0805B474K500CT陶瓷电容器产品概述

一、产品基本身份与核心定位

0805B474K500CT是华新科(Walsin) 推出的通用型多层陶瓷电容器(MLCC),属于其标准商用系列产品。型号各部分含义明确:

  • 「0805」:英制封装尺寸(对应公制2012,即2.0×1.2mm);
  • 「474」:容值编码(47×10⁴ pF = 470nF/0.47μF);
  • 「K」:容值精度±10%;
  • 「500」:额定直流电压50V;
  • 「CT」:封装细节标识(对应常规焊接兼容性及等级)。

该产品定位为中低压通用滤波/耦合元件,兼顾成本与性能稳定性,适配多数电子电路的基础电气需求。

二、核心电气性能参数详解

关键电气参数符合行业标准,具体如下:

  1. 容值与精度:标称容值470nF(0.47μF),精度±10%(K档),满足多数电路对容值偏差的容忍要求;
  2. 额定电压:直流额定电压50V,交流应用需按降额规则使用(通常降额至额定电压的50%以下);
  3. 损耗特性:典型损耗角正切(tanδ)≤2.5%(1kHz、25℃测试条件),保证电路能量损耗低;
  4. 绝缘性能:绝缘电阻≥10⁹ Ω(25℃、10V DC、1分钟测试),抗漏电能力符合常规电路要求;
  5. 频率特性:在10kHz~100MHz频段内,容值变化≤±5%,适配中高频电路应用。

三、封装与机械规格

采用0805(2012公制) 表面贴装封装,机械规格如下:

  • 封装尺寸:英制0.08×0.05英寸(公制2.0±0.2mm×1.2±0.2mm);
  • 引脚间距:典型0.5mm(符合IPC-J-STD-001焊接标准);
  • 厚度:常规0.8±0.1mm(适配多数PCB板的组装密度);
  • 焊接兼容性:支持回流焊、波峰焊工艺,无铅无卤,符合RoHS 2.0及REACH环保要求;
  • 机械强度:抗弯能力≥20N,可承受PCB板轻微形变而不失效。

四、温度特性与环境适应性

基于X7R温度系数,产品环境适应性突出:

  1. 温度范围:工作温度-55℃~+125℃,覆盖工业、汽车等领域的宽温需求;
  2. 容值稳定性:在全温度范围内,容值变化≤±15%(符合EIA标准),避免温度波动导致电路性能漂移;
  3. 可靠性测试:通过高温负载寿命(HTOL)测试(125℃、50V DC下1000小时),容值变化≤±10%,绝缘电阻无明显下降;
  4. 温湿度稳定性:符合MIL-STD-202方法106(湿度循环),经85℃/85%RH环境1000小时后,性能仍保持稳定。

五、品牌与可靠性保障

华新科作为全球前五大MLCC制造商之一,该产品具备以下优势:

  1. 认证齐全:通过ISO 9001质量管理体系、IATF 16949汽车级认证,部分批次符合AEC-Q200标准;
  2. 产能稳定:采用自动化生产线,年产能充足,可满足批量订单需求;
  3. 环保合规:无铅无卤,符合欧盟RoHS 2.0、美国加州65号提案等环保法规;
  4. 售后支持:提供完整的技术文档及样品支持,针对应用场景可提供定制化建议。

六、典型应用场景

0805B474K500CT因性能均衡、成本可控,广泛应用于以下领域:

  1. 消费电子:智能手机、平板电脑、智能穿戴设备的电源滤波、信号耦合电路;
  2. 工业控制:PLC可编程控制器、变频器、传感器模块的EMI滤波及旁路电容;
  3. 汽车电子:车载信息娱乐系统、仪表盘、辅助驾驶传感器的低压电路(需确认是否为汽车级批次);
  4. 通信设备:路由器、交换机、基站RRU的电源模块旁路、射频电路耦合;
  5. 家电产品:智能电视、空调、洗衣机的控制板滤波电路。

该产品是一款性能可靠、应用广泛的通用MLCC,适合多数电子电路的基础设计需求,是工程师选型的高性价比选择。

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
