0402B333K500NT 产品概述

一、产品简介

0402B333K500NT 为风华(FH)系列贴片多层陶瓷电容(MLCC),标称容量 33 nF,容差 ±10%,额定电压 50 V,介质等级 X7R,封装 0402(约 1.0 mm × 0.5 mm)。该型号面向高密度贴装场景,兼顾体积与容值,适用于电源去耦、旁路与一般滤波场合。

二、主要参数与特性

  • 容值:33 nF(0.033 μF),公差 ±10%
  • 额定电压:50 V DC
  • 介质:X7R(温度范围 -55 ℃ 至 +125 ℃,在该温区内电容变动在 ±15% 以内)
  • 封装:0402(片式超小型,适合自动贴装)
  • 电气特性:低等效串联电阻(ESR)和低等效串联电感(ESL),适合高频去耦与稳压瞬态响应需求
  • 环保与可靠性:常规符合无铅、RoHS 要求(以出厂检验报告为准)

三、性能说明与设计注意事项

  • 温度特性:X7R 为类 II 介质,温度稳定性好于 Z5U,但仍存在随温度变化的电容漂移,设计时应考虑 ±15% 的温度贡献。
  • 直流偏压效应:在施加直流偏压时,电容值会下降(特别是在体积小、容值较大的器件上更明显),实际工作电容可能低于标称值。
  • 老化与时间漂移:陶瓷介质存在随时间的老化效应,初期可能出现一定的容量衰减,应在精密电路设计时预留裕量。
  • 精密测量与定时场合建议选用 C0G/NP0 等一类介质,不建议用 X7R 作高精度定时元件。

四、典型应用场景

  • 电源去耦与旁路滤波(PCB 上靠近集成电路供电引脚)
  • 开关电源输出滤波与 EMI 滤波网络
  • 音频/模拟电路中作为耦合或退耦元件(非高精度定时)
  • 移动设备、消费电子、物联网模组等高密度贴片场合

五、封装、焊接与储存建议

  • 包装:通常采用卷带(tape & reel)方便 SMT 自动贴装,具体包装方式和数量请参考厂家出货单。
  • 焊接:按业界回流焊工艺执行,使用厂家推荐的回流曲线;避免超温与多次高温回流带来的性能损伤。
  • 贴装注意:0402 封装尺寸小,搬运与回流过程中应避免机械应力和焊盘不当设计导致的开裂。
  • 储存:按湿敏等级(MSL)管理,开盘后按回流次数和时效要求使用,必要时进行烘烤处理以防潮湿吸附。

六、选型与可靠性建议

  • 若电路对电容绝对值稳定性要求较高,应在选型时考虑 DC 偏压、温度系数和老化共同影响,并适当降额使用(例如将工作电压控制在额定电压的 50%–80% 范围内,具体视应用敏感度而定)。
  • 对于高频去耦,建议并联不同封装或不同介质的电容以互补 ESR/ESL 特性。
  • 采购时请索取风华的完整规格书与可靠性测试报告,确认回流曲线、湿敏等级和放电/耐压等关键参数,以满足量产与认证需求。

本产品以小封装与较大容值的组合,提供在有限 PCB 面积内良好的去耦与滤波能力,适合消费电子与工业控制等多种应用场景。若需详细电参数曲线(温度特性、DC bias 曲线、频率响应等)或样品测试结果,建议联系供应商索取完整数据手册。

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
