CL21B104KCFNNNE是三星电子(SAMSUNG) 推出的0805封装X7R系列通用型贴片多层陶瓷电容(MLCC),型号命名直接映射核心参数:
该型号属于工业级标准品,覆盖中低压电路的滤波、耦合与去耦场景,是量产电路的优选元件。
容值为100nF(10⁻⁷F),精度±10%(K档)——既无需C0G系列的超精密成本,又避免Y系列(如Y5V)容值随温度/电压剧烈变化的问题。实际应用中,±10%的偏差可通过“多电容并联”进一步优化,满足90%以上通用电路的匹配需求。
采用0805英制封装(公制2012),尺寸为2.0mm(长)×1.2mm(宽)×0.8mm(典型厚度),符合IPC-A-610标准:
CL21B104KCFNNNE的参数特性使其成为以下场景的核心元件:
注意:不适合超高频(>100MHz)电路(如射频振荡器)或超精密场景(如医疗传感器),此类场景建议选用C0G系列。
实际工作电压建议不超过80V DC(额定电压的80%),避免长期过压导致陶瓷介质老化、容值下降。例如,若电路工作电压为72V,100V电容已满足余量要求。
CL21B104KCFNNNE作为三星成熟型号,核心优势显著:
该型号已通过RoHS、REACH等环保认证,符合全球电子行业合规要求,是工业、通信、消费电子领域的高性价比选择。

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.
