RVT1E471M1010是ROQANG(容强)品牌推出的一款贴片型铝电解电容,针对中低容值、中低电压的滤波/耦合需求设计,兼具小型化封装与宽温适应性,可覆盖消费电子、工业控制、车载辅助电路等多场景的基础电源及信号处理单元,是紧凑电路布局中的实用选型。
电容标称容值为470μF,精度±20%——符合铝电解电容的常规精度等级,能满足多数电子设备对滤波、耦合的基本性能要求,无需高精度电路的场景可直接适配,无需额外匹配高精度电容。
额定直流电压为25V,明确了电容可长期稳定工作的最高直流电压值(需注意:交流纹波叠加后峰值电压不得超过25V),适配12V、24V等常见低压电源系统,无需担心过压风险。
在120Hz(市电整流后典型纹波频率)下,最大耐受纹波电流为286mA——该参数直接反映电容的热耐受能力:若实际电路纹波电流接近此值,需注意PCB布局预留散热空间,避免电容过热老化。
宽温设计,工作温度区间为**-40℃~+105℃**,可适应从低温环境(如北方户外设备)到高温环境(如密闭机箱内)的温度变化,拓展了应用场景的多样性,无需额外增加温度补偿电路。
采用SMD(贴片式)封装,支持自动化贴装生产,适配PCB密集布局设计,适合批量生产场景,降低人工成本,同时避免插件式电容的引脚占用空间问题。
电容体直径10mm,长度10.2mm,属于小型化贴片电解电容——相比插件式电解,节省约30%的PCB空间,适合便携式设备(如手持终端)、紧凑型电路(如电源模块)的布局需求,尤其适用于空间受限的设计。
在105℃高温环境下,连续工作寿命为2000小时——根据电解电容寿命的阿伦尼乌斯定律,环境温度每降低10℃,寿命约延长1倍(如85℃时寿命约4000小时,65℃时约8000小时),实际应用中寿命远高于标称值,满足长期稳定工作需求。
由ROQANG(容强)品牌生产,该品牌专注铝电解电容研发制造多年,产品经过常规环境测试(如高低温循环、湿度测试、振动测试),可靠性符合民用及工业基础场景的使用要求,无需担心批量失效问题。
结合产品参数,RVT1E471M1010的核心应用场景包括:
综上,RVT1E471M1010以其平衡的性能参数、小型化封装及宽温适应性,成为中低压电路滤波/耦合场景的高性价比选型,可满足多数民用及工业基础设备的使用需求。

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.
