C1812X102K202T 贴片多层陶瓷电容(MLCC)产品概述

一、产品型号与核心身份识别

C1812X102K202T是禾伸堂(IHHEC) 推出的高压贴片多层陶瓷电容(MLCC),型号各部分含义清晰:

  • C:代表电容类型;
  • 1812:英制封装规格(对应公制4532,尺寸4.5mm×3.2mm);
  • X7R:介质温度系数(核心特性标识);
  • 102:容值编码(10×10²pF=1nF);
  • K:容值精度±10%;
  • 202:直流额定电压2kV;
  • T:工艺/封装细节标识(如无铅端电极优化)。

该产品针对中高压电子电路设计,兼顾小体积与高压耐受能力。

二、关键电气性能参数

1. 容值与精度

标称容值1nF(1000pF),容值偏差严格控制在**±10%** 以内,满足常规电路对容值一致性的要求,无需额外校准。

2. 额定电压

直流额定电压2kV,可承受短期脉冲过压(≤2.5kV),适合高压环境下的滤波、耦合等场景,避免过压击穿风险。

3. 温度特性

采用X7R铁电陶瓷介质,工作温度范围为**-55℃至+125℃**,温度变化范围内容值波动≤±15%——既优于Y5V等低成本介质的温度稳定性,又比NP0介质具有更高的容值密度,平衡了性能与成本。

4. 附加性能

  • 低损耗:典型值≤0.5%@1kHz,适合高频滤波或信号耦合;
  • 低漏电流:≤1μA@2kV/25℃,满足低功耗电路的漏电控制要求。

三、封装与材料特性

1. 封装设计

1812贴片封装(无引线结构),尺寸紧凑(4.5mm×3.2mm×1.2mm典型厚度),兼容自动贴装(SMT)设备,可大幅提升PCB布局密度,适合小型化电子设备。

2. 介质与端电极

  • 介质:X7R陶瓷,兼顾容值稳定性与耐高压性能;
  • 端电极:多层金属结构(镍底层+无铅锡层),焊接可靠性高,耐湿热老化(符合RoHS2.0环保标准),长期使用无脱落风险。

四、典型应用场景

该产品凭借高压耐受、宽温稳定、小体积特性,广泛应用于:

  1. 开关电源高压侧:AC-DC转换电路的高压滤波、LED驱动电源的输出耦合;
  2. 新能源领域:光伏逆变器直流高压侧滤波、电动汽车充电模块的高压旁路;
  3. 工业自动化:高压传感器模块、执行器的信号滤波,保障工业环境下的信号稳定性;
  4. 医疗设备:高压隔离电路、诊断设备的滤波组件(满足医疗级可靠性要求)。

五、可靠性与环境适应性

  1. 品质认证:符合ISO9001质量管理体系,通过UL、VDE等国际安全认证,满足工业级应用标准;
  2. 环境耐受:耐振动(10~2000Hz,1.5g加速度)、耐湿热(J-STD-020标准),可适应恶劣工况;
  3. 寿命特性:额定条件下平均无故障时间(MTBF)≥10⁶小时,长期可靠性有保障。

六、品牌与应用价值

禾伸堂(IHHEC)作为专业被动元器件制造商,在高压MLCC领域拥有成熟技术积累,产品覆盖全电压、容值范围。C1812X102K202T可有效简化高压电路设计复杂度,提升系统稳定性,是中高压电子设备的优选被动元件。

该产品以高压耐受、宽温稳定、小体积为核心优势,适配多场景需求,为电子系统提供可靠的电容支撑。

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
