华新科1206B475K500CT片式陶瓷电容产品概述

一、产品核心规格参数

1206B475K500CT是华新科推出的1206封装X7R材质片式陶瓷电容,型号命名规则清晰对应核心参数:

  • 封装类型:1206(英制代码,对应公制尺寸3.2mm×1.6mm×1.6mm,适配SMT自动贴装);
  • 标称容值:4.7μF(代码“475”:47×10⁵pF=4.7μF);
  • 精度等级:±10%(字母“K”标注);
  • 额定电压:50V DC(直流工作电压,交流峰值不超过50V);
  • 材质类型:X7R(高介电常数陶瓷,兼顾容量密度与温度稳定性);
  • 工作温度:-55℃至+125℃(符合X7R材质标准);
  • 环保认证:RoHS 2.0、REACH(无铅无卤,满足全球环保要求)。

二、材质与性能特点

X7R材质是片式陶瓷电容中高容量场景的主流选择,1206B475K500CT的核心性能优势:

  1. 高容量密度:1206小封装实现4.7μF容量,解决“小体积+大容量”的设计矛盾;
  2. 温度稳定性:在-55℃+125℃范围内,容值变化≤±15%(优于Y5V材质的±20%-80%),适合宽温环境;
  3. 偏置特性平缓:直流偏置下容值衰减率低(额定电压50%时衰减≤10%),适配电源滤波场景;
  4. 低损耗:1kHz/25℃下损耗角正切值(tanδ)≤2.5%,适合信号耦合与高频滤波。

三、典型应用场景

1206封装适配高密度PCB设计,1206B475K500CT的应用覆盖多领域:

  1. 消费电子:智能手机/平板的DC-DC输出滤波、音频电路耦合;
  2. 工业控制:PLC I/O接口滤波、传感器信号耦合、电机驱动辅助滤波;
  3. 通信设备:路由器/交换机电源模块滤波、射频前端小信号耦合;
  4. 家电产品:智能电视/空调控制电路滤波、电源板EMI抑制;
  5. 汽车电子:车载中控/倒车影像的低压电源滤波(非安全关键场景,若需车规级需确认AEC-Q200认证)。

四、可靠性与质量保障

华新科作为全球被动元件龙头,1206B475K500CT遵循严格质量标准:

  1. 焊接可靠性:通过260℃回流焊3次测试,无开裂、剥离失效;
  2. 耐电压性能:额定电压下连续工作1000小时,容值变化≤±5%,绝缘电阻≥10⁹Ω;
  3. 环境适应性:通过-55℃~+125℃温度循环1000次、85℃/85%RH高湿存储1000小时测试;
  4. 批量一致性:量产批次容值、电压偏差控制在规格范围内,适合大规模生产。

五、选型与替换说明

  1. 直接匹配场景:需“1206封装、4.7μF±10%、50V DC、X7R材质”的项目,该型号为最优选择;
  2. 替换参考:
    • 更高精度(±5%):选同封装475J系列(J代表±5%);
    • 更高电压(100V):选1206B475K100CT;
    • 更低温度系数(±0.5%):需切换NPO材质(但1206封装NPO最大容值仅1000pF,无法实现4.7μF);
  3. 应用限制:不建议用于高精度时钟、射频前端(需NPO)或超50V高压场景。

该产品平衡了容量、体积与稳定性,是中低端电子设备电源滤波、信号耦合的高性价比选择。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
