UV2G4R7M0810 贴片电解电容产品概述

UV2G4R7M0810是HONOR品牌针对高压电路小型化需求推出的贴片电解电容,聚焦400V高压场景下的滤波、耦合及去耦功能,以紧凑封装和稳定性能适配工业控制、电源设备等领域的实际应用。

一、产品基本属性

该型号属于铝电解电容范畴,采用贴片(SMD)封装形式,专为表面贴装工艺设计,无需插件焊接即可实现PCB集成。品牌为HONOR(荣誉),型号命名逻辑清晰:UV2G对应高压系列,4R7代表容值4.7μF,0810明确电容体尺寸为直径8mm×长度10.2mm,便于工程人员快速选型。

二、核心性能参数解析

2.1 电性能关键指标

  • 容值与精度:额定容值4.7μF,精度±20%,符合铝电解电容的常规精度等级,满足大多数工业级电路对容值偏差的容忍需求,无需额外高精度补偿;
  • 额定电压:400V DC(直流),是核心高压指标,可稳定工作在高压电路直流侧,避免过压击穿风险;
  • 工作寿命与温度:温度范围覆盖**-45℃~+105℃,宽温特性适配户外设备、温差较大的工业环境;工作寿命为3000hrs@105℃**,意味着在高温(如电源内部持续发热环境)下仍能保持稳定性能,满足长期运行需求。

2.2 物理尺寸特点

电容体直径8mm、长度10.2mm,属于小型化贴片电解电容,相比传统插件电解大幅缩小占用空间,适配高密度PCB布局,适合便携式高压模块、小型电源等对尺寸敏感的产品。

三、典型应用场景

UV2G4R7M0810的高压特性与紧凑封装,使其在以下场景中具有显著优势:

  1. 开关电源高压侧:AC-DC转换电路的高压滤波环节,滤除整流后的直流纹波,提升输出电压稳定性;
  2. LED驱动电源:高压线性驱动或开关驱动的输出滤波,抑制电压波动,保障LED灯珠寿命;
  3. 工业控制板:PLC、变频器等设备的高压信号耦合/去耦,隔离高低压信号,减少电磁干扰;
  4. 小家电高压电路:咖啡机、电压力锅等产品的控制板高压部分,适配小体积设计需求。

四、可靠性与环境适应性

  • 宽温稳定性:-45℃至+105℃的温度范围覆盖大部分工业设备工作环境(如户外控制柜、高温车间),低温下容值变化率符合行业标准,高温下无明显漏液、鼓包风险;
  • 回流焊兼容性:支持常规贴片回流焊工艺(峰值温度≤260℃,持续时间≤30s),避免焊接过程中损坏电容体;
  • 极性防护:电容体表面带有负极标识(如白色线条),明确提醒工程师焊接时注意正负极方向,防止反向电压导致电容失效。

五、选型与安装注意事项

  1. 选型匹配:需确认电路工作电压不超过400V DC,容值需求在4.7μF±20%范围内;若需更高精度,需选择±10%或±5%等级的电容;
  2. PCB布局:电容应靠近高压电路的滤波节点,减少布线长度以降低干扰;同时预留足够空间避免与周边元件碰撞;
  3. 焊接工艺:禁止手工焊接时烙铁温度过高(建议≤350℃,焊接时间≤5s),防止电容体受热损坏;回流焊后需检查极性是否正确,有无虚焊、假焊。

总结:UV2G4R7M0810贴片电解电容以高压、小体积、宽温稳定为核心优势,适配多种高压电路场景,是工业控制、电源设备等领域小型化设计的可靠选择。

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
