B1203S-1WR3 产品概述

一、产品简介

B1203S-1WR3 为 YLPTEC(易川)推出的一款单通道降压型直流-直流隔离式变换器,额定输出功率 1W,专为 12V 系统(工作电压范围 10.8V–13.2V)降压到 3.3V 小功率负载而设计。器件采用 SIP-4 封装,体积小、安装方便,适合工业控制、通信终端与嵌入式系统的电源隔离与电压转换需求。

二、主要电气参数

  • 输入电压范围:10.8V ~ 13.2V(典型 12V)
  • 输出电压:3.3V
  • 最大输出电流:303mA(1W)
  • 转换效率:典型 84%
  • 开关频率:260kHz
  • 空载输入电流:8mA
  • 纹波噪声:30mVp-p(典型)
  • 最大容性负载:2400µF
  • 隔离电压:1.5kVrms
  • 工作温度范围:-40℃ ~ +105℃
  • 保护功能:短路保护

三、关键特性与可靠性

器件具备较高隔离等级(1.5kVrms),适用于需要地线隔离或信号隔离的场合;短路保护提高系统可靠性,避免因意外短路导致电源与负载受损。260kHz 的开关频率在体积与EMI控制间取得平衡,有利于采用小型磁性元件与滤波器设计。宽温工作范围使其适合工业级应用。

四、典型应用场景

  • 工业控制模块与传感器供电
  • 通信设备辅助电源与信号隔离
  • 嵌入式单板及仪表供电
  • 需要隔离的低功率子系统(3.3V 数字电路、ADC/DAC 参考电源等)

五、设计与使用注意事项

  • 输入端建议并联陶瓷(0.1µF)与低 ESR 电解/钽电容(≥10µF)以抑制瞬态与开环振荡;输出端建议配置低 ESR 电容,注意不超过最大容性负载 2400µF。
  • 为降低纹波与 EMI,尽量缩短输入到模块的走线,输入/输出地线分层布线并在模块附近形成固体回流路径。
  • 在高温或高负载工况下应考虑热沉或散热空间,必要时对输出电流进行适当降额以保证可靠性。
  • 虽有短路保护,但长时间异常负载仍可能影响寿命,应在系统层面增加监测与保护措施。
  • 隔离侧接地应根据系统安全策略正确配置,避免不必要的接地环路。

六、封装与订购信息

  • 封装形式:SIP-4(单列直插)
  • 品牌:YLPTEC(易川)
  • 型号:B1203S-1WR3
    购买或设计集成时,请参考厂商详尽数据手册以获取典型特性曲线、引脚定义、热阻参数与推荐 PCB 布局图。校验通过,适用于对体积、隔离与可靠性有明确要求的低功耗转换场合。

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
