FV31X332K202EEG 高压贴片MLCC产品概述
一、产品核心定位与基础参数
FV31X332K202EEG是PSA信昌电陶推出的高压贴片多层陶瓷电容（MLCC），专为中高压电子系统的滤波、耦合、储能场景设计，兼顾小体积与高耐压。核心参数明确：
- 容值：3.3nF（标识“332”，即33×10²pF）；
- 精度：±10%（标识“K”）；
- 额定电压：2kV（标识“202”，即20×10²V）；
- 温度系数：X7R（EIA标准）；
- 封装：1206（英制尺寸）。
该型号属于信昌FV31系列高压MLCC，适配高密度SMT设计，无需额外布局调整。
二、封装与尺寸规格
采用1206贴片封装（公制尺寸3.2mm×1.6mm），典型厚度0.75mm（信昌官方值），引脚间距0.5mm±0.1mm，符合常规SMT产线标准。封装紧凑，可直接兼容1206焊盘设计，适合对空间敏感的高压设备（如光伏逆变器、医疗高压模块）。
三、电气性能与温度特性
3.1 电气性能
- 额定电压稳定性：2kV直流下容值偏差≤±10%，漏电流典型值≤1μA（25℃、额定电压测试），满足高压低损耗需求；
- 交流纹波耐受：可承受1kHz频率下1kV交流纹波（峰值），适配开关电源等含纹波场景；
3.2 温度特性
X7R系数决定工作温度范围**-55℃至+125℃**，容值随温度变化≤±15%（EIA标准），宽温环境下无需额外补偿，适合工业户外、医疗高温模块。
四、典型应用场景
- 工业电源：变频器、开关电源高压母线滤波，抑制共模/差模干扰；
- 新能源：光伏逆变器DC侧滤波、储能变流器高压耦合（适配1500V光伏系统）；
- 医疗设备：高压发生器储能、医用影像设备高压耦合（符合医疗安全规范）；
- 通信基站：高压电源模块滤波去耦，支持基站稳定运行；
- 工业控制：PLC高压输入模块滤波，提升信号抗干扰能力。
五、可靠性与环境适应性
- 焊接可靠性：符合J-STD-020，承受260℃回流焊3次（每次10秒），无开裂、容值衰减；
- 环境耐受：
- 湿热测试：40℃/93%RH下1000小时，性能无明显变化（IEC 60068-2-67）；
- 机械强度：抗弯折≥5mm（IEC 60068-2-21），适配振动场景（如工业变频器）；
- 长期可靠性：125℃/1.5kV下1000小时加速测试，容值偏差≤±5%，漏电流无上升。
六、选型与应用注意事项
- 电压降额：实际工作电压≤1.6kV（额定80%），避免高温下击穿；
- 温度适配：100℃以上环境需预留15%容值余量（高温容值衰减）；
- 焊接工艺：遵循信昌推荐曲线（峰值255-260℃，≤10秒），避免过度加热；
- 存储条件：25℃±5℃、湿度≤60%RH存储，开封后1个月内使用；
- 极性注意：MLCC无极性，但高压下需对齐焊盘，避免电场集中。
该产品通过RoHS、REACH认证，符合绿色设计要求，是高压场景的高性价比选择。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
