URB2412YMD-20WR3 产品概述

一、产品简介

URB2412YMD-20WR3 是 YLPTEC(易川) 推出的单路隔离型 DC-DC 模块,额定输出功率 20W,输入电压范围宽 (9V–36V),固定输出 12V,最大输出电流 1.666A。模块体积小巧(封装 DIP,尺寸 25.4 × 25.4 × 11.8 mm),适用于对体积、效率与隔离有要求的工业和通信应用场景。

二、主要技术参数

  • 通道数:1
  • 输入电压:9V ~ 36V
  • 输出电压:12V
  • 输出电流(最大):1.666A
  • 输出功率:20W
  • 转换效率:89%(典型)
  • 隔离电压:1.5 kVrms
  • 最大容性负载:1600 µF
  • 开关频率:250 kHz
  • 纹波噪声:50 mVp-p(典型)
  • 工作温度:-40℃ ~ +85℃
  • 特性:短路保护、低功耗

三、性能亮点与应用意义

  • 高效率(≈89%)在满载时典型损耗约为 2.5W(P_loss ≈ P_out*(1/η - 1)),有利于减小散热需求。
  • 宽输入范围适配 9–36V 工业/车载电源轨,输入电流随 Vin 变化:例如 Vin=9V 时输入电流约 2.5A,Vin=24V 时约 0.94A,Vin=36V 时约 0.62A(按满载与标称效率估算)。
  • 1.5 kVrms 隔离适用于信号隔离与地回路隔离,常见于工业控制、测量仪器与通讯设备的电气隔离要求。
  • 支持较大容性负载(1600 µF),适合驱动带大容性输入的后端电路(显示、采样前端等),但对冲击电流需做好输入限流与软启动管理。

四、热设计与可靠性建议

  • 满载时模块自身发热不可忽视(典型损耗约 2.5W),在高环境温度下建议改善散热:增加空气流通、散热铜箔或轻微导热至底板。
  • 在 50℃ 以上环境或密封箱体内长期工作时建议进行适当降额,以延长寿命并保证可靠性(具体降额曲线请参照详细技术手册)。
  • 建议在模块输入侧与输出侧分别配合低 ESR 电容以稳定工作并抑制瞬态。

五、EMI 与滤波建议

  • 250 kHz 开关频率为中频段,若系统对传导/辐射 EMI 要求严格,建议在输入侧加入共模/差模滤波(电感 + X/Y 或低 ESR 滤波电容),输出侧可并联 L-C 滤波降低输出纹波与噪声。
  • 对于超敏感模拟前端,推荐在输出端采用后级线性稳压或低噪放大器做二次滤波。

六、适用场景

  • 工业自动化控制与 PLC 信号隔离
  • 通信设备与基站辅电隔离
  • 仪器仪表、测试测量设备供电
  • 车载及轨道交通辅助电源(视系统认证要求)
  • 分布式供电、传感器节点和远端现场设备

七、选型与注意事项

  • 型号:URB2412YMD-20WR3,品牌:YLPTEC(易川)。
  • 确认系统所需隔离等级、输入瞬态耐受能力与短路保护行为(模块具备短路保护,具体为自动恢复还是折返式请参照完整规格书)。
  • 核对机械图与引脚定义,确保 PCB 布局留出足够散热面积并做好输入/输出旁路电容布局。
  • 如需并联冗余或并联输出增大功率,请与厂商确认并联可行性与均流方案。

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
