  • 容值:220 μF
  • 公差:±20%
  • 额定电压:35 V
  • 纹波电流:195 mA @ 120 Hz
  • 尺寸(电容体):直径 8 mm × 长度 10.2 mm(D8 × L10.2 mm)
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 工作寿命:2000 小时 @ 105 ℃

二、产品特点与优势

  • 小体积高容量:D8×L10.2mm 的贴片封装在保持 220 μF 容量的同时,便于高密度 PCBA 布局,适合空间受限的电子设备。
  • 高温寿命保证:2000 小时 @ 105 ℃ 的寿命等级,适用于要求较高温度稳定性的电源和工业类应用。
  • 可靠的纹波处理能力:195 mA(120 Hz)纹波电流指标,满足中低功率电源滤波与去耦需求。
  • 宽温度范围:-40 ℃ 至 +105 ℃ 的工作温度覆盖汽车电子、工业控制等严苛工况(请根据实际认证情况确认是否用于汽车级应用)。
  • 贴片化生产兼容:SMD 封装适配自动贴装与回流焊流程,有利于批量制造与装配效率提升。

三、典型应用场景

  • 开关电源输出侧滤波与储能:用于DC-DC转换器、开关电源输出端,起滤波、平滑输出与瞬态供电作用。
  • 电源旁路与去耦:用于主板、通讯设备、工业控制模块的去耦与电压稳定。
  • 音频与模拟电路:在电源端为放大器、信号链提供低频能量储备与纹波抑制(注意电容极性与噪声要求)。
  • 工业与消费类电器:适用于对温升和可靠性有一定要求的设备,如监控设备、电源模块、家用电器控制板等。

四、选型与使用建议

  • 极性注意:铝电解电容为极性元件,使用时必须确保正负极接线正确,避免反向电压造成损伤或失效。
  • 电压降额:为延长寿命与提高可靠性,建议在实际应用中对额定电压进行适当降额(常见做法为使用额定电压的 70%~90%),尤其在高温或长时间运行工况下。
  • 温升管理:回路中的实际温度(尤其靠近发热器件处)会显著影响寿命,建议合理布局并留出散热路径。
  • 纹波与寿命关系:纹波电流会导致内部温升,长期接近或超过标称纹波电流会缩短寿命,应根据实际纹波测量值评估可靠性。

五、封装与焊接注意事项

  • 回流焊兼容性:作为SMD封装元件,VT1V221M0810适配常规回流焊流程。为保证焊接可靠性,请遵循厂商的回流温度规范与峰值温度限制(如有厂方推荐回流曲线,应优先采纳)。
  • 焊盘与机械应力:建议设计合理的焊盘尺寸和过孔布局,避免在回流及使用过程中对电容本体施加过大机械应力。对于振动或冲击环境,可考虑在焊接完成后使用点胶固定以提升机械可靠性。
  • 清洗与化学兼容性:回流焊后清洗时注意溶剂和工艺对铝电解电容外壳与密封性能的影响,遵循常规清洗兼容性原则。

六、品质与检测要点

  • 关键参数检验:验收时应检测容量(±20%)、漏电流、耐压、纹波电流性能及等效串联电阻(ESR)等关键电参。
  • 加速老化与高温测试:对关键产品批次建议进行高温老化与纹波耐受试验,验证在目标工况下的寿命表现与失效模式。
  • 储存与保管:未使用产品应存放在干燥、常温环境,避免长时间受潮或高温影响,以免影响焊接性与电性能。

七、型号说明(参考)

  • 型号 VT1V221M0810 中 “221” 通常表示 220 μF 容值,“M” 表示 ±20% 公差,“08” 可能对应电容体直径 8 mm,后缀“10” 对应长度 10.2 mm。具体型号编码规则请以厂方说明为准。

如需器件的详细电气等效参数(如 ESR、ESL、漏电流曲线、回流曲线及详细可靠性报告),建议联系 ROQANG(容强)获取完整数据手册与验证资料,以便在设计中完成最终选型和可靠性评估。

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
