0603B474K250CT 多层陶瓷电容(MLCC)产品概述

一、产品基本属性与核心参数

0603B474K250CT是华新科(Walsin) 推出的小型表面贴装多层陶瓷电容(MLCC),核心定位为高密度电路设计中的通用滤波、耦合元件,核心参数如下:

  • 标称容值:470nF(对应3位编码“474”,即47×10⁴pF)
  • 精度等级:±10%(标识“K”)
  • 额定电压:25V DC(直流额定,交流应用需按厂商降额曲线调整)
  • 温度系数:X7R(符合EIA标准)
  • 封装形式:0603(英制,对应公制1608)

二、封装与尺寸规格

采用0603小型SMD封装,适配高密度PCB布局,尺寸参数符合行业标准:

  • 公制尺寸:长1.60±0.15mm × 宽0.80±0.15mm × 高0.85±0.10mm
  • 英制尺寸:长0.063±0.006英寸 × 宽0.031±0.006英寸
  • 端电极:镍-锡(Ni/Sn)镀层,兼容无铅回流焊(260℃峰值温度,持续≤10秒),焊接附着力强,抗腐蚀性能优异

三、材料特性与温度稳定性

介质采用X7R型钛酸钡基陶瓷,平衡了介电常数与温度稳定性,关键特性:

  • 温度范围:-55℃至+125℃(覆盖工业、汽车电子宽温需求)
  • 容值变化:工作温度内容值波动≤±15%(相对于25℃基准),优于高介电常数的Y5V材料
  • 介电常数:典型值2000-3000,兼顾容量密度与温度稳定性,避免高介电材料的“偏置降容”问题

四、电气性能表现

1. 直流参数

  • 绝缘电阻(IR):25℃时≥10⁹Ω·μF(或≥10⁴MΩ,取较小值);125℃高温下≥10⁶Ω·μF
  • 损耗角正切(DF):1kHz、25℃时≤1.5%,适合电源滤波等低损耗场景

2. 电压与偏置特性

  • 直流偏置敏感度:25V偏置下容值变化≤10%,远低于Y5V材料(通常≥30%),适合需要稳定容值的电源电路
  • 纹波电流能力:额定电压下可承受中等纹波电流(典型值约100mA@1kHz),需结合电路实际负载降额

五、典型应用场景

因体积小、稳定性好,广泛覆盖以下领域:

  1. 消费电子:智能手机、平板的电源滤波、音频耦合,适配高密度PCB设计
  2. 工业控制:PLC、传感器模块的去耦电容,适应-40℃至+85℃的工业环境
  3. 通信设备:路由器、交换机的射频电路滤波,X7R温度稳定性保证信号传输质量
  4. 汽车电子:车载信息娱乐系统、车身控制模块的辅助电源滤波(华新科部分产品具备AEC-Q200认证)
  5. 物联网设备:智能家居、可穿戴设备的电源管理电路,低功耗设计下的可靠选型

六、可靠性与环境适应性

  • 焊接可靠性:通过IPC-J-STD-020无铅回流焊认证,端电极无脱落、开裂风险
  • 环境测试:符合IEC 60068-2-67湿热测试(95%RH、40℃下1000小时性能稳定);抗振动(10-2000Hz,1.5g加速度)与冲击(50g峰值)能力达标
  • 寿命特性:额定条件下平均无故障时间(MTBF)≥10⁶小时,满足长期可靠运行需求

该产品凭借华新科成熟的MLCC生产工艺,在性价比与可靠性上达到平衡,是小型化电路设计的通用优选元件。

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
