1206B222K102CT 多层陶瓷电容器(MLCC)产品概述

1206B222K102CT是华新科(Walsin)推出的一款高电压多层陶瓷电容器(MLCC),专为工业、通信、电源等领域的高压场景设计,具备稳定的温度特性与可靠的电气性能,符合EIA标准封装要求。

一、产品核心身份与技术定位

该型号属于华新科常规MLCC产品线,采用多层陶瓷叠层结构(将陶瓷介质层与内电极交替叠合,经高温烧结而成),核心定位为高压小容值滤波/耦合/旁路电容,解决传统电容在高电压场景下的容量稳定性与可靠性问题,适配自动化表面贴装(SMT)工艺。

二、关键电气性能参数

1206B222K102CT的核心电气参数完全匹配高电压应用需求,具体如下:

  • 容值:2.2nF(2200pF),料号中“222”为容值编码(22×10²pF);
  • 精度:±10%,编码“K”代表精度等级,满足一般工业场景的容值偏差要求;
  • 额定电压:1000V(直流),是该型号的核心高压指标,可长期工作在高压侧电路;
  • 温度系数:X7R,对应工作温度范围-55℃至+125℃,容值变化率≤±15%;
  • 绝缘电阻:典型值≥10¹⁰Ω·V(25℃,100V直流),绝缘性能优异,减少漏电流;
  • 损耗角正切(tanδ):≤0.01(1kHz,25℃),低损耗适合高频电路的信号传输与噪声抑制。

三、封装与尺寸规格

该型号采用EIA 1206封装(英制),对应公制尺寸3216,具体物理参数如下:

  • 长×宽:3.2mm×1.6mm(公差±0.2mm),符合SMT标准贴装尺寸;
  • 厚度:典型值1.0mm(部分批次为0.8mm,需以官方 datasheet 为准);
  • 端电极:镀锡端电极,兼容回流焊、波峰焊工艺,贴装后焊接可靠性高。

四、温度特性与可靠性表现

X7R温度系数是该型号的核心优势之一,其陶瓷介质基于钛酸钡基材料,具备以下特性:

  1. 宽温稳定性:在-55℃至+125℃范围内,容值变化率控制在±15%以内,避免极端温度下性能波动;
  2. 高压可靠性:1000V额定电压经过1.5kV/2s过压测试,抗电晕能力强,适合长期高压工作;
  3. 低寄生参数:叠层结构带来低ESR(等效串联电阻)与低ESL(等效串联电感),适合高频电路的噪声抑制与信号耦合。

五、典型应用场景

1206B222K102CT因高压、稳定的特性,广泛应用于以下领域:

  • 电源系统:开关电源、LED驱动电源的高压侧滤波(如PFC电路、输出高压滤波);
  • 通信设备:射频模块的信号耦合电容(如基站功放、微波通信链路);
  • 工业控制:变频器、PLC的高压旁路电容(抑制电磁干扰EMI);
  • 医疗电子:部分高压医疗设备的储能/滤波电容(如小型诊断设备);
  • 消费电子:高端显示器、智能家居设备的高压辅助电路。

六、品牌与品质背书

华新科(Walsin)作为全球前五大被动元器件厂商之一,具备超过50年的MLCC生产经验,该型号满足以下标准:

  • 环保合规:符合RoHS 2.0、REACH SVHC等环保指令,无铅无卤;
  • 可靠性测试:经过温度循环(-55℃~+125℃,1000次)、湿度测试(85℃/85%RH,1000h)等严格验证;
  • 行业认证:产品通过UL、VDE等安全认证,可适配全球市场需求。

综上,1206B222K102CT是一款兼顾高压性能、温度稳定性与贴装兼容性的MLCC,适合对电气性能要求较高的高压应用场景,是工业、通信等领域的可靠被动元件选择。

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
