0402X105K160NT — 0402 1µF ±10% 16V X5R 贴片电容产品概述

一、产品简介

0402X105K160NT 为风华(FH)生产的一款多层陶瓷贴片电容(MLCC),额定电压 16V,标称电容 1µF,公差 ±10%,温度特性 X5R,封装尺寸为 0402(1005 公制,约 1.0mm × 0.5mm)。该系列针对高密度 SMT 组装与去耦、滤波等常见电路需求,兼具体积小、寄生参数低和良好可靠性。

二、主要电气性能与特性

  • 电容值:1.0 µF(标称)
  • 公差:±10%(K)
  • 额定电压:16 V DC
  • 温度特性:X5R(工作温度范围通常为 -55°C ~ +85°C,温度引起的容值变化在规格范围内)
  • 封装:0402(1005)
  • 特点:体积小、ESR/ESL 低、适合高频去耦与稳压滤波

请注意:Class II 材料(如 X5R)存在明显的直流偏置效应,即在施加直流电压或高温时实际电容可能下降,尤其在小尺寸封装中更明显。建议在样片测试中评估在目标工作电压与温度下的实际容值。

三、典型应用场景

  • 电源去耦与旁路:为 IC、电源模块提供瞬态电流支持
  • 输入/输出滤波:DC-DC 转换器输入输出滤波、LDO 输出旁路
  • 移动设备与便携式电子:空间受限的消费类电子产品
  • 工业与物联网终端:对体积、成本有严格要求的电路板设计

(如需用于汽车或关键安全系统,请核实是否满足 AEC-Q200 等特殊可靠性认证)

四、设计与布局建议

  • DC 偏置与温度裕量:因 X5R 在直流偏置下容值下降,设计时保留裕量,必要时选择更大额定容值或并联组合以满足稳态需求。
  • PCB 焊盘与铺铜:遵循制造商的推荐焊盘尺寸与过孔策略,保证焊膏量均匀,减少 tombstoning 风险。焊盘对称、热量分布均衡有助于良好焊接。
  • 贴片工艺:适用于常规回流焊工艺(参考 J-STD-020 峰值温度),控制加热/冷却速率以降低热应力。

五、装配与存储注意事项

  • 包装形式:常见卷带供贴片机自动贴装;具体卷盘尺寸与数量以厂家包装信息为准。
  • 潮湿敏感性:MLCC 可能受潮敏感,建议遵循厂家关于干燥与回流前处理的建议;长期暴露在高湿环境时应进行适当回烘或按 MSL 要求处理。
  • 焊接建议:推荐使用标准无铅回流曲线,峰值温度依具体工艺确定(一般不超过 260°C)。

六、可靠性与选型要点

  • 可靠性:风华为主流厂商,生产工艺成熟,适合大批量应用。对关键应用建议参考详细可靠性试验报告(如温度循环、热冲击、湿热、振动等)。
  • 选型建议:若电路对容值稳定性要求高或工作电压接近额定值时,建议:
    1. 在原理图阶段考虑直流偏置后的有效容值;
    2. 必要时选用更高额定电压或更大封装以降低偏置影响;
    3. 在样机阶段完成温度/电压下的实际测试。

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
