华新科1210B475K101CT多层陶瓷电容产品概述

一、产品基本定位与标识

华新科(Walsin)1210B475K101CT是一款多层陶瓷电容(MLCC),主打中高压、中等容值的通用电子电路场景。型号各部分可快速对应核心参数:

  • 1210:英制封装尺寸(0.12英寸×0.10英寸,公制≈3.2mm×2.5mm);
  • B:温度系数代码(对应X7R);
  • 475:容值编码(47×10⁵pF=4.7μF);
  • K:精度等级(±10%);
  • 101:额定电压编码(10×10¹V=100V DC);
  • CT:华新科常规商用级系列后缀。

二、核心电气性能参数

该电容平衡了容值、电压与温度稳定性,关键指标适配多数通用场景:

  1. 容值与精度:标称4.7μF,精度±10%——无需额外高精度筛选,满足电源滤波、耦合等基础需求;
  2. 额定电压:100V DC——适用于12V/24V系统二次滤波、100V以内信号电路,避免过压击穿;
  3. 温度特性:X7R温度系数——工作范围-55℃~+125℃,容值变化≤±15%(比Y5V更稳定,比C0G容值密度更高);
  4. 损耗与绝缘:25℃/1kHz下损耗角正切≤2.5%(低功耗),50V DC下绝缘电阻≥10⁴MΩ(漏电流小)。

三、封装与物理特性

1210封装是陶瓷电容主流尺寸,适配小型化设计:

  • 尺寸:3.2mm(长)×2.5mm(宽)×1.6mm(厚,典型值)——体积紧凑,可集成到高密度PCB;
  • 电极:镍电极+无铅焊端(符合RoHS),焊接兼容性好;
  • 机械强度:多层陶瓷结构经工艺优化,抗贴装应力优于单层电容,适合批量生产。

四、典型应用场景

因参数均衡,广泛覆盖以下领域:

  1. 消费电子:电视、显示器、机顶盒的电源滤波(如DC-DC输出滤波)、信号耦合;
  2. 工业控制:PLC、变频器的辅助电源、传感器信号去耦;
  3. 通信设备:路由器、交换机的电源模块滤波、射频电路辅助去耦;
  4. 汽车电子:(若为车规级需确认)车载信息娱乐系统、车身控制模块电源滤波(常规CT为商用级)。

五、产品优势与华新科品质

华新科作为全球MLCC龙头,该型号具备三大核心优势:

  1. 容值密度高:1210封装实现4.7μF/100V,比同体积Y5V电容温度稳定性提升3倍以上;
  2. 可靠性稳定:经高温老化、湿度循环测试,失效率≤0.1%/1000小时,适合长期运行设备;
  3. 环保与供货:符合RoHS 2.0、REACH,无铅无镉;产能充足,批量订单交期可控(通常2~4周)。

六、使用与存储注意事项

为避免性能衰减,需注意以下细节:

  1. 焊接参数:无铅回流焊峰值温度≤245℃,波峰焊≤260℃/5秒内(过热易开裂);
  2. 静电防护:陶瓷电容易受ESD损坏,贴装前需用防静电工作台、离子风扇;
  3. 存储条件:常温(15~35℃)、湿度≤60%,存储期≤12个月,开封后1个月内用完(防焊端氧化);
  4. 安装要求:无极性可任意贴装,但避免PCB过度弯曲(防止电容断裂)。

该电容是一款性能均衡、性价比突出的通用MLCC,尤其适合消费电子与工业控制领域的中低压电路设计,是替代进口同类产品的可靠选择。

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
