08055C473JAT2A — 0805 47nF ±5% 50V X7R 多层陶瓷电容器（AVX）产品概述
一 产品简介
08055C473JAT2A 是 AVX 出品的一款通用型贴片多层陶瓷电容（MLCC），标称电容为0.047µF（47nF），容差±5%，额定电压50V，温度特性为 X7R。器件采用0805（2012 公制）封装，尺寸 2.01mm × 1.25mm，最大厚度 0.94mm，适用于各类电子设备中的去耦、滤波与耦合应用。
二 主要技术参数
- 电容：0.047µF（47nF）
- 容差：±5%（J）
- 额定电压：50V DC
- 温度系数：X7R（-55°C 至 +125°C，典型容量变化范围在 ±15%）
- 工作温度范围：-55°C ~ +125°C
- 封装：0805（2012 公制）SMD
- 尺寸：0.079" × 0.049"（2.01mm × 1.25mm），厚度 ≤ 0.037"（0.94mm）
- 安装类型：表面贴装，多层陶瓷结构
三 电气与性能特点
- X7R 陶瓷介质在宽温度范围内保持较稳定的电容值，适合一般去耦与旁路用途；需要注意 X7R 为介电常数较高的通用型材料，其电容会随温度与直流偏压（DC bias）产生一定程度的变化，实际电路设计时应预留裕量并在目标工作电压下验证电容有效值。
- ±5% 容差适合对容值有中等精度要求的滤波与时间常数电路。
- 50V 额定电压提供对中低压供电系统的良好耐压余量。
四 应用场景
- 电源去耦与旁路：靠近IC电源引脚用于抑制高频噪声。
- 模拟滤波与时间常数电路：耦合、滤波、RC 延时等。
- 通用消费电子、通信、工业控制和测量设备中的小型化电容需求。
- 适用于高密度贴装的 PCB 设计，兼顾体积与性能。
五 PCB 布局与装配建议
- 将电容尽量放置在被滤波器件的电源引脚附近，连接走线短且宽，以降低寄生电感与阻抗。
- 采用适合0805 封装的焊盘尺寸并保证足够的焊锡覆盖以利于可靠焊接。
- 避免在焊接或机械应力集中的区域直接放置，陶瓷元件对弯折应力敏感，需注意基板材料与组装工艺。
- 兼容常规 SMT 回流焊工艺；生产时建议遵循元件厂商的回流曲线与储存、烘烤说明以防潮气导致裂纹或焊接缺陷。
六 选型与可靠性注意事项
- 若电路对温度稳定性或高精度容值要求更高，可考虑温度系数更好的薄膜/电解等其他类型电容或选择公差更小的器件。
- 在高直流偏置场合下，应测量工作电压下的实际电容量并据此调整设计。
- AVX 品牌在元器件可靠性与批次一致性方面具有良好口碑，适合量产与长期供应，但具体认证（如 AEC-Q200 等）请参考厂商资料以满足汽车或特定行业要求。
如需用于特定工况（高频、脉冲电流、大电流旁路或汽车级应用），建议提供详细电路参数以便进一步评估与推荐替代型号。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
