FV43N221J102ECG 贴片陶瓷电容(MLCC)产品概述

一、产品基本信息

FV43N221J102ECG是信昌电陶(PSA) 推出的一款Class I型贴片多层陶瓷电容(MLCC),采用1812英制封装(对应公制尺寸约4.5mm×3.2mm),适配自动化表面贴装工艺,可直接集成于各类电子设备的PCB板中。该产品定位于高压、高稳定场景,兼顾小型化与性能可靠性,是工业级、通信级电路的常用核心元件。

二、核心电气参数

该电容的关键参数清晰明确,可精准匹配特定应用需求:

  • 容值规格:标称容值220pF,采用行业通用3位编码(221)表示(前两位为有效数字,第三位为10的幂次,即22×10¹=220pF);
  • 精度等级:容值精度±5%,对应电容行业J档精度标准,适用于对容值一致性要求较高的电路;
  • 额定电压:直流额定电压1kV,可稳定承受高压负载,避免击穿风险;
  • 温度系数:采用C0G(原NP0) 温度系数,属于Class I型电容的典型特性,温度系数≤±30ppm/℃,在-55℃至+125℃宽温范围内容值漂移极小;
  • 封装尺寸:1812封装,厚度符合MLCC常规设计,适配多数PCB布局,兼顾容量与空间利用率。

三、关键技术特性

1. 超宽温下的容值稳定性

C0G温度系数是该电容的核心优势:相比Class II型电容(如X7R、Y5V),其容值随温度变化的漂移量可忽略不计。例如,在-40℃至+85℃的常规工作温区,容值变化不足0.1%,可确保电路在极端环境(如工业高温、低温户外)下性能一致,避免信号失真或功能异常。

2. 高耐压与绝缘性能

1kV直流额定电压设计,配合PSA成熟的陶瓷介质配方与多层叠层工艺,具备优异的绝缘电阻(≥10¹⁰Ω),可有效抑制漏电流。即使在高压脉冲场景下,也能保持稳定的电气性能,满足高压电源滤波、EMI抑制等需求。

3. 低损耗与高频适应性

Class I型电容的损耗角正切(tanδ)极低(≤0.001),在1GHz以上射频频段仍能保持低损耗。这一特性使其适合振荡电路、射频匹配网络等高频应用,减少信号能量损耗,提升通信设备的信号传输质量。

4. 贴片封装的兼容性

1812封装体积适中:既避免了0402等小封装的容量限制,又比2220等大封装更节省PCB空间;同时适配自动化贴装设备,支持批量生产中的高效作业,降低人工成本。

5. 环保与可靠性

产品符合RoHS2.0、REACH等国际环保指令,不含铅、镉等有害物质;出厂前经过严格可靠性测试(温度循环、湿度-温度偏压、焊接热冲击等),可在长期使用中保持性能稳定,降低设备维护成本。

四、典型应用场景

该电容的特性使其适用于多个对稳定性、耐压性要求较高的领域:

  1. 射频与微波通信:基站射频前端、雷达系统、卫星通信模块中的滤波、振荡、阻抗匹配电路;
  2. 高压电源系统:工业开关电源、医疗设备电源、新能源充电桩的EMI滤波、高压端去耦电路;
  3. 精密测量仪器:示波器、信号发生器、频谱分析仪的信号调理电路;
  4. 汽车电子:车载通信系统、胎压监测模块(TPMS)的高频电路(适应车载温变与振动);
  5. 工业控制:PLC、伺服驱动器的电源滤波与信号滤波电路(稳定适配工业现场环境)。

五、质量保障与合规性

作为信昌电陶的成熟产品,FV43N221J102ECG遵循IEC 60384-1、JIS C 5101等国际标准,全程质量管控:

  • 陶瓷介质采用高纯度配方,确保温度系数一致性;
  • 多层叠层工艺精度控制在微米级,容值偏差符合±5%要求;
  • 100%出厂耐压测试与容值分选,每颗电容性能达标;
  • 提供SGS报告、RoHS证书等完整合规文件,满足客户认证需求。

该产品凭借高稳定、高耐压、低损耗等特性,成为高压高频电路的优选元件,可有效提升设备的可靠性与性能表现。

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
