C1808N102J302T 高压NP0贴片MLCC产品概述

一、产品定位与核心价值

C1808N102J302T是禾伸堂(IHHEC) 推出的一款高压、高频稳定型贴片多层陶瓷电容(MLCC),针对对容值精度、温度稳定性、耐压性能要求严苛的应用场景设计。核心价值在于平衡了3kV直流额定电压与NP0级温度稳定性,同时保持贴片封装的小型化优势,解决了传统高压电容体积大、稳定性差的痛点,是高频高压电路的高性价比选择。

二、关键参数深度解析

该产品的核心参数可通过型号与官方规格对应,关键信息如下:

  1. 容值与精度:标称容值1nF(1000pF),容差为**±5%(J档)**——NP0材料的固有高精度特性,适合对容值一致性要求高的耦合、滤波电路;
  2. 额定电压:3kV直流(DC)——型号中“302”对应30×10²=3000V,为该产品的核心耐压指标(注:MLCC通常不推荐直接使用交流电压,若需交流需按1/√2降额);
  3. 温度系数:NP0(Class 1)——EIA标准中,NP0的温度系数范围为**±30ppm/℃**,在-55℃~+125℃宽温范围内容值变化≤0.3%,且损耗角正切(tanδ)极低(典型值≤0.001),高频特性优异;
  4. 封装尺寸:1808英制贴片——对应公制尺寸约4.57mm×2.03mm×1.2mm(典型厚度),兼容常规回流焊工艺,适配中小尺寸PCB设计;
  5. 端电极:采用镍-锡(Ni/Sn) 端电极,符合RoHS环保要求,焊接可靠性高,不易出现虚焊。

三、封装与结构设计特点

  1. 高压适配结构优化:针对3kV耐压需求,采用细间距多层电极+高密度陶瓷介质设计,既保证容值密度,又通过电极边缘钝化处理减少电场集中,提升击穿电压可靠性(典型击穿电压≥4.5kV);
  2. 1808封装优势:相比插件高压电容(如轴向电容)体积缩小50%以上,适合现代电子设备的小型化趋势;封装引脚间距合理,回流焊时不易出现立碑、桥接等缺陷;
  3. NP0材料特性:NP0属于非极性陶瓷材料,无压电效应,适合高频信号传输(如射频、微波频段),且耐电流能力优于普通高压电容,可承受瞬时脉冲电压冲击(如1.5倍额定电压的脉冲)。

四、典型应用场景

结合产品的高压、高频稳定特性,主要应用于以下领域:

  1. 射频/微波通信:基站功率放大器的高压耦合电容、微波发射模块的滤波电容,利用NP0的低损耗保证信号完整性;
  2. 医疗电子:X光机、超声设备的高压电源滤波电容,需稳定容值保障输出精度;
  3. 工业测试仪器:示波器探头的高压分压电容、PLC的高压输入电路,耐受工业环境的宽温与脉冲电压;
  4. 商用车电子:车载充电系统的高压滤波、高压传感器电路,适配商用车的宽温工作环境;
  5. 航空航天配套:(若通过军规认证)卫星通信、机载设备的高压信号处理电路,依赖宽温稳定性。

五、品牌与可靠性优势

禾伸堂(IHHEC)作为国内MLCC领域的专业制造商,该产品具备以下可靠性优势:

  1. 严苛测试验证:通过高温寿命测试(125℃×1000h)、湿度负载测试(85℃/85%RH×1000h)、耐压测试(3.3kV DC,1s),满足工业级可靠性要求;
  2. 环保合规:符合RoHS 2.0、REACH等国际环保标准,无铅无镉,适配出口市场;
  3. 供货稳定性:针对高压MLCC的产能布局完善,可支持批量订单与定制化需求(如容差调整、封装优化)。

该产品凭借高压、高稳定、小型化的综合优势,已成为工业控制、医疗电子等领域的主流高压贴片电容选择。

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
