1206B473K631CT 片式陶瓷电容产品概述

一、产品核心身份识别

1206B473K631CT是华新科(Walsin)推出的中高压片式陶瓷电容,属于其X7R介质系列主力产品。型号命名清晰传递核心参数:

  • “1206”对应英制封装尺寸;
  • “473”表示标称容值47nF(47×10³pF);
  • “K”代表精度±10%;
  • “631”明确额定电压630VDC;
  • “CT”为华新科内部封装工艺标识。

该产品定位为工业级中高压电路的滤波、耦合核心元件,兼顾小型化与可靠性。

二、关键性能参数详解

1206B473K631CT的性能参数围绕“中高压稳定”设计,核心指标如下:

  • 容值与精度:标称47nF(473),精度±10%(K档),满足多数滤波、耦合场景的误差要求;
  • 额定电压:630VDC,覆盖常见工业电源、照明驱动的高压需求;
  • 温度特性:X7R介质,工作温度范围-55℃~+125℃,此区间内容值变化率≤±15%,稳定性远优于Y5V等低阶介质;
  • 封装尺寸:英制1206(公制3216),典型尺寸3.2mm×1.6mm×0.8mm,无引线设计降低寄生电感,适配高密度PCB布局。

三、封装与工艺特性

该电容采用华新科成熟的多层陶瓷叠层工艺(MLCC),工艺优势显著:

  • 介质材料:X7R铁电陶瓷,既保留陶瓷电容高耐压特性,又比C0G介质实现更高容值(1206封装下可稳定实现47nF);
  • 端电极设计:镍(Ni)内层+锡(Sn)外层镀层,符合RoHS无铅环保要求,焊接兼容性好,抗硫化性能优异;
  • 结构可靠性:多层陶瓷经高温烧结一体化成型,无引线结构抗振动、抗冲击能力强,适合工业环境的机械应力场景。

四、适用应用场景

因630VDC额定电压、47nF容值及小型化封装,该电容主要应用于中高压电路的滤波、耦合环节,典型场景包括:

  1. 工业电源:开关电源高压侧滤波(AC-DC转换后高压直流滤波)、辅助电源储能耦合;
  2. 照明驱动:LED高压驱动电源输出滤波、高压钠灯/金卤灯镇流器电路;
  3. 家电控制:变频空调、洗衣机的高压变频模块滤波(如压缩机驱动电路);
  4. 通信设备:基站辅助电源中高压滤波、射频模块耦合电路;
  5. 仪器仪表:高压测试设备信号耦合、滤波环节。

五、品牌与可靠性背书

华新科(Walsin)是全球领先的被动元器件制造商,1206B473K631CT具备可靠的品质保障:

  • 认证资质:通过ISO9001质量管理体系、RoHS2.0、REACH环保认证,部分批次符合ISO/TS16949汽车电子标准;
  • 可靠性测试:经过高温高湿(85℃/85%RH,1000小时)、温度循环(-55℃~+125℃,500循环)、焊接耐热(回流焊峰值240℃)等严格测试;
  • 一致性:自动化生产流程保证产品参数一致性,批次间差异极小。

六、选型与使用注意事项

为确保性能稳定,使用时需注意以下要点:

  1. 电压降额:实际工作电压≤额定电压的80%(≤504VDC),避免过压击穿;
  2. 温度范围:严格控制在-55℃~+125℃内,超出范围会导致容值漂移、损耗增大;
  3. 焊接工艺:优先回流焊,波峰焊浸锡时间≤3秒,焊接温度符合规范(回流焊峰值230~245℃,时间≤30秒);
  4. 储存条件:未开封产品储存在常温干燥环境(≤30℃、≤60%RH),开封后12个月内使用,避免受潮导致焊接爆米花效应;
  5. 精度匹配:若需±5%高精度,需选C0G介质电容,但C0G容值较小(1206封装最大约10nF),不适合47nF需求。

该产品凭借中高压特性、小型化封装及稳定性能,成为工业与消费电子领域中高压电路的优选元件。

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
