FV42N220J302ECG 高压贴片电容产品概述

FV42N220J302ECG是PSA信昌电陶推出的一款高压多层陶瓷贴片电容(MLCC),专为需要高耐压、稳定容值的电路场景设计,核心参数覆盖22pF容值、3kV额定电压及C0G温度系数,封装采用1808英制规格,兼具小型化与高性能特性。

一、产品基本信息

该型号属于信昌电陶高压C0G系列MLCC,型号命名对应关键参数:

  • 「FV42」为系列标识(高压精密陶瓷电容系列);
  • 「N220」表示标称容值22pF(前两位为有效数字,第三位为10^0倍);
  • 「J」代表容值精度±5%;
  • 「302」对应额定直流电压3kV(30×10^2 V);
  • 「ECG」为封装及材质代码(1808封装+C0G陶瓷材质)。

产品采用无引线贴片结构,适配自动化贴装工艺,适合高密度PCB布局,可满足小型化电子设备的性能需求。

二、关键技术参数

参数项 典型值/规格 标称容值 22pF 容值精度 ±5%(J级) 额定直流电压 3kV(DC) 温度系数 C0G(NP0,≤±30ppm/℃) 封装规格 1808英制(4.57mm×2.03mm) 工作温度范围 -55℃ ~ +125℃ 损耗角正切(tanδ) ≤0.15%(1kHz,25℃) 绝缘电阻(IR) ≥10^10 Ω(25℃,100V DC) 厚度 约1.5mm(典型值)

注:以上参数符合IEC 60384-14及行业通用标准,具体以信昌电陶官方 datasheet 为准。

三、核心性能特点

  1. 高耐压稳定性:3kV额定电压覆盖多数中高压电路需求,降额使用可兼容瞬时电压波动场景;
  2. 容值温度稳定性:C0G(NP0)材质温度系数极小,容值随温度变化可忽略,适合精密测量与高频电路;
  3. 低损耗特性:低tanδ减少信号能量损耗,提升电路效率,尤其适配射频振荡、滤波等高频应用;
  4. 无直流偏置效应:与X7R/X5R等材质不同,C0G电容容值不受直流偏置电压影响,无需额外补偿;
  5. 小型化封装:1808封装体积紧凑,适配小型化电子设备的高密度设计;
  6. 高可靠性:经过高温存储、温度循环、振动冲击等严苛测试,抗环境应力能力强,适合工业/医疗等 harsh 场景。

四、典型应用场景

  1. 高压滤波电路:开关电源、逆变器的高压侧滤波(如AC-DC电源的高压整流后滤波);
  2. 高频振荡电路:射频(RF)电路的LC振荡、锁相环(PLL)的参考振荡;
  3. 精密测量设备:示波器、信号发生器、频谱分析仪的高压信号调理模块;
  4. 工业控制电路:高压电机驱动、PLC的高压输入输出模块;
  5. 医疗设备:某些医疗仪器(如X光机高压模块、除颤器辅助电路)的稳定电容;
  6. 汽车电子:高压电池管理系统(BMS)的高压滤波、车载充电机(OBC)的高压侧电路。

五、封装与可靠性说明

  1. 封装细节:1808英制贴片封装,电极采用银钯合金材质,焊接兼容性好(适配无铅回流焊);尺寸公差为长±0.2mm、宽±0.2mm,厚度±0.1mm;
  2. 可靠性测试:通过以下标准测试:
    • 高温存储(125℃,1000h);
    • 温度循环(-55℃~125℃,1000次);
    • 湿度负荷(85℃/85%RH,1000h);
    • 振动冲击(10~2000Hz,加速度2g);
  3. 储存要求:常温干燥环境(温度25℃±5℃,湿度≤60%RH),储存期12个月,开封后需尽快使用(避免受潮影响焊接性能)。

六、选型与使用注意事项

  1. 耐压降额:建议实际工作电压不超过额定电压的80%(≤2.4kV),延长产品寿命并提升可靠性;
  2. 焊接工艺:采用回流焊时,温度曲线需符合MLCC规范(峰值温度≤245℃,时间≤30s),避免过高温度导致陶瓷开裂;
  3. 静电防护:MLCC对静电敏感,操作时需佩戴防静电手环/手套,设备接地,避免静电击穿;
  4. 机械应力:焊接后避免过度弯曲PCB,防止电容引脚与陶瓷体开裂;
  5. 容值匹配:根据电路阻抗、频率需求选择容值,C0G无偏置效应,无需因直流电压调整容值。

FV42N220J302ECG凭借高耐压、稳定容值及小型化优势,在中高压精密电路中具有广泛适用性,是工业控制、医疗设备及射频领域的可靠选择。

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
