CS0J471M-CRE77 是 ROQANG(容强)推出的一款小型贴片铝电解电容,电容值为 470 µF,额定电压 6.3 V,容差 ±20%。该器件采用 SMD 封装,电容体直径 D=6.3 mm、长度 L=7.7 mm,适用于空间受限的电源旁路、滤波与去耦场合。设计强调高体积电容密度与可靠性,适配移动设备、通信与工业电子等多种应用。
纹波电流指标给出的是在 120 Hz 条件下的允许交流电流能力;在实际使用中,纹波频率、环境温度与 PCB 散热条件会影响电容发热与寿命,频率越高通常需关注电容的等效串联电阻(ESR)及其在高频下的表现。
CS0J471M-CRE77 为贴片型铝电解电容,标准化圆柱体 SMD 外形,直径 6.3 mm、长度 7.7 mm,便于自动贴装与回流焊工艺。封装小巧,适合对体积有严格限制的应用。设计 PCB 封装时应参考厂商推荐的焊盘尺寸与焊膏模板布局,以保证焊接可靠性与热分布均匀。
该系列电容在额定高温条件下经过寿命验证,适用于需要高温工作的场景。为延长使用寿命,建议在实际设计中采用温度与电压降额(例如降低实际工作电压、改善散热),行业常用经验是降低工作温度可显著延长电容寿命(每降低约 10 ℃ 寿命呈显著增长)。

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.
