Rubycon(红宝石)作为日系铝电解电容领域的知名品牌,其50THV100M10X10.5型号是一款专为宽温环境、高频滤波场景设计的贴片铝电解电容,兼顾小体积、高可靠性与成本效益,广泛适配工业、汽车电子等对环境适应性要求较高的领域。
该型号的参数设计精准匹配中高压、宽温滤波需求,关键参数及意义如下:
标称容值100μF,精度**±20%**,满足绝大多数电源滤波、耦合电路的基本容值需求。±20%的精度在工业级应用中属于常规且可靠的范围,无需额外高精度补偿,适配批量生产时的参数一致性要求。
直流额定电压50V,为工作电压提供充足余量(建议实际工作电压不超过40V以延长寿命),可覆盖常见低压直流电源系统(如24V、36V工业电源、12V/24V车载系统),避免过压击穿风险。
贴片式(SMD)封装,电容体直径10mm、长度10.5mm,属于紧凑尺寸设计:
结合参数特性,该型号主要适配以下场景:
适用于PLC、变频器、伺服驱动器等工业设备的开关电源输出滤波:
适配车载中控、车灯控制器、电池管理系统(BMS)的辅助电源滤波:
基站RRU、路由器、交换机的直流电源滤波:
高端家电(变频空调、智能冰箱)的电源模块滤波:
对比同类贴片铝电解电容,该型号具备以下突出优势:
Rubycon THV系列针对高温场景优化,3000hrs@125℃的寿命比普通贴片电容长2-3倍,减少设备维护频率,降低全生命周期成本。
在100kHz高频下同时具备低ESR与合适的纹波电流能力,避免“低ESR但纹波电流不足”或“纹波电流高但ESR大发热严重”的问题,平衡滤波效果与损耗。
10x10.5mm尺寸下实现100μF/50V的容值电压,密度高于同规格普通贴片铝电解,适配小型化、高密度设备设计。
Rubycon生产工艺成熟,批量产品的容值、ESR、寿命等参数一致性好,降低终端设备的性能波动风险,提升产品合格率。
为保障设备可靠性,需注意以下要点:
实际工作电压建议不超过额定电压的80%(≤40V),避免长期过压导致电容电解液干涸,缩短寿命。
实际电路中的纹波电流(100kHz下)不超过350mA,若需更高纹波电流,可并联多个电容(并联后纹波电流能力累加)。
未使用的电容应储存在**25℃±5℃、湿度≤60%**的环境中,储存期不超过12个月;超出储存期需重新测试容值、ESR等关键参数,合格后方可使用。
该型号凭借宽温稳定性、高频滤波能力与小体积设计,成为工业、汽车电子等领域的高性价比选择,可有效提升终端设备的可靠性与紧凑性。

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.
