0402CG221J500NT — 0402 220pF C0G ±5% 50V 贴片电容(风华)产品概述

一、产品简介

0402CG221J500NT 为风华(FH)系列的多层陶瓷贴片电容(MLCC),额定电容值 220pF,精度 ±5%(J),额定直流电压 50V,介质为 C0G(NP0)类温度系数,封装为 0402(约 1.0mm × 0.5mm)。该型号定位于需要高稳定性、低损耗与低温漂的高频与精密模拟场合。

二、主要性能特点

  • 温度稳定性好:C0G(近零型)介质在整个额定温度范围内电容变化极小,适合对频率/相位敏感的电路。
  • 低介质损耗、高 Q 值:在射频和高频应用中表现优异。
  • 低电压依赖性:相比高介电常数陶瓷,C0G 在加偏压下电容量变化微弱。
  • 小尺寸表面贴装:0402 封装利于高密度 PCB 布局与体积受限设计。

三、典型电气与机械参数(建议以出厂数据表为准)

  • 标称电容:220pF
  • 容差:±5%(J)
  • 额定电压:50V DC
  • 介质:C0G(NP0)
  • 封装:0402(约 1.0 × 0.5 mm)
  • 温度系数:C0G(近似 0 ppm/°C,温度稳定性优异)
    (以上参数应以风华官方数据表和检验报告为准)

四、典型应用场景

  • 高频滤波、谐振电路与走线终端阻抗匹配
  • 时钟、振荡器与定时电路的旁路/耦合电容
  • 精密模拟前端、传感器接口与 ADC/DAC 输入滤波
  • 射频前端和高频 PCB 走线的去耦与旁路

五、PCB 布局与焊接建议

  • 推荐采用厂家提供的焊盘尺寸与推荐图形,保证焊接可靠性与热膨胀匹配。
  • 0402 尺寸小,注意防止“立碑”现象(tombstoning):两端焊盘对称、焊膏量匹配有助于减少风险。
  • 回流焊工艺按 JEDEC 推荐曲线进行,最高回流温度一般不超过 260°C;如需波峰或特殊工艺,请向厂商确认。
  • 焊接后尽量避免重复高温回流影响电容特性。

六、可靠性、合规与采购建议

  • 风华为常见主流供应商之一,该型号通常满足 RoHS 等环保要求;是否具备 AEC-Q200 等汽车级认证需以具体型号资料为准。
  • 批量采购时建议索取最新数据表、可靠性报告(如温度循环、湿热、冲击、振动等测试)与样品验证。
  • 如需更高电压或更小电容偏差,可选用相近系列或咨询厂家定制方案。

七、封装与订购信息

  • 常见包装形式为卷装(Tape & Reel),卷装数量视包装规格而定(常见为 3k/5k/10k 等)。
  • 型号解读(示例):0402 CG 221 J 500 NT —— 0402 封装 / C0G / 221=220pF / J=±5% / 500=50V / NT=包装或工厂内部代码(具体含义请以风华官方物料编码为准)。

八、选型注意事项

  • 若电路对温度漂移和频率稳定性要求极高,C0G 为优先选择;若需更大电容值或体积限制更严,可考虑其他介质但需注意温漂与偏压效应。
  • 在高湿或高温环境使用前,应核查厂方的环境测试与寿命数据。
  • 如涉及关键或安全类应用,建议进行电气老化与现场验证。

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
