C1812N102J302T 高压贴片陶瓷电容产品概述

一、产品基本属性

C1812N102J302T是禾伸堂(IHHEC) 推出的高压多层陶瓷贴片电容(MLCC),针对高电压、高精度应用场景优化设计。核心采用C0G(NP0)陶瓷介质,兼具低损耗、宽温稳定性的核心优势,是工业级、医疗级等对性能要求严苛领域的优选元件。

二、核心性能参数

2.1 容值与精度

标称容值为1nF(对应EIA代码“102”),精度等级为±5%(EIA代码“J”),满足多数高精度电路的容值匹配需求。C0G介质的容值受温度、电压影响极小,是替代传统薄膜电容的理想选择。

2.2 额定电压与耐温

额定直流电压为3kV,需遵循高压元件降额原则(建议降额≥50%,即实际工作电压≤1.5kV),避免过压击穿。温度系数为C0G,典型工作温度范围为-55℃至125℃,容值变化率≤±30ppm/℃,宽温下性能稳定可靠。

2.3 损耗与绝缘特性

损耗因数(DF)典型值≤0.15%(1kHz测试条件),低损耗特性适合高频电路及高功率场景;绝缘电阻(IR)≥10^10Ω(25℃、10V直流),抗漏电性能优异,可有效减少电路损耗。

三、封装与物理特性

采用EIA 1812标准封装(英制尺寸:0.18in×0.12in,公制尺寸:4.5mm×3.2mm),典型厚度约1.0mm(具体以官方 datasheet 为准)。端电极采用镍/锡镀层,符合RoHS及无铅要求,适配自动化贴装设备,焊接兼容性好,可兼容常规回流焊/波峰焊工艺。

四、典型应用场景

  1. 开关电源与电力电子:PFC(功率因数校正)电路高压滤波、逆变器高压母线电容;
  2. 医疗设备:高压隔离电路、医用成像设备(如CT/MRI辅助电路);
  3. 工业自动化:高压传感器接口、PLC(可编程逻辑控制器)高压控制模块;
  4. 新能源领域:光伏逆变器、充电桩高压滤波及储能电路;
  5. 通信设备:基站射频高压模块、微波通信电源滤波。

五、品牌与可靠性保障

禾伸堂(IHHEC)作为专业陶瓷电容制造商,该产品通过多项行业可靠性测试:

  • 温度循环测试(-55℃~125℃,循环1000次,容值变化≤±1%);
  • 湿度老化测试(85℃/85%RH,1000h,绝缘电阻衰减≤20%);
  • 耐电压测试(3kV直流,1s,无击穿、无飞弧)。

无极性设计、陶瓷介质稳定性使其具备长寿命(典型>10^6小时),抗振动性能符合工业级标准(振动频率20~2000Hz,加速度1.5g),可适应严苛工况。

六、选型与使用注意事项

  1. 电压降额:高压应用需严格执行降额,避免过压导致介质击穿;
  2. 焊接工艺:回流焊峰值温度控制在260℃以内,避免热冲击损坏端电极;
  3. 存储条件:常温干燥环境(温度≤30℃,湿度≤60%RH),开封后建议12个月内使用;
  4. 电路匹配:C0G材质容值稳定,适合与运算放大器、高精度滤波器等配合;
  5. 安装注意:MLCC无极性,但需确保封装方向与PCB焊盘匹配,避免虚焊。

该产品凭借高压耐受、宽温稳定、低损耗等特性,可有效解决高电压场景下的滤波、耦合及储能需求,是工业控制、新能源等领域的高性价比选择。

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
