C1812X103K202T 贴片多层陶瓷电容(MLCC)产品概述

C1812X103K202T是禾伸堂(IHHEC)针对高压应用场景推出的工业级贴片多层陶瓷电容,兼顾高电压耐受、容值稳定性与紧凑封装,可满足新能源、医疗设备、工业控制等领域的高压电路需求,是传统插件高压电容的高效替代方案。

一、产品核心参数及命名解析

1. 基础参数明细

参数项 规格值 说明 容值 10nF(10×10³pF) 103编码(10→有效数字,3→10³幂次) 精度 ±10%(K档) 符合工业级通用精度要求 额定电压 2kV(直流/交流兼容) 适用于1.5kV以内实际工作电压(降额75%) 温度系数 X7R -55℃~125℃,容值变化±15% 封装 1812(英制) 公制尺寸:4.57mm×3.05mm 品牌 禾伸堂(IHHEC) 台系MLCC主流品牌

2. 命名规则拆解

型号遵循禾伸堂MLCC标准逻辑:

  • C:电容(Capacitor)标识;
  • 1812:封装尺寸(英制180mil×120mil);
  • X:温度系数前缀(对应X7R系列);
  • 103:容值编码(10×10³pF=10nF);
  • K:精度等级(±10%);
  • 202:额定电压编码(20×10²V=2kV);
  • T:高压MLCC系列标识。

二、关键技术特性与优势

1. 高压耐受与降额适配

额定电压2kV的设计覆盖多数工业高压场景(如光伏1500V母线、医疗高压脉冲电路),建议实际工作电压≤1.5kV(降额75%),避免过压导致陶瓷击穿或容值漂移,保障长期可靠性。

2. 稳定的温度性能

X7R是MLCC中中温稳定性最优的类别:

  • 工作温度范围:-55℃~125℃(覆盖工业、医疗设备的极端环境);
  • 容值变化率:±15%以内(无极性电容中,温度对容值影响小,适合滤波、耦合等场景)。

3. 紧凑封装与高密度布局

1812封装体积小(4.57mm×3.05mm),可兼容多数高密度PCB设计,尤其适合新能源、通信设备等对空间要求严格的产品。

4. 高可靠性设计

  • 采用禾伸堂专利多层陶瓷叠层工艺,减少内部应力集中;
  • 符合RoHS无铅标准,焊接温度适配回流焊(峰值260℃±5℃,持续≤10s);
  • 可靠性测试通过:高温负载寿命(THB:85℃/85%RH,2kV下1000h,容值变化≤±10%)、振动测试(10~2000Hz,1.5g加速度,10h无失效)。

三、典型应用场景

C1812X103K202T针对高压需求优化,核心应用包括:

  1. 新能源领域:光伏逆变器DC高压侧滤波、充电桩高压母线滤波、储能系统高压耦合;
  2. 工业控制:变频器高压母线滤波、高压传感器信号耦合、工业机器人高压驱动;
  3. 医疗设备:高压脉冲发生器滤波、医用成像设备高压隔离、生命支持设备高压电源;
  4. 通信设备:基站高压电源滤波、射频功放高压耦合、卫星通信高压电路。

四、选型与使用注意事项

1. 电压降额原则

高压MLCC需严格降额:实际电压≤额定电压的75%(2kV→≤1.5kV),避免过压损坏。

2. 温度范围限制

X7R仅适配-55℃~125℃,若场景温度超出(如≥130℃或≤-60℃),需更换Y5V或NPO系列。

3. 焊接工艺要求

  • 优先回流焊(避免手工烙铁局部过热开裂);
  • 焊接后检查引脚完整性,无虚焊、桥接。

4. 存储条件

未焊接电容需存于常温干燥环境(25℃±5℃,湿度≤60%RH),避免受潮导致焊接爆浆。

五、产品总结

C1812X103K202T以2kV高电压、X7R稳定特性、1812紧凑封装为核心,覆盖多领域高压应用,兼具可靠性与成本效益,是工业级高压电路的可靠选型。

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
