1206B102J202CT多层陶瓷电容器(MLCC)产品概述

一、产品核心身份与基本定位

1206B102J202CT是华新科(Walsin) 推出的表面贴装(SMD/SMT)多层陶瓷电容器(MLCC),属于高压、中等精度、宽温稳定型系列产品。该型号通过封装代码、容值代码等组合,清晰对应关键参数:封装1206、容值1nF(1000pF)、额定电压2kV、容差±5%、温度系数X7R,是高压电路中滤波、耦合、EMI抑制的核心被动元件之一。

二、关键电气性能参数详解

1. 容值与精度

容值为1nF(1000pF),采用国际通用电容代码标识(102:10×10²pF);精度等级为J级(±5%),满足多数工业、医疗、电源电路对容值一致性的要求,无需额外筛选即可批量使用。

2. 额定电压与耐压特性

额定电压为2kV(直流),是该型号核心优势——针对高压场景设计,可稳定工作在2kV直流电压下,峰值电压耐受能力符合华新科高压MLCC标准(通常为额定电压1.2~1.5倍),避免高压击穿风险。

3. 温度系数与稳定性

采用X7R温度系数,定义为:工作温度范围**-55℃~+125℃**,此范围内容值变化率≤±15%。相比Y5V等高容变材料,X7R兼具中等精度与宽温稳定性,适合环境温度波动较大的工业、车载场景。

三、物理封装与机械特性

1. 封装尺寸与贴装兼容性

封装为1206(公制3216,英制1206),具体尺寸:长3.2mm±0.2mm、宽1.6mm±0.2mm、厚度≤1.6mm(典型值1.2mm),适配富士、西门子等主流SMD贴片机,贴装精度满足±0.1mm工业要求。

2. 结构与焊接特性

采用多层陶瓷叠层结构,电极材料为镍(Ni)基,表面镀纯锡(无铅),兼容回流焊、波峰焊工艺(回流焊峰值温度240~260℃,时间≤10秒)。焊接后机械强度符合IEC 60068-2-6(振动)、IEC 60068-2-27(冲击)测试标准。

四、典型应用场景

因高压、中等精度、宽温稳定特性,该型号广泛应用于:

  • 高压电源滤波:开关电源PFC电路、高压DC-DC转换器输出滤波,抑制高压纹波;
  • 医疗设备电路:除颤器、高压理疗设备的耦合/滤波,满足医疗级安全要求;
  • 工业控制高压端:高压传感器(压力、温度)信号调理、高压执行器驱动滤波;
  • EMI/RFI抑制:高压通信设备、电力电子设备的电磁干扰抑制,降低共模/差模噪声;
  • 车载高压辅助电路:新能源汽车DC-DC辅助电源滤波,适配-40℃~+85℃车载环境。

五、可靠性与环境适应性

1. 环保与认证

符合RoHS 2.0、REACH 环保标准,无铅无卤;通过ISO 9001(质量)、ISO 14001(环境)、IATF 16949(汽车)认证,满足全球主流市场合规要求。

2. 长期可靠性

  • 高温负载寿命:125℃、额定电压下,1000小时后容值变化≤±2%,损耗角正切(tanδ)变化≤±10%;
  • 湿度稳定性:85℃/85%RH环境下,500小时后容值变化≤±3%;
  • 机械可靠性:振动10~2000Hz(2g加速度)、冲击15g(11ms)下,无开路/短路故障。

六、品牌与质量保障

华新科(Walsin)作为全球前五大MLCC供应商,拥有30年被动元件研发制造经验,1206B102J202CT采用成熟高压MLCC工艺(陶瓷配方、叠层精度控制),产品一致性达批量生产水平。售后支持包括:批量质量追溯、不良品退换、技术参数咨询,满足研发到量产全流程需求。

该型号凭借高压适配性、宽温稳定性与华新科的质量保障,成为高压电路设计的优选被动元件之一。

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
