RVT1H331M1213 贴片铝电解电容产品概述

一、产品核心身份与定位

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。

二、关键电气性能参数

1. 容值与精度

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。

2. 额定电压

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。

3. 纹波电流能力

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。

4. 型号编码解析

  • “RVT1H”中“1H”对应50V额定电压;
  • “331”对应330μF(33×10¹);
  • “M1213”中“12”“13”分别对应电容体直径12.5mm、长度13.5mm,编码逻辑清晰便于选型。

三、物理与封装特性

1. 封装类型

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。

2. 尺寸规格

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)。

3. 极性标识

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。

四、环境适应性与可靠性

1. 工作温度范围

-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。

2. 工作寿命

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。

3. 耐湿性

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。

五、典型应用场景

  1. 电源滤波:开关电源、线性电源输出端滤波,抑制直流纹波提升电源纯度;
  2. 工业控制:PLC、变频器、伺服驱动器辅助电源滤波,适配工业宽温与可靠性要求;
  3. 消费电子:机顶盒、路由器、智能家居设备电源模块,满足中等容量滤波与贴片工艺需求;
  4. 车载电子:12V/24V低压车载电路(如辅助电源),宽温特性适应车载温度变化(需确认电压匹配)。

六、选型与使用注意事项

  1. 电压余量:额定电压需大于实际工作电压的1.2倍以上;
  2. 纹波控制:实际纹波电流需低于320mA@120Hz,过大则并联电容或换高纹波型号;
  3. 焊接规范:回流焊峰值温度220~230℃,时间不超10秒,避免高温损坏;
  4. 存储条件:未焊接电容存于030℃、40%60%湿度环境,存储期不超1年;
  5. 极性检查:焊接前确认电容负极与电路极性一致,严禁反接。

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。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
