华新科0402B474K100CT陶瓷电容器产品概述

一、产品基本定位

0402B474K100CT是华新科(Walsin)推出的通用型多层陶瓷电容器(MLCC),属于X7R温度系数系列,主打超小体积、稳定容值与高可靠性,适配高密度表面贴装(SMT)电路设计,广泛覆盖消费电子、IoT设备等小型化场景。

二、核心性能参数详解

该型号的关键参数可通过编码及官方规格明确,核心指标如下:

  1. 容值与精度:标称容值为470nF(0.47μF),型号中“474”代表容值编码(47×10⁴ pF=470000pF=470nF);精度为**±10%**(型号中“K”为精度代码),满足多数通用电路对容值偏差的要求(如电源滤波、信号耦合无需更高精度时)。
  2. 额定电压:10V直流(DC),是最大连续工作电压,实际应用建议降额至8V以内(80%降额),可显著提升长期可靠性,避免电压波动导致的击穿风险。
  3. 温度系数:X7R,平衡成本与稳定性的经典系数,温度范围覆盖**-55℃至+125℃**,容值变化率控制在±15%以内——既适配户外IoT设备的低温环境,也能应对充电设备的高温场景。
  4. 封装规格:0402英寸(公制1005),即长1.0mm×宽0.5mm的超小封装,是消费电子最常用的小型化封装之一,适配细间距PCB布局,支持高速SMT贴装。

三、封装与物理特性

0402封装的典型物理参数:

  • 长度:1.016mm(0.04英寸)
  • 宽度:0.508mm(0.02英寸)
  • 高度:约0.5mm(同批次偏差≤0.1mm)
  • 焊盘兼容性:适配标准0402 SMT焊盘(建议尺寸0.6mm×0.3mm,间距0.2mm),焊接可靠性符合IPC-A-610标准,支持回流焊、波峰焊工艺。

四、典型应用场景

因体积小、容值稳定,该型号广泛用于:

  1. 消费电子终端:智能手机/平板的电源滤波(去除电池高频噪声)、音频电路耦合(连接扬声器与功放);
  2. 小型IoT设备:蓝牙耳机的射频匹配电容(稳定蓝牙信号)、智能手环的MCU电源去耦;
  3. 工业小型模块:温湿度传感器节点的信号滤波、小型PLC的辅助电源电路;
  4. 车载低功耗部件:汽车钥匙、胎压监测模块的电源稳压电容(满足宽温要求)。

五、品牌与可靠性优势

华新科作为全球TOP级被动元器件供应商,该型号具备:

  1. 工艺稳定性:多层叠层陶瓷工艺,介质均匀性好,同批次容值一致性≤5%;
  2. 环保与认证:符合RoHS 2.0、REACH标准,通过IEC 60384-14、UL认证,适合全球市场;
  3. 抗老化性能:X7R介质老化率低(长期工作容值漂移≤5%),满足5年以上使用寿命要求;
  4. 质量控制:每批次100%耐压测试、容值分选,不良率≤10ppm(百万分之一)。

六、选型与使用注意事项

  1. 电压降额:避免工作电压接近10V,最大连续电压≤8V,脉冲电压≤12V(短时间);
  2. 温度适配:若环境温度超125℃,需换X8R等更高温系数型号;
  3. 精度调整:若需±5%精度(如射频电路),替换为“J”精度代码型号(如0402B474J100CT);
  4. 封装兼容:确认PCB焊盘符合0402要求,避免贴装偏移或焊接不良。

该型号凭借高性价比与稳定性能,成为小型化电路设计的主流选择之一。

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
