0402B104K250CT 陶瓷电容器产品概述

一、产品核心参数总览

0402B104K250CT是华新科(Walsin) 推出的0402封装多层陶瓷电容器(MLCC),专为小型化电子设备的电源滤波、信号耦合等场景设计,核心参数清晰明确:

参数项 规格值 技术说明 标称容值 100nF(104) EIA代码“104”=10×10⁴ pF=100nF 容值精度 ±10%(K) 工业常用精度等级,EIA代码K对应±10% 额定电压 25V DC 连续工作直流电压上限 温度系数 X7R 陶瓷介质温度特性(-55℃~+125℃) 封装尺寸 0402(1005) 英制0402=公制1005(长1.0mm×宽0.5mm) 环保标准 RoHS/REACH 无铅无卤,符合全球环保要求

二、封装与物理细节

0402(1005公制)是目前消费电子领域最常用的小型化贴片封装之一,具体物理参数如下:

  • 长:1.0±0.2mm,宽:0.5±0.2mm,典型厚度:0.5±0.1mm;
  • 端电极:采用锡铅合金(无铅版本为锡银铜),兼容回流焊、波峰焊工艺,焊接可靠性高;
  • 适用场景:特别适合智能手机、智能穿戴、物联网终端等对空间要求严苛的设备,可实现高密度贴片布局。

三、电气性能特性

除核心参数外,该产品的电气性能均衡,满足多数中低端到中端电路需求:

  1. 损耗因子(DF):1kHz测试下≤2.5%,远低于普通电解电容,适合高频滤波场景;
  2. 绝缘电阻(IR):25℃、25V DC条件下≥10⁹Ω,可有效抑制漏电流,保证电路稳定性;
  3. 耐电压能力:额定电压25V,短时过压(如30V DC)可耐受10秒,满足突发电压波动需求。

四、X7R介质的温度稳定性优势

X7R是多层陶瓷电容中温度稳定性较好的介质之一,其特性明确:

  • 工作温度范围:-55℃~+125℃(覆盖工业级温度要求);
  • 容值变化率:±15%(相对于25℃基准值),远优于Y5V介质(容值变化可达±20%以上);
  • 应用价值:可避免因环境温度变化导致的容值漂移,适合工业控制、车载电子(非车规级)等宽温场景。

五、典型应用场景

该产品因小型化、稳定性好的特点,广泛应用于以下领域:

  1. 消费电子:智能手机主板的CPU供电滤波、摄像头模块信号耦合;
  2. 物联网终端:低功耗传感器节点的电源去耦、无线模块匹配;
  3. 工业控制:PLC模块的数字电路滤波、小型电机驱动电路耦合;
  4. 通信设备:路由器、小型基站的射频辅助滤波、电源模块旁路。

六、品牌与可靠性说明

华新科(Walsin)是全球知名被动元件制造商,成立于1971年,其MLCC产品具备以下可靠性优势:

  • 生产工艺:采用先进的多层印刷技术,容值一致性好,批量生产良率高;
  • 可靠性测试:通过高温寿命测试(1000小时@125℃、25V DC),容值变化≤±10%,绝缘电阻≥10⁸Ω;
  • 供应链稳定:全球布局生产基地,可满足中小批量到大规模量产需求。

七、选型参考要点

若需调整参数适配不同场景,可参考以下替代方向:

  1. 精度升级:需±5%精度可选择0402B104J250CT(J对应±5%);
  2. 电压升级:需50V额定电压可选择0402B104K500CT;
  3. 温度升级:需-55℃~+150℃宽温可选择X8R介质的同类产品(如0402B104K250X);
  4. 封装升级:若空间允许,0603(1608)封装的同类产品容值一致性更佳,但体积增加约2倍。

总结

0402B104K250CT作为华新科的经典小型化MLCC,以高温度稳定性、小体积、均衡电气性能为核心优势,覆盖了消费电子、工业控制等多领域的常规需求,是中低端电子设备高密度设计的优选方案之一。

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
