RVT1H331M1213是容强(ROQANG)品牌推出的通用型贴片铝电解电容,专为表面贴装(SMD)工艺设计,属于中高压、中等容量的滤波类器件,适配自动化生产流程,可满足工业控制、消费电子等多领域的电源滤波、耦合需求。
标称容值330μF,精度±20%,符合铝电解电容的工业级常规精度标准,无需额外校准即可覆盖大部分滤波场景的容量需求。
50V直流(DC),为长期连续工作的最大允许电压,选型时建议预留1.2~1.5倍电压余量(如电路工作电压40V需选50V及以上型号),避免过压损坏。
320mA@120Hz,表示120Hz交流纹波下的最大允许电流,直接影响滤波效果——过高纹波电流会导致电容发热,加速老化缩短寿命。
SMD贴片封装,无引脚设计,适配回流焊、波峰焊等自动化贴装工艺,可提升生产效率、降低人工焊接误差。
电容体直径12.5mm×长度13.5mm,属于中等体积贴片铝电解电容,PCB布局需预留周边1mm以上间隙(避免散热不良)。
铝电解电容为有极性器件,封装表面标注白色条纹/色环(负极),焊接时需严格匹配电路极性,反接会导致电容损坏甚至爆炸。
-40℃~+105℃,覆盖工业级宽温需求,可在低温(北方户外设备)、高温(密闭机箱)环境稳定工作。
2000hrs@105℃,表示105℃高温下连续工作2000小时后,容值变化仍在±20%以内;常温(25℃)下寿命可延长至数万小时,满足工业设备长期运行要求。
符合常规贴片元件标准,存储/使用时避免长期暴露在相对湿度>85%的环境中,以免影响铝箔氧化层稳定性。
该产品凭借稳定的电气性能、宽温适应性与贴片工艺优势,成为多领域电子设备的实用选择。

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.
