CSA0805X7R473K500KT 是 HRE(芯声)品牌的一款贴片多层陶瓷电容(MLCC)。器件采用 0805 封装,容值 47nF,公差 ±10%,额定电压 50V,温度特性为 X7R。该型号在体积、容量与可靠性之间取得平衡,适合通用去耦、旁路与滤波场合。
X7R 介质在宽温区间内保持较稳定的电容特性,适用于中低精度电路。0805 尺寸兼顾贴装可靠性与 PCB 布局密度,焊接工艺成熟。50V 额定电压使其能用于多数模拟与数字电源线路,47nF 的容量常见于去耦、旁路、RC 时间常数及耦合电路。器件具有良好的机械强度与可重复回流焊适应性。
选型时应关注电压依赖性与温度特性:X7R 在高偏压下会有一定容值下降(DC bias effect),若电路对容量敏感可考虑提高额定电压或换用介质差异更小的型号;焊接需遵循厂商回流曲线,避免温度冲击造成陶瓷裂纹;布局上去耦电容应尽量靠近电源引脚并缩短回流路径,以降低寄生电感。存储与使用时注意防潮、防机械应力。
HRE(芯声)提供 RoHS 合规产品,并可依据需求提供出货溯源与可靠性测试报告(如温湿热、热冲击及振动测试)。0805 封装适合自动贴装与大批量生产,供应渠道稳定,适用于样机验证到量产导入的各个阶段。
如需进一步的电气特性曲线(温度/频率依赖、DC bias 曲线)、封装图或回流焊工艺建议,可提供具体用途以便给出更精确的建议。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
