VT1H2R2M0405 产品概述

一、产品简介

VT1H2R2M0405 为 ROQANG(容强)推出的一款贴片型铝电解电容,额定电容为 2.2 µF,公差 ±20%,额定电压 50 V。电容体尺寸紧凑,直径 4.0 mm,长度 5.4 mm(SMD,4×5.4 mm),适合空间受限的高密度 SMT 布局。该器件在 105℃ 下寿命为 2000 小时,工作温度范围为 -40℃ 至 +105℃,在低频环境下的纹波电流为 12 mA(120 Hz)。

二、主要规格一览

  • 品牌:ROQANG(容强)
  • 型号:VT1H2R2M0405
  • 容值:2.2 µF
  • 公差:±20%
  • 额定电压:50 V
  • 纹波电流:12 mA @ 120 Hz
  • 封装:SMD(贴片),电容体 Φ4.0 mm × L5.4 mm
  • 工作温度:-40℃ ~ +105℃
  • 额定寿命:2000 hrs @ 105℃

三、特性与优势

  • 体积小、容量适中:4×5.4 mm 的紧凑封装在高密度贴片板上更易布局,适合对体积有严格限制的电源滤波与旁路场合。
  • 中高电压能力:50 V 额定电压满足较高电压轨的去耦与滤波需求,比一般低压电解电容适用范围更广。
  • 高温寿命说明:2000 小时 @ 105℃ 的寿命等级,适合要求一定热稳定性的工业与消费类产品(需根据实际环境合理选型)。
  • 适用于低频纹波场合:标称 120 Hz 纹波电流 12 mA,适合市电整流后的滤波或低频电源纹波抑制。

四、典型应用场景

  • 开关电源一次侧滤波与整流滤波(非高纹波密度场合)
  • 模拟电路电源去耦、基准电压滤波
  • 工业控制、仪器仪表中对 50 V 轨或较高电压轨的旁路
  • 通信、消费类电路板中体积受限的滤波和耦合

五、安装与使用建议

  • 焊接工艺:作为 SMD 元件,应遵循 ROQANG 的焊接曲线与回流建议,避免超出推荐温度/时间对封装与内部电解质的损伤。
  • 极性注意:铝电解电容有极性,贴片时须严格区分正负极并保证丝印/标记正确,以免造成失效或短路。
  • 电压降额:为延长寿命,建议在高温或长期使用环境下对额定电压进行适度降额(一般工程实践中常采用 60%~80% 的降额范围,根据系统要求调整)。
  • 预留机械应力缓冲:尽量减少焊盘过大或过小导致的热膨胀/机械应力,合理设计焊盘和周边走线。

六、可靠性与储存

  • 寿命说明:2000 hrs@105℃ 为加速应力试验下的寿命标称值。实际使用寿命将随温度、电压和纹波等工作条件变化,常用经验为温度每下降 10℃ 寿命近似成倍增加。
  • 储存条件:建议在干燥、常温(5℃~35℃)及低湿环境下存放,避免长时间暴露于高温高湿或强腐蚀性气体环境,以防端子氧化和电解质性能退化。

七、注意事项

  • 评估纹波能力:本型号纹波电流标称较低,不适合承受高频大幅纹波或高纹波密度的电源节点,应在选型时与实际纹波需求对比。
  • 环境适配:若产品需长期在高温(接近或超过 105℃)或高纹波场景工作,应考虑使用更高寿命或更高纹波能力的电容器。
  • 可靠性验证:在关键应用中,建议进行样板测试与寿命验证(含温度循环、振动、焊接兼容性等)。

结论:VT1H2R2M0405 是一款针对中高电压轨、体积受限场合设计的贴片铝电解电容,适合一般去耦与滤波需求。选型时需综合考虑工作温度、纹波电流和寿命要求,合理降额并遵循厂家的焊接与储存规范以保证长期可靠性。若需更高纹波能力或更长寿命,请提供应用环境的具体参数以便推荐更合适的替代型号。

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.
