URB4812YMD-6WR3 产品概述

一、产品简介

URB4812YMD-6WR3 是 YLPTEC(易川)推出的一款高性能双输出隔离式DC-DC稳压模块。该模块采用4:1超宽输入设计,适用于18V~75V的工作电压范围,单体输出功率可达6W,具有高效率、宽温区和强隔离性能,适合在恶劣工业环境和要求严格的系统中长期稳定工作。

二、主要技术参数

  • 输入电压:18V ~ 75V(4:1超宽输入)
  • 输出通道:2路,输出电压:12V,输出电流(最大):500mA
  • 输出功率:6W
  • 转换效率:高达91%(典型值约87%)
  • 隔离电压:1500VDC(标称1.5kVrms)
  • 最大容性负载:680µF
  • 开关频率:250kHz
  • 纹波噪声:约50mVp-p
  • 工作温度:-40℃ ~ +85℃
  • 外形尺寸:25.4mm × 25.4mm × 11mm,DIP封装

三、功能与保护

URB4812YMD-6WR3 提供完善的保护与可靠性设计,包含:

  • 输入欠压保护,防止输入瞬变导致模块异常工作;
  • 输出过压保护,避免负载或系统异常时损伤下游电路;
  • 过流保护与短路保护,确保在短路或过载情况下安全限流或自恢复;
    这些保护机制提升了系统可靠性,便于在多变的供电与负载条件下使用。

四、电气与机械特性

该模块为稳压型设计,输出稳定、噪声低(典型纹波50mVp-p),允许较大的输出电容(最大680µF)以满足不同滤波需求。250kHz的开关频率使得变压器和电感体积可控,配合25.4×25.4×11mm的小巧封装,有利于空间受限的场合布局。裸机设计满足CISPR32/EN55032 Class A电磁兼容要求,便于工程时的整机EMC优化。

五、应用领域与使用建议

适用领域广泛:医疗设备、工业控制、电力系统、仪器仪表、通信设施、轨道交通等需要高隔离、宽输入与高可靠性的场合。使用建议包括:

  • 布局时注意散热通道与靠近热源距离,尽量在PCB上保留热扩散铜箔;
  • 输入端加装合适的滤波与保护器件以应对尖峰脉冲;
  • 输出端配合低ESR电容以优化启动与纹波表现;
  • 在涉及安全认证或更高EMC等级的应用中,结合整机滤波与屏蔽设计共同达标。

URB4812YMD-6WR3 以小体积、高效率和丰富的保护特性,为对隔离、安全与稳定性有严格要求的系统提供可靠电源解决方案。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
