华新科0805N221J500CT多层陶瓷电容器(MLCC)产品概述

华新科(Walsin)0805N221J500CT是一款高频低损耗型多层陶瓷电容器(MLCC),专为对容值稳定性、温度特性要求严苛的电子电路设计,核心参数覆盖220pF容值、±5%精度、50V额定电压及NP0(COG)温度系数,适配0805(2012公制)标准表面贴装封装。

一、产品基本属性与型号解析

该产品型号遵循华新科MLCC编码规则,各字符含义清晰:

  • 0805:英制封装尺寸(0.08英寸×0.05英寸),对应公制2012(2.0mm×1.2mm);
  • N:温度系数标识,对应国际标准NP0(COG);
  • 221:容值编码(22×10¹=220pF);
  • J:精度等级(EIA标准,±5%);
  • 500:额定电压(50×10⁰=50V DC);
  • CT:封装细节及生产批次后缀(具体参考华新科官方 datasheet)。

产品类别为Class 1型MLCC,属于高频应用核心元件。

二、核心电气性能参数详解

  1. 容值与精度:标称容值220pF,精度±5%,工作温度范围内容值漂移极小;
  2. 额定电压:50V DC(直流额定),交流应用需按80%降额设计(≤40V);
  3. 温度系数:NP0(COG),标准范围0±30ppm/℃(-55℃~+125℃),温度稳定性最优;
  4. 损耗特性:典型损耗角正切tanδ≤0.15%(1kHz、25℃),高频下损耗低;
  5. 工作温度范围:-55℃~+125℃(华新科Class 1 MLCC标准范围)。

三、封装与物理特性

0805封装为行业通用表面贴装设计,物理尺寸(典型值):

  • 长度:2.0±0.2mm;
  • 宽度:1.2±0.2mm;
  • 厚度:0.8±0.1mm(端电极高度不计);
  • 端电极:镍-锡(Ni-Sn)镀层,适配回流焊、波峰焊工艺,焊接可靠性高。

封装紧凑,适合高密度PCB布局,满足小型化设备需求。

四、温度系数与稳定性优势

NP0(COG)是Class 1电容的核心优势:

  • 容值稳定:温度变化对容值影响可忽略,避免电路性能波动(如振荡频率偏移);
  • 高频特性优异:谐振频率>1GHz,适合100MHz以上射频、微波电路;
  • 损耗极低:相比Class 2(如X7R)电容,损耗仅为其1/10~1/5,减少信号失真。

五、典型应用场景

基于核心性能,该产品广泛应用于:

  1. 射频电路:蓝牙、WiFi、5G模块的滤波器、阻抗匹配网络;
  2. 振荡电路:晶体振荡器(XO)、压控振荡器(VCO)的谐振电容;
  3. 通信设备:基站、无线路由器的高频前端;
  4. 测试仪器:示波器、信号发生器的校准电路;
  5. 工业控制:温度稳定性要求高的传感器接口电路。

六、品牌与可靠性说明

华新科是全球领先被动元件制造商,该产品符合:

  • 环保标准:RoHS 2.0、REACH;
  • 可靠性测试:高温存储(125℃/1000h)、温度循环(-55℃~+125℃/1000次)、湿度偏压(85℃/85%RH/50V/1000h),失效率低;
  • 供应稳定性:量产能力强,适合大规模量产。

七、选型与使用注意事项

  1. 电压降额:实际工作电压≤40V DC,避免过压击穿;
  2. 焊接工艺:回流焊峰值温度245℃±5℃,时间≤10s,避免手工焊过热开裂;
  3. 存储条件:开封前存储于25℃±5℃、湿度≤60%环境,开封后12个月内使用;
  4. 静电防护:MLCC为静电敏感元件,需ESD防护(防静电包装、工作台接地)。

该产品平衡了稳定性、高频性能与封装密度,是高性能电子电路的优选Class 1 MLCC。

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
