0402B182K500NT 产品概述

一、产品简介

0402B182K500NT 为风华(FH)生产的一款贴片多层陶瓷电容(MLCC),额定电容值 1.8nF(182 = 1800pF),公差 ±10%(K),额定电压 50V(500),介质材料 X7R,封装尺寸为 0402(约 1.0mm × 0.5mm)。该器件为表面贴装型,常见于高密度电路板的旁路、滤波、耦合和谐振等应用,兼容无铅回流焊工艺,适合消费类电子、通信、便携式设备和工业电子等场景使用。

二、主要性能参数

  • 容值:1.8nF(1800pF)
  • 公差:±10%(K)
  • 额定电压:50V DC
  • 介质:X7R(温度范围 -55℃ 至 +125℃,按 X7R 规范温漂容值变化通常在相应温区内允许一定范围的变化)
  • 封装:0402(近似外形尺寸 1.0mm × 0.5mm;厚度视具体系列而定,常见约 0.4–0.5mm,详见厂方数据手册)
  • 包装:常见为卷带(Tape & Reel),NT 为厂方包装/版本代号(具体含义以风华官方资料为准)
  • RoHS:符合无铅环保要求(需按采购时确认具体合规证书)

三、产品特性与优点

  • 体积小、密度高:0402 尺寸满足高密度贴片需求,有利于设备小型化与轻量化设计。
  • 稳定的温度特性:X7R 介质在-55℃到+125℃范围内能够保持相对稳定的电容量,适合一般工业和消费电子环境。
  • 良好的高频特性:MLCC 本身具有低等效串联电阻(ESR)与低等效串联电感(ESL),适用于电源去耦和高频旁路。
  • 工艺兼容:适用于标准无铅回流焊(建议遵循厂方回流温度曲线,峰值温度通常≤260℃),便于自动化贴装与回流焊接流程。
  • 成本与可靠性平衡:X7R 在容量/体积/成本之间提供良好折衷,适合需要中等精度与稳定性的应用。

四、典型应用场景

  • 电源去耦/旁路:滤除电源噪声、稳定供电电压、改善瞬态响应。
  • EMI 抑制与滤波网络:与电感、阻容网络配合形成低通/高通滤波器。
  • 耦合与旁路:在模拟信号路径做耦合或交流旁路(注意 X7R 的电容随温度/偏压可能有变化,重要耦合场合优先考虑 C0G/NP0)。
  • 高频电路与射频前端(作为旁路或去耦):在不要求极高稳定性的高频场合使用。
  • 便携式与消费类电子:手机、无线设备、可穿戴设备等对小尺寸贴片电容需求较大。

五、选型与应用注意事项

  • 温度与频率响应:X7R 在高温或高频条件下的实际电容量会与标称值存在偏差,设计时应考虑温漂、频率依赖和直流偏置影响(DC bias effect)。
  • 直流偏置(DC bias):高介电常数材料在施加较高偏压时电容可能下降,若电路对电容值敏感,应在典型工作电压下验证实际电容值或考虑更稳定的介质。
  • 焊接工艺:建议遵循厂方回流曲线,控制回流峰值温度和时间,避免超温或重复加热导致失效。合理的焊膏印刷量与回流曲线可减少“立碑”(tombstoning)等贴装缺陷。
  • 机械应力:0402 体积小但对过大的弯曲与应力敏感,PCB 设计与装配时应避免过度弯曲或板端剪切应力。
  • 汽车/高可靠性要求:若用于汽车或安全关键系统,请明确器件是否通过 AEC-Q200 或其他相应认证;若无相关认证,应在项目早期与厂商确认。

六、封装与采购信息

  • 封装形式:0402 表面贴装
  • 包装方式:卷带(Tape & Reel),方便 SMT 贴片机自动化生产
  • 型号解读示例:0402B182K500NT —— 0402(封装) / 182(1.8nF) / K(±10%) / 500(50V) / NT(厂方包装/版本代号,具体含义以厂家资料为准)
  • 采购建议:批量采购前建议索取样品并在目标电路环境(温度、频率、工作电压)下做实际测量验证;同时确认交期、放电/老化测试要求及相关合规证书。

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
