TAIYO YUDEN(太诱)作为全球多层陶瓷电容(MLCC)领域的核心供应商,其推出的MSASL105BB5475MFNB33型号贴片电容,以紧凑封装、稳定电气性能及可靠品质,成为消费电子、可穿戴设备等小型化场景的优选元件。以下从核心参数、特性及应用维度展开概述。
该型号属于通用型MLCC,聚焦对尺寸敏感的电子设备,以“小体积+稳定性能”为设计核心,适配高密度贴片组装工艺,满足量产环节的效率与一致性需求,是替代传统铝电解电容、优化电路体积的理想选择。
标称容值为4.7μF(对应电容代码“475”,即47×10⁵ pF),精度等级为±20%,属于商业级常规精度,可覆盖大多数不需要极高容值精度的场景(如电源滤波、低频信号耦合)。
直流额定电压为10V,需注意:实际工作中需遵循电压降额原则(建议最大工作电压不超过8V),避免过压导致电容击穿或性能衰减;若应用于交流电路,需根据频率计算有效电压并进一步降额(如1kHz下有效电压不超过7V)。
采用X5R温度系数,其定义为:工作温度范围-55℃+85℃,在此区间内容值变化率不超过±15%。该特性兼顾了成本与性能稳定性,适合一般环境温度下的设备(如室内电子设备、常温工业场景),优于X7R(-55℃+125℃)但更具性价比。
采用0402英寸封装(公制约1.0mm×0.5mm),是目前小型化电子设备中广泛使用的封装之一,高度约0.5mm(典型值),可适配高密度PCB布局,有效缩小整机体积(如智能手机主板可节省约30%的电容占用空间)。
封装结构符合JEDEC标准,支持回流焊工艺(推荐温度曲线匹配太诱官方规范:峰值温度245℃±5℃,回流时间≤30s),焊接后无开裂风险;同时具备一定的机械强度,可承受常规组装过程中的轻微应力(如PCB弯曲≤0.5mm)。
基于多层陶瓷叠层工艺,具有低等效串联电阻(ESR)(典型值≤10mΩ@1kHz)和低等效串联电感(ESL)(典型值≤0.5nH)特性,尤其适合高频电路中的滤波应用,可减少信号损耗与噪声干扰(如蓝牙模块的射频滤波)。
太诱作为老牌元器件厂商,该型号通过了RoHS、REACH等环保认证,且在长期可靠性测试中表现优异:
结合参数与特性,该型号主要适用于以下场景:
该型号凭借平衡的性能与成本,成为小型化电子设备中通用MLCC的可靠选择,太诱的稳定供应也为量产环节提供了保障,适合中小批量到大规模生产的需求。
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.
