CL21A476MPYNNWE是三星电子(SAMSUNG)推出的一款X5R介质片式多层陶瓷电容(MLCC),专为低电压、高容值需求的表面贴装应用设计,具备尺寸紧凑、稳定性良好、适用场景广泛等特点,是消费电子、小型工业设备等领域的常用基础元器件。
该型号属于三星CL21系列MLCC产品,聚焦0805英制封装(对应公制尺寸2.0mm×1.25mm)的小尺寸高容值需求场景,主要解决低电压电路中的滤波、耦合、旁路等功能,平衡了容值密度与温度稳定性,适合对尺寸敏感但对容值变化要求适中的应用。
标称容值为47μF(即47微法,对应电容标识“476”——1μF=10⁶pF,47μF=47×10⁶pF=476pF),精度为**±20%**,属于工业级通用精度范围,满足大多数非高精度电路的需求,无需额外容值筛选即可批量应用。
额定电压为10VDC,适用于低电压供电的电子设备(如5V/3.3V系统的电源滤波);介质类型为X5R,是MLCC中兼顾容值密度与温度稳定性的主流介质之一。
X5R介质的温度适用范围为**-55℃至+85℃**,在该区间内电容容值变化≤±15%,远优于Y5V等低成本介质(Y5V容值变化可达±20%~+82%/-82%),能在环境温度波动较大的场景下保持稳定性能。
该产品采用0805英制表面贴装封装,典型物理参数如下:
封装符合RoHS 2.0环保标准(无铅、无镉、无汞),兼容主流SMT贴装设备,焊接可靠性高,可通过回流焊、波峰焊实现批量生产。
三星电子作为全球MLCC主要供应商,具备完善的生产与品控体系:
综上,CL21A476MPYNNWE凭借高容值密度、宽温稳定性与小尺寸优势,成为低电压电子设备滤波、耦合等功能的理想选择,适用于对成本与性能平衡要求较高的通用场景。

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.
