FM43N223J631EFG 产品概述

一、产品简介

FM43N223J631EFG 为 PSA(信昌电陶)系列贴片多层陶瓷电容(MLCC),标称容量 22nF(223),公差 ±5%(J),额定直流电压 630VDC,温度特性为 C0G(俗称 NP0)。封装为 1812(约 4.6 × 3.2 mm),适用于对容量稳定性和低损耗有较高要求的高压电路场合。

二、主要电气参数

  • 容值:22 nF(223)
  • 容量公差:±5%(J)
  • 额定电压:630 V DC
  • 温度系数:C0G(NP0),温度漂移接近 0 ppm/°C(温度稳定性极佳)
  • 工作温度范围:典型 -55 ℃ 至 +125 ℃(请参照厂方规格书确认)
  • 封装:1812(SMD,常见尺寸约 4.6 × 3.2 mm)

三、产品亮点与优势

  • 极高的温度稳定性:C0G/NP0 介质使电容在宽温度范围内容量变化极小,适合高精度滤波、定时与谐振电路。
  • 低损耗、低介电吸收:适用于高频信号处理和脉冲应用,能保持信号完整性。
  • 630V 高压等级:适合高压耦合、直流隔离、开关电源或高压驱动电路中使用。
  • SMD 封装 1812:既保证电压与功率处理能力,也便于自动化贴装与批量生产。

四、典型应用场景

  • 开关电源输入/输出滤波与阻尼电路(高压侧)
  • 高压耦合/去耦与直流隔离电路
  • 脉冲整形、测量与采样电路(需稳定电容量)
  • LED 驱动、电机驱动与逆变器的高压滤波或能量缓冲
  • 医疗、航空、工业控制等对稳定性和可靠性要求高的领域

五、选型与使用建议

  • DC 偏置效应:相较于高介电常数陶瓷(如 X7R),NP0 对直流偏置的容量衰减极小,选型时仍建议在目标工作电压下验证实际容量。
  • 冗余/降额:在关键电路可考虑适度降额(例如不超过额定电压的 80–90%)以提升可靠性。
  • 温度与频率:C0G 在温度和频率变化下表现稳定,适合高精度频率相关电路。
  • 机械应力:贴片电容对 PCB 弯曲和焊接应力敏感,建议在 PCB 布局时留出一定焊盘与过孔缓冲区,并避免在接近边缘处施加应力。

六、封装与焊接说明

  • 1812 尺寸,适用于自动贴装与回流焊工艺。建议按 J-STD-020 回流曲线进行焊接,最大回流温度参照厂方推荐(典型上限 260 ℃)。
  • 对潮湿敏感器件,请参考器件的湿敏等级(MSL)并在必要时进行预烘烤处理。
  • 焊盘设计应遵循厂家推荐焊盘尺寸以控制应力并获得可靠焊点。

七、质量与合规

PSA(信昌电陶)出厂产品通常经过电气性能、外观及可靠性测试;对 RoHS 等环保要求请向供应渠道索取相应合规证书与试验报告,以满足项目考核需求。

八、采购与包装

  • 常见包装方式为卷带(Tape & Reel),便于 SMT 自动化生产。
  • 购买时请确认完整料号、批次与出厂测试报告;大量使用场景建议取得样品并在目标电路中做温度、电压和频率下的性能验证。

总结:FM43N223J631EFG(22nF ±5% 630V C0G 1812)是一款面向高压与高稳定性场合的 MLCC,适合需低温漂、低损耗和高可靠性的工业与电力电子应用。购买和使用时建议参考厂方规格书并进行实际工作条件下的验证。

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
