三星CL05B104KA54PNC是一款针对低压电路优化的贴片多层陶瓷电容(MLCC),依托三星成熟的陶瓷材料研发与叠层工艺,兼具小型化、宽温稳定性、高可靠性三大核心优势,广泛适用于消费电子、工业控制等领域的滤波、耦合场景。
该型号遵循三星MLCC命名逻辑,各代码含义清晰:
产品品牌为三星(SAMSUNG),封装规格为0402(英制代码,公制对应1005),是当前便携式设备的主流小型封装之一。
容值与精度
标称容值100nF,精度±10%,覆盖大多数通用电路的滤波、耦合需求(如电源纹波抑制、音频信号传递无需极高精度),避免容值波动导致电路性能不稳定。
额定电压
直流额定电压25V,适配3.3V、5V等低压系统(留有≥5倍电压裕量),可有效降低过压损坏风险,同时匹配便携式设备的低功耗设计要求。
温度系数(X7R)
采用X7R陶瓷介质,温度特性稳定:
0402封装的三星官方典型尺寸:
该封装体积小巧,可显著节省PCB空间(比0603封装体积减少约60%),适合智能手机、智能手环等高密度布局设备;同时支持自动化贴装,生产效率高,降低人工成本。
宽温稳定性
X7R介质使产品在-55℃至+125℃范围内保持容值稳定,避免因环境温度变化导致滤波、耦合效果下降,提升设备在极端环境下的可靠性(如户外安防摄像头、车载低压模块)。
低损耗特性
三星多层陶瓷叠层工艺优化了电极与介质的接触,等效串联电阻(ESR)≤10mΩ(1kHz时)、等效串联电感(ESL)≤0.5nH,适合高频电路(如射频耦合、电源纹波抑制),减少信号损耗与能量消耗。
环保与可靠性
符合RoHS 2.0、REACH等全球环保法规,无铅无卤;采用抗老化陶瓷材料,长期工作后容值衰减率≤5%(1000小时高温负载测试),可满足5年以上设备生命周期需求。
贴装兼容性
封装尺寸符合IPC J-STD-001标准,适配西门子、富士等主流贴片机,贴装良率≥99.5%,降低生产中的不良率。
消费电子
智能手机、平板电脑的电池供电电路滤波、音频信号耦合、射频前端匹配;智能手表的传感器模块稳压。
工业控制
小型PLC(可编程逻辑控制器)的I/O接口滤波、传感器(温度/压力)模块的EMI抑制、电机驱动电路的纹波过滤。
通信设备
路由器、交换机的以太网接口滤波、Wi-Fi模块的射频耦合、基站小型化单元的电源稳压。
车载低压电路
车载氛围灯、座椅调节控制器、USB充电模块的电源滤波(适配-40℃至+85℃车载环境)。
电压裕量
实际工作电压需低于25V DC,建议留有20%以上裕量(如最大工作电压≤20V),避免过压导致介质击穿。
温度控制
工作环境温度需控制在-55℃至+125℃之间,超出范围会导致容值漂移超过±15%,影响电路性能。
贴装工艺
存储条件
未开封产品存储于温度-40℃至+40℃、湿度≤60%的环境,避免阳光直射与腐蚀性气体;开封后建议12个月内使用完毕,防止电极氧化。
该产品凭借三星的工艺优势与稳定性能,成为通用低压电路的高性价比选择,可满足多数小型化电子设备的设计需求。
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.
