URB4805YMD-6WR3是YLPTEC(易川)推出的1通道非隔离降压型DC-DC电源模块,专为工业控制、通信设备、医疗仪器等领域的高压宽输入转低压稳定输出需求设计。其核心价值在于以紧凑封装实现高可靠性、宽电压适应、低纹波噪声的供电方案,可直接替代传统线性稳压或低效开关电源,降低系统设计复杂度与成本。
该模块的核心参数围绕“宽输入、稳输出、高可靠”设计,具体如下:
内置短路保护机制,输出端意外短路时可快速切断输出,故障排除后自动恢复,避免模块及负载损坏;同时采用低功耗电路设计,待机功耗低,适合长期待机或低负载运行的系统(如传感器节点、远程监控设备)。
支持最大2200μF容性负载,可直接驱动后级大电容(如滤波电容、储能电容),无需额外设计负载匹配电路;输入电压18V~75V的宽范围覆盖,兼容工业24V/48V系统及电压波动(如电网波动、电池放电过程中的电压下降),减少输入稳压环节。
输出纹波噪声≤50mVp-p,满足对供电噪声敏感的电子元件(如高精度传感器、通信模块)要求;-40℃~+85℃的宽温工作范围,可适应户外、车间等高低温环境,无需额外散热或保温设计。
采用DIP-6直插封装,尺寸为25.4mm(长)×25.4mm(宽)×11mm(高),体积紧凑,可直接焊接于PCB板,安装方便;封装结构坚固,抗振动、抗冲击能力强,适合工业设备的振动环境。
URB4805YMD-6WR3的参数特性使其广泛适用于以下场景:
URB4805YMD-6WR3以高性价比、宽输入范围、高可靠性的特点,成为工业与通信领域高压转低压供电的优选方案。其紧凑封装、短路保护、低纹波等特性,可简化系统设计,提升设备稳定性,适合对供电要求严格的各类电子系统。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
