C1808X222K202T 贴片电容产品概述

一、产品基本定位

C1808X222K202T是禾伸堂(IHHEC) 推出的一款高压贴片陶瓷电容,针对工业、医疗、电源等领域的高压电路需求设计,采用X7R介质材料,兼顾容值稳定性与高压耐受能力,适配自动化表面贴装(SMT)生产工艺,可替代传统高压电解电容实现电路小型化。

二、核心参数详细说明

该电容的关键参数可明确拆解为以下核心指标:

  • 容值与精度:标称容值2.2nF(即2200pF),精度标注为“K”,对应±10%误差范围;容值编码“222”遵循陶瓷电容通用规则:前两位为有效数字(22),第三位为倍率(10²),即22×10²=2200pF;
  • 额定电压:直流额定电压2kV,可满足中高压电路的绝缘与耐压需求(交流应用需参考品牌 datasheet 降额曲线,通常峰值电压不超过直流额定值的70%);
  • 温度系数:X7R介质,工作温度范围为-55℃至+125℃,在此区间内容值变化率≤±15%,稳定性优于Y5V等高压电容;
  • 封装与尺寸:采用1808英制贴片封装(长度0.18英寸/4.57mm,宽度0.08英寸/2.03mm),厚度1.6mm,适配常规SMT设备的贴装精度要求;
  • 介质类型:X7R陶瓷介质,兼具较高容值密度与温度稳定性,区别于NP0(温度稳定性极高但容值密度低)或Y5V(容值密度高但温度稳定性差)介质。

三、关键特性与优势

  1. 高压耐受能力:2kV直流额定电压覆盖多数中高压电路场景,无需并联多颗低压电容即可实现目标容值,简化电路设计并缩小体积;
  2. 宽温稳定性:X7R介质的温度特性使其在极端环境(如工业高温、低温户外)下仍能保持容值稳定,避免因温度变化导致电路性能偏移;
  3. 贴片工艺适配:1808封装与1.6mm厚度符合SMT自动化生产要求,可兼容常规回流焊、波峰焊工艺(回流焊最高温度≤260℃/10秒),提升生产效率;
  4. 环保与可靠性:符合RoHS、REACH等环保标准,无铅无卤;禾伸堂通过ISO9001、IATF16949等质量体系认证,产品经过高温老化、电压寿命测试(如1000小时2kV直流加载),确保长期使用可靠性;
  5. 低损耗特性:X7R介质的损耗角正切值(tanδ)≤0.015(1kHz下),适合高压滤波、EMI抑制等低损耗场景。

四、典型应用场景

该电容主要适用于以下高压电路场景:

  • 开关电源高压侧:AC-DC电源的高压滤波、EMI抑制,替代传统电解电容以缩小体积;
  • LED驱动电源:高压线性驱动电路中的滤波、耦合,提升电源效率与稳定性;
  • 医疗设备:如高压发生器、诊断设备的高压模块滤波,满足医疗级可靠性要求;
  • 工业控制:PLC、变频器等设备的高压信号耦合、噪声抑制,适应工业环境的宽温与振动需求;
  • 通信设备:基站电源的高压滤波,降低电磁干扰对信号传输的影响;
  • 新能源领域:充电桩、光伏逆变器的高压滤波,适配户外宽温环境。

五、品牌与质量保障

禾伸堂(IHHEC)作为专业陶瓷电容制造商,拥有超过20年的高压电容研发与生产经验,其产品广泛应用于汽车电子、工业控制、医疗等高端领域。C1808X222K202T在生产过程中经过严格的参数分选(容值、耐压、绝缘电阻等),每批次产品均附带合格证明,可满足客户的质量追溯需求。

六、注意事项

  1. 电压降额:交流应用需按品牌 datasheet 进行电压降额,避免击穿;
  2. 焊接温度:回流焊温度需控制在X7R介质耐受范围内,避免高温导致容值漂移;
  3. 存储条件:建议存储于温度-40℃至+60℃、湿度≤60%的环境中,开封后12个月内使用,避免受潮影响绝缘性能。

该产品凭借高压耐受、宽温稳定与贴片适配性,成为中高压电路小型化设计的优选元件。

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
