16YXJ4700M16X25 产品概述

一、产品简介

16YXJ4700M16X25 是 rubycon(红宝石)生产的一款径向铝电解电容器(插件式),额定容量 4700µF,额定电压 16V,适用于各类电子设备的滤波和储能场合。电容体尺寸为直径 16mm × 长度 25mm,脚距 7.5mm,封装为 D16×L25mm,便于电路板插件和机械固定。

二、主要参数

  • 容值:4700µF(±20%)
  • 额定电压:16V
  • 纹波电流:2.344A @ 120Hz
  • 等效串联电阻(ESR):21 mΩ
  • 工作温度:-40℃ ~ +105℃
  • 工作寿命:10000 小时(+105℃)
  • 封装/引脚:径向插件,脚间距 7.5mm,D16×L25mm
  • 品牌:rubycon(红宝石)

三、性能特点与适用场景

  • 低 ESR(≈21mΩ)带来较小的损耗和发热,适合做电源输出滤波、整流桥后端滤波及开关电源输入侧的储能元件。
  • 2.344A 的纹波电流能力在 120Hz 下表现良好,能承受一般电源整流后的交流纹波;在高频开关场合可作为大电容平滑元件,配合低 ESR 的陶瓷/固态电容共同使用。
  • 额定 16V 适用于 12V 及以下电源轨(常见为 5V/12V/15V 系统的缓冲与滤波)。
  • 长寿命 10000 小时 @105℃ 表明器件为高温长期工作的工业级选择,适合工业电源、通信设备、LED 驱动及消费类电器的关键滤波位置。

四、选型与并联建议

  • 若系统纹波或瞬态电流超出单颗容量承受范围,可并联多只电容以降低等效 ESR 并提高总纹波能力;并联时应尽量选择相同型号以获得一致的阻抗特性。
  • 建议在高温或高压纹波工况下进行电压降额(derating),一般可将工作电压降至额定值的 60%~80% 以延长寿命。经验上每降低 10℃ 寿命可显著延长,但具体需参考厂商曲线。

五、安装、可靠性与注意事项

  • 插件式封装,焊接时应遵循厂商推荐的温度/时间曲线,避免长时间高温导致电解液劣化;波峰或选择性焊接时注意预热与快速冷却。
  • 极性电容,安装时务必确认正负极,反向电压会引起失效甚至爆裂。产品顶部一般设有安全泄压标记,请勿覆盖。
  • 长期储存应避免高温高湿环境,开封后尽量缩短使用前的存放时间。电容 ESR 与容量会随温度、使用时间和纹波应力变化,应在设计中留有裕量。

总结:16YXJ4700M16X25 以其大容量、低 ESR、较高纹波承载力及 105℃/10000h 的长寿命特性,是对空间有限但需稳健滤波与能量缓冲场合的实用选择。

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
