0805X475K250CT 片式陶瓷电容产品概述

一、产品基本信息

0805X475K250CT是华新科(Walsin) 推出的片式多层陶瓷电容(MLCC),核心参数与封装明确对应:

  • 封装规格:0805(英寸制,公制对应2012,尺寸2.0mm×1.25mm);
  • 容值标识:4.7μF(“475”=47×10⁵ pF);
  • 精度:±10%(字母“K”为EIA精度代码);
  • 额定电压:25VDC(“250”代表25V直流工作电压);
  • 材质:X5R高介电常数陶瓷。

该产品属于华新科通用型MLCC系列,适配自动化贴装工艺,广泛用于电子设备的滤波、耦合及电源旁路场景。

二、X5R材质的温度稳定性

X5R是该电容的核心材质标识,其温度特性符合EIA标准:

  • 工作温度范围:-55℃至+85℃;
  • 容值变化率:相对于25℃基准值,控制在±15%以内。

相比NPO(COG)材质的低容值稳定,X5R兼顾了高容值密度与温度可靠性,避免了Y5V材质高温下容值漂移过大的问题,适合对容值敏感度适中的电路(如电源滤波、信号耦合)。

三、关键电气性能参数

经华新科测试验证,核心电气指标如下(标准测试条件:1kHz,0.1Vrms):

  1. 容值:4.7μF ±10%(批量一致性稳定);
  2. 绝缘电阻(IR):常温≥10GΩ·μF,85℃高温下≥1GΩ·μF(防漏电关键指标);
  3. 损耗角正切(DF):≤5%(低损耗减少电路能量损耗);
  4. 谐振频率:约15MHz(典型值,适配中低频滤波需求);
  5. 额定电压:25VDC(最大直流工作电压,交流电压需降额至≤10Vrms)。

四、机械性能与可靠性

采用多层陶瓷叠层工艺,机械性能符合国际标准:

  • 封装尺寸:2.0±0.2mm(长)×1.25±0.15mm(宽)×1.0±0.1mm(厚),适配标准0805贴装工位;
  • 焊接兼容性:支持回流焊(260℃/10s峰值)、波峰焊(240℃/5s峰值)及手工焊接(350℃/3s),无热开裂风险;
  • 振动与冲击:通过10-2000Hz/1.5g振动测试(200h)、100g冲击测试(11ms半正弦波),性能无衰减;
  • 寿命可靠性:高温负荷寿命(85℃/25VDC/1000h)后,容值变化≤±10%,绝缘电阻≥1GΩ。

五、典型应用场景

因容值适中、电压适配性强,广泛用于:

  1. 消费电子:智能手机/平板的电源滤波(电池管理、射频模块旁路)、音频耦合;
  2. 工业控制:PLC输入输出模块、传感器信号滤波、小型电机驱动电路;
  3. 通信设备:路由器/交换机的电源模块滤波、以太网接口耦合;
  4. 电源电路:DC-DC转换器输入/输出滤波、线性电源稳压旁路;
  5. 汽车电子:车载IVI(信息娱乐系统)小信号电路(需确认车规级版本,常规为商业级)。

六、选型与使用注意事项

  1. 电压降额:实际工作电压≤25VDC,交流电压需按有效值降额(建议≤10Vrms);
  2. 焊接规范:避免超过回流焊260℃峰值,手工焊接温度≤350℃,时间≤3s;
  3. 储存环境:未开封产品存于-40℃~+60℃、湿度≤60%环境,开封后1个月内用完(防受潮);
  4. 机械应力:贴装时避免过大压力,焊接后勿弯折PCB(防陶瓷开裂);
  5. 批量校验:使用前抽样测试容值(1kHz/0.1Vrms),确认±10%精度。

七、品牌与质量保障

华新科是全球被动元器件头部厂商,该产品通过RoHS、REACH环保认证,符合欧盟及国内环保标准;生产遵循ISO 9001体系,每批次附带合格证明,支持OEM/ODM厂商质量追溯。

该产品以高性价比、稳定性能成为通用电路的主流选型,覆盖多领域电子设备的基础滤波需求。

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
