CL21B475KAB6PNE是三星电子推出的车规级多层陶瓷电容(MLCC),专为汽车电子领域的宽温、高可靠性场景设计,兼顾小型化与电气性能稳定性,是车载电子系统中滤波、耦合等功能的核心被动元件之一。
该型号属于三星车规MLCC产品线,型号编码对应明确的技术特征:
其核心定位是汽车电子低电压场景的通用被动元件,覆盖车载信息娱乐、传感器、车身控制等多类模块,替代普通民用电容以满足汽车环境的可靠性要求。
标称容值为4.7μF,精度±10%(代码K),既避免容值偏差过大影响信号完整性,又具备批量生产一致性。容值采用EIA标准标识(475),便于工程师快速识别,适配滤波、耦合等基础功能需求。
额定工作电压为25V DC,适配车载12V/24V电源系统的辅助电路(如传感器供电、小信号处理),电压裕量充足(实际工作电压远低于额定值),可有效降低击穿风险,提升长期可靠性。
采用X7R温度特性,是车规MLCC中最常用的宽温方案:
采用0805英制封装(对应公制2012,即2.0mm×1.2mm),尺寸紧凑,适配车载电子系统的高密度PCB设计(如摄像头模块、胎压监测传感器等小型化组件),有效节省电路板空间。
封装采用陶瓷-金属复合结构,电极采用镍基材料(抗老化、低电阻),焊接兼容性良好,支持回流焊、波峰焊等主流SMT工艺,无铅环保(符合RoHS标准),满足汽车电子的量产工艺要求。
CL21B475KAB6PNE通过AEC-Q200汽车电子可靠性认证,针对汽车环境的特殊要求做了以下优化:
该型号广泛应用于车载电子系统的多个核心模块:
三星电子作为全球领先的被动元件供应商,其车规MLCC具备以下优势:
综上,CL21B475KAB6PNE是一款专为汽车电子场景优化的高可靠性MLCC,兼顾小型化、宽温稳定性与电气性能,是车载电子系统中替代普通民用电容的理想选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
