意事项

1. 电压与温度匹配

  • 工作电压≤16V(直流),交流峰值≤16V;
  • 环境温度需在-55℃~+125℃内,超出会导致容值偏差增大或介质老化。

2. 焊接工艺

  • 优先回流焊,温度曲线:峰值230℃245℃,回流时间3060秒;
  • 避免波峰焊(0402小封装易受焊锡冲击脱落);
  • 开封后建议12个月内使用,避免受潮氧化。

3. 精度调整

若电路需±5%精度(如射频匹配),需更换J档精度产品;高频下容值略有下降(约5%~10%),需预留余量。

该产品是通用电路中性价比极高的贴片电容,可满足多数中低端电子设备的滤波、耦合需求,是HRE品牌的经典通用型号之一。

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
