GRM155R71H563KE14D 产品概述
一、概述
GRM155R71H563KE14D 是村田（Murata）出品的一款0402（公制1005）封装多层陶瓷电容器，额定参数为 56 nF（0.056 µF）、精度 ±10%、额定电压 50 V，介质类型为 X7R。该类型属于类 II 陶瓷，兼顾体积小、容量适中与成本效益，适用于各种消费类与工业电子产品中的旁路、耦合和滤波等应用。
二、关键参数
- 容值：56 nF（0.056 µF）
- 精度：±10%（K）
- 额定电压：50 V
- 介质：X7R（温度范围典型为 −55℃ 至 +125℃）
- 封装：0402（公制 1005）
- 品牌：Murata（村田）
三、材料与温度特性
X7R 为常用的类 II 压电陶瓷材料，具有在 −55℃ 至 +125℃ 范围内容值变化可控的特点（典型规范为温度引起的容值变化在一定范围内）。与 C0G/NP0 等一类介质相比，X7R 在体积同等情况下能提供更大的电容，但会出现温度依赖、直流偏置和长期老化等特性，需要在高精度电路中谨慎选用。
四、性能与注意事项
- 直流偏置效应：X7R 在施加直流电压时会产生显著的容值下降，尤其在小尺寸、高电压下更明显；设计时建议参考村田提供的直流偏置特性曲线并留有裕量。
- 频率特性：0402 尺寸带来较低的 ESL，可满足高频去耦需求，但在高频时介质损耗高于 NP0 型。
- 机械可靠性：0402 封装尺寸小，易受PCB弯曲或机械冲击造成裂纹；贴装与回流工艺需严格控制，避免应力集中。
- 环境合规：一般为无铅、RoHS 合规产品（具体证书请以厂商资料为准）。
五、封装与工艺建议
- 封装：标准 0402，适合高速贴片自动化装配。
- 回流焊：采用标准无铅回流温度曲线，遵循村田与焊膏供应商的推荐参数。
- 处理：避免在焊接后对板子施加较大弯曲力；储存与清洗按厂方说明进行，防止清洗工艺损害电容。
六、典型应用场景
- 电源去耦、旁路（CPU、模拟前端、射频模块附近）
- 高频滤波与噪声抑制
- 信号耦合/去耦与旁路网络（对容值精度要求不是极高的场合）
不适用于温度、频率或时间基准要求极高的精密振荡或计时电路。
七、选型建议与替代方案
- 若需更低温漂与更稳定容值，建议选用 C0G/NP0 系列（但容量可能需增大封装）。
- 若直流偏置影响不可接受，可考虑更大封装（0603/0805）或更适合高压稳定性的介质。
- 在高可靠或汽车级应用时，请确认是否需要 AEC‑Q200 认证型号或直接选用厂商标注的汽车等级产品。
八、进一步资料与采购
请在设计前参阅村田官方数据手册，获取完整的直流偏置曲线、温度特性、尺寸图和回流焊规程。采购时以官方料号 GRM155R71H563KE14D 为准，并向分销商确认包装卷轴（卷带）与最小起订量等信息。

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.
