华新科1206B333K631CT 多层陶瓷电容器(MLCC)产品概述

华新科(Walsin)1206B333K631CT是一款针对高压、中等容值场景设计的多层陶瓷电容器(MLCC),采用1206表面贴装封装,平衡了电气性能、温度稳定性与可靠性,广泛应用于电源、工业控制、照明等领域。

一、产品核心参数与标识解析

该型号的参数可通过编码直观拆解,核心指标清晰明确:

  • 容值:33nF(0.033μF),由编码“333”表示(33×10³ pF);
  • 精度:±10%,对应编码“K”(电容精度等级K的标准范围);
  • 额定电压:630V DC,由“631”编码解析(63×10¹ V);
  • 温度系数:X7R(行业常用温度稳定型材料);
  • 封装:1206(英制封装代码,公制对应3216,即长3.2mm、宽1.6mm)。

型号末尾“CT”为华新科内部工艺/批次标识,代表商业级常规生产规格,适配主流应用需求。

二、封装与物理特性

1206B333K631CT采用表面贴装型(SMD)1206封装,物理尺寸符合国际电子封装标准:

  • 英制尺寸:长120mil(3.05mm)、宽60mil(1.52mm);
  • 公制尺寸:长3.2mm、宽1.6mm;
  • 典型厚度:约0.8mm(具体参数可参考华新科官方 datasheet);
  • 引脚间距:约1.2mm,适配常规贴片机的吸嘴与回流焊工艺。

该封装为无铅无卤设计,符合RoHS 2.0、REACH等环保法规,无镉、铅、汞等有害物质,满足绿色制造要求。

三、X7R陶瓷材料的温度稳定性

该型号采用X7R铁电陶瓷材料,是MLCC中兼顾容值与温度稳定性的主流选择,核心特性:

  • 温度范围:-55℃至+125℃;
  • 容值变化率:在上述温度范围内,容值波动≤±15%(行业X7R标准);
  • 介电常数:约2000~4000(高于NP0类材料,可实现中等容值)。

相比Y5V等低成本材料,X7R的温度稳定性更优;相比NP0(C0G),X7R可提供更高容值,适合对精度要求不苛刻但需宽温稳定的场景。

四、电气性能关键优势

  1. 高额定电压:630V DC的额定电压可直接应用于高压直流电路,无需串联降压,简化电路设计;
  2. 适中精度:±10%的精度满足大部分工业、消费电子的常规需求,兼顾成本与性能;
  3. 低损耗:MLCC多层结构与陶瓷材料特性,使其在1MHz以下工作频率下损耗极低,适合滤波、耦合等应用;
  4. 无极性设计:无需区分正负极,贴装与使用更便捷,降低装配错误风险;
  5. 高绝缘性:典型绝缘电阻≥10⁹Ω,可有效抑制电磁干扰(EMI),提升电路稳定性。

五、典型应用场景

1206B333K631CT的参数特性使其适用于以下场景:

  • 电源电路:开关电源、LED驱动电源的高压直流滤波,抑制纹波噪声;
  • 工业控制:PLC(可编程逻辑控制器)的高压信号耦合、传感器接口滤波;
  • 照明领域:LED背光电源、高压钠灯驱动电路的滤波与耦合;
  • 消费电子:电视、显示器的高压电源滤波(如背光升压电路);
  • 通信设备:中低频射频电路的辅助滤波(如电源模块滤波)。

六、可靠性与环境适应性

该型号经华新科严格可靠性测试,满足以下标准:

  • 温度适应性:工作温度-55℃+125℃,存储温度-55℃+150℃;
  • 机械可靠性:抗振动(10Hz~2000Hz,加速度10G)、抗冲击(峰值加速度1000G,持续0.1ms),适合车载、工业等振动环境;
  • 湿度适应性:90%RH(40℃)环境下连续工作1000小时,容值变化≤±5%;
  • 寿命:在额定电压、85℃温度下,平均寿命≥10万小时。

总结

华新科1206B333K631CT是一款高性价比的高压MLCC,通过X7R材料实现宽温稳定,1206封装适配主流贴装工艺,体积远小于传统高压电解电容,寿命更长,是电源、工业、照明等领域的理想选择。

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
