ROQANG RT1A470M0505 贴片铝电解电容产品概述

一、产品基本定位

RT1A470M0505是容强(ROQANG)针对低压小型化电路推出的贴片型铝电解电容,核心围绕“小尺寸、宽温稳定、高性价比”设计,适配SMT自动化贴装生产线,是消费电子、小型电源、工业低功耗电路等领域的常用滤波/耦合元件。

二、核心性能参数解析

2.1 容值与精度

标称容值为47μF,精度±20%,既满足大多数低压电路对滤波容量的基本需求,又通过合理精度控制平衡了成本与性能——实际应用中,容值偏差在±20%内不会影响电源滤波、信号耦合等核心功能的稳定性。

2.2 额定电压与纹波能力

  • 额定电压10V:适配5V、9V等常见低压直流电路(如USB供电、MCU辅助电源),避免过压击穿风险,同时预留一定安全裕量;
  • 纹波电流31mA@120Hz:针对市电整流后120Hz的纹波频率优化,可有效抑制电源输出纹波(如开关电源的高频纹波+线性纹波叠加),保障后级敏感电路(如传感器、蓝牙模块)的供电质量。

2.3 温度与寿命特性

  • 工作温度范围:-40℃~+105℃:覆盖工业级宽温需求(如户外设备、车载辅助电路),低温环境下容值衰减率≤10%(-40℃下24h),高温下仍能保持容值稳定;
  • 高温寿命:2000hrs@105℃:即105℃环境下连续工作约83天,容值仍维持在额定值的80%以上,满足长期稳定运行的可靠性要求(实际应用中若环境温度低于105℃,寿命会显著延长)。

三、封装与尺寸设计

采用SMD贴片封装,电容体尺寸为直径5mm×长度5.4mm(D5×L5.4mm),属于小型化贴片铝电解规格:

  • 适配常规PCB焊盘(如0805、1206焊盘布局,需确认具体设计),贴装效率高,适合批量生产;
  • 小尺寸设计可有效节省PCB空间,尤其适合便携式设备(如智能手环、TWS耳机)、小型电源模块(如5V/1A USB电源)等紧凑布局场景。

四、典型应用场景

  1. 小型直流电源模块:如手机充电器、USB-C PD电源的输出滤波,利用47μF容值抑制开关纹波,10V额定电压适配低压输出;
  2. 便携式消费电子:智能手表、蓝牙耳机的辅助电源滤波,小尺寸适配设备内部狭小空间,宽温特性适应人体佩戴的温度波动;
  3. 工业低功耗电路:PLC模块的辅助电源、传感器节点的供电滤波,-40℃~+105℃宽温满足工业环境的高低温变化(如车间、户外基站);
  4. 消费类家电配件:机顶盒、路由器的电源板滤波,高性价比与稳定性能适配量产需求,降低BOM成本。

五、品牌与可靠性保障

容强(ROQANG)作为国内铝电解电容主流厂商,RT1A470M0505经过常规可靠性测试(高温存储、温度循环、耐湿性测试),贴片封装的一致性良好(焊盘平整度、尺寸公差控制在±0.1mm内),可减少SMT生产中的不良率;同时,电解液配方优化降低了高温下的干涸速率,实际使用寿命比标称值更长(如60℃环境下寿命可达10000hrs以上)。

该产品凭借“小尺寸、宽温稳定、高性价比”的核心优势,已成为众多中小厂电子设计的常用选择,尤其适合对成本敏感、空间有限的低压电路场景。

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
