0402B105K6R3CT 片式陶瓷电容产品概述

一、产品基本信息

0402B105K6R3CT是华新科(Walsin)推出的通用型片式陶瓷电容,采用X7R介质材料,专为低电压、小型化电子设备设计。型号编码对应核心参数:0402为英制封装尺寸,105表示容值1μF(10×10⁵pF),K代表精度±10%,6R3表示额定电压6.3V,CT为华新科封装与端电极标识。产品定位为消费电子、便携式设备的通用滤波、耦合与去耦元件,兼顾稳定性与成本优势。

二、核心电气参数详解

该电容的关键电气性能符合华新科X7R系列标准,具体如下:

  1. 容值与精度:标称容值1μF(1000nF),精度±10%(K档),满足多数通用电路的容值需求;
  2. 额定电压:直流额定电压6.3V,适配3.3V、5V等主流低电压系统,降额使用可进一步提升可靠性;
  3. 温度特性:X7R介质温度范围为**-55℃~+125℃**,此区间内电容变化率≤±15%,相比Y5V等介质稳定性显著提升;
  4. 损耗特性:1kHz测试频率下,损耗角正切(tanδ)≤2%,低损耗适合信号耦合与高频滤波;
  5. 绝缘性能:25℃环境下,6.3V直流电压1分钟测试,绝缘电阻≥10¹⁰Ω·μF,确保电路绝缘可靠性。

三、封装与物理特性

产品采用0402英制封装(对应公制1005),物理尺寸紧凑,适配高密度PCB设计:

  1. 尺寸规格:长1.0±0.2mm,宽0.5±0.2mm,厚0.5±0.1mm(典型值),满足小型化设备的空间要求;
  2. 端电极结构:三层无铅端电极(Ni/Ag/Sn),符合RoHS 2.0、REACH等环保标准,兼容回流焊、波峰焊工艺;
  3. 焊接兼容性:耐回流焊温度260℃(10秒峰值),焊接后无开裂、剥离等失效风险,适配自动化贴装产线。

四、典型应用场景

基于低电压、小尺寸、中等精度的特性,该电容广泛应用于:

  1. 便携式消费电子:智能手机、平板电脑、智能穿戴(手表/手环)的电源回路去耦、音频信号耦合;
  2. 小型电子设备:蓝牙耳机、MP3播放器、遥控器的滤波电路,抑制电磁干扰;
  3. 物联网终端:低功耗传感器节点、智能家居设备的信号调理电路,实现电源稳压与噪声过滤;
  4. 工业控制模块:小型PLC、传感器模块的辅助滤波,适配低电压控制电路。

五、品牌可靠性与质量保障

华新科作为全球被动元件核心供应商,该产品通过多项可靠性测试:

  1. 环保认证:符合RoHS 2.0(无铅、无镉、无汞)、REACH SVHC清单要求,满足全球市场准入;
  2. 可靠性测试:
    • 温度循环:-55℃~+125℃,500次循环后电容变化≤±10%;
    • 湿度加载:85℃/85%RH环境下1000小时,绝缘电阻≥10⁸Ω;
    • 振动测试:10~2000Hz频率范围,加速度2g,12小时测试无失效;
  3. 质量体系:通过ISO 9001、IATF 16949(汽车级)等认证,生产过程全程管控。

六、选型适配参考

  1. 介质对比:相比Y5V(温度系数大,容值变化达±20%),X7R更适合对温度稳定性有要求的场景;若需更高精度(±5%),可选择J档产品;
  2. 电压适配:电路工作电压≤5V时,6.3V额定电压可满足降额设计(通常降额至70%以下),提升可靠性;
  3. 封装替代:同容值、精度下,若需更大封装(如0603),可参考华新科对应型号,但0402更适合高密度设计。

该产品凭借小尺寸、稳定性能与高可靠性,成为低电压小型化设备的优选被动元件。

Sourcing availability signal

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
