URB4812S-10WR3 产品概述

一、产品简介

URB4812S-10WR3 是 YLPTEC(易川) 出品的一款隔离型直流-直流降压模块,额定输出功率 10W,专为 48V 直流母线到 12V 负载供电而设计。模块采用 SIP 小封装(22 × 9.5 × 12 mm),开关频率 300kHz,具备良好的效率与抗干扰性能,适合通信、电源分配、工业控制及分布式供电等场景。

二、主要指标

  • 输入电压:48V(额定)
  • 输出电压:12V
  • 输出功率:10W
  • 输出电流(最大):833mA
  • 转换效率:典型 86%
  • 最大容性负载:330µF
  • 纹波噪声:75mVpp(典型)
  • 隔离电压:1.5kVrms
  • 开关频率:300kHz
  • 工作温度范围:-40℃ 至 +85℃
  • 保护功能:欠压保护、过流保护、短路保护
  • 封装:SIP,尺寸 22 × 9.5 × 12 mm

三、主要特性与优势

  • 小型化封装,节省 PCB 面积,便于模块化电源设计与并联冗余布局。
  • 较高转换效率(≈86%),减小发热量,有利于长期稳定运行。
  • 完整的保护机制(欠压、过流、短路),提高系统可靠性与故障自复位能力。
  • 1.5kVrms 隔离,提高系统安全性,适合有隔离需求的信号/电源边界。
  • 开关频率 300kHz,有利于滤波器体积减小,且在 EMI 管理时较为可控。

四、应用建议

  • 通信设备的 48V 母线到 12V 点对点供电。
  • 工业控制模块、PLC 边缘单元及传感器供电。
  • 分布式电源系统、仪器仪表及嵌入式设备的隔离电源。
  • 需在有限空间内布置稳压、电隔离的场合。

五、设计与布局注意事项

  • 输入输出电容:建议在模块输入侧靠近引脚放置低 ESR 的电解或固态电容,并辅以陶瓷去耦以抑制高频噪声;输出侧建议选用符合最大容性负载 330µF 限制的电容,避免输出环路不稳定。
  • 散热:尽管效率较高,长期满载或高环境温度时仍需注意散热,建议在模块上方保持通风或在 PCB 上配备大面积铜箔散热通道。
  • 布线:输入与输出的粗短走线可降低寄生阻抗,接地应尽量以单点或短回路布局,减少共模噪声耦合。
  • EMC/滤波:若系统对 EMI 敏感,可在输入端增加共模电感和差模滤波器,同时注意接地回流路径。

六、可靠性与测试

URB4812S-10WR3 适用于工业级工作温度(-40℃~+85℃),并通过隔离电压测试与常见过流/短路保护验证。推荐在最终产品中进行温升和长期老化测试,以验证在实际工况下的稳定性与寿命。

七、选型与采购提示

  • 确认输入母线为稳定 48V,考虑启动/浪涌电压对模块的影响;如存在较大输入波动,应加入前置浪涌抑制或选择更宽输入范围的模块。
  • 输出要求若需更大电流或更低纹波,可考虑并联或更高功率等级的替代产品,并做好均流与热设计。
  • 购买时注意型号完整性(URB4812S-10WR3)与品牌(YLPTEC 易川),核对参数以确保符合系统要求。

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
