RT1A221M0605贴片铝电解电容产品概述

一、产品基本定位与核心参数

RT1A221M0605是容强(ROQANG)品牌针对小型化电子设备设计的贴片铝电解电容,属于低压小容值贴片系列,核心参数明确支撑基础滤波、耦合等应用需求。其型号编码对应特性清晰:「RT」代表铝电解电容系列,「1A」对应额定电压10V,「221」表示容值220μF(22×10¹),「0605」匹配封装尺寸(直径6.3mm×长度5.4mm)。核心参数包括:额定容值220μF(精度±20%)、额定电压10V、120Hz下纹波电流90mA、工作温度-40℃~+105℃、寿命2000hrs@125℃,是一款兼顾小体积与基础性能的实用型电容。

二、关键性能指标详解

1. 容值与精度

额定容值220μF,±20%的精度符合铝电解电容常规工业级标准,无需额外高精度补偿,可满足大部分电路对电容容量的基本滤波、耦合需求,降低设计成本与选型复杂度。

2. 电压与纹波耐受

  • 额定电压10V:适配低压直流电源系统(如5V/9V输出的小型电源、LED驱动电源);
  • 120Hz下90mA纹波电流:对应电容在工频纹波下的损耗控制,有效抑制电源输出的低频干扰,提升电路稳定性(适合家用/便携设备的电源滤波场景)。

3. 温度适应性

工作温度覆盖-40℃~+105℃,满足消费电子+小型工业场景的环境变化:低温下电容性能衰减可控(避免冬季户外设备失效),高温下仍能保持稳定工作(适配车载电子、高温厨房设备等)。

三、封装与物理特性

该型号采用SMD贴片封装,尺寸为D6.3mm×L5.4mm(电容体直径×长度),属于小型化贴片铝电解电容范畴:

  • 节省PCB空间:适配智能穿戴、小型家电等高密度电路设计;
  • 适配自动化生产:支持SMT贴装工艺,提升生产效率(避免插件电容的引脚占用与人工成本);
  • 贴装注意事项:需匹配PCB焊盘尺寸(常规贴片焊盘设计即可),确保焊接可靠性。

四、可靠性与寿命表现

核心寿命指标为2000hrs@125℃,是衡量电解电容长期可靠性的关键:

  • 高温稳定性:125℃环境下连续工作2000小时后,容值衰减、漏电流仍符合初始设计要求;
  • 常温寿命延伸:铝电解电容寿命随温度降低呈指数级提升,常温(25℃)下寿命可延长至数倍(满足一般设备5-10年使用周期);
  • 宽温可靠性:-40℃~+105℃范围进一步提升极端环境下的稳定性,适合户外传感器、车载辅助电路等场景。

五、典型应用场景

结合参数与封装特性,RT1A221M0605适用于以下场景:

  1. 低压电源滤波:移动电源、小型充电器、LED驱动电源的输出滤波;
  2. 信号耦合:蓝牙音箱、耳机等音频设备的信号耦合(隔离直流+传递音频);
  3. 小型工业模块:传感器节点、小型PLC的辅助电源滤波(适应工业温度变化);
  4. 消费电子便携设备:智能手环、智能手表的辅助电路(小体积适配内部空间)。

六、品牌与产品优势

容强(ROQANG)作为国内专注铝电解电容的品牌,RT1A221M0605具备以下优势:

  • 性价比突出:平衡小体积与纹波电流指标,避免小电容常见的纹波耐受不足问题;
  • 生产适配性强:SMD封装匹配主流SMT生产线,降低客户生产改造成本;
  • 服务支持:提供常规质保,支持批量选型与定制需求,适合中小批量设备制造商。

该型号通过参数优化与封装设计,成为小型化电子设备中低压滤波、耦合的实用选择,可覆盖多场景的基础电容需求。

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
