B0505S-1WR2 DC-DC隔离电源模块产品概述

一、产品定位与核心功能
B0505S-1WR2是海凌科(HI-LINK)推出的1W小功率DC-DC隔离电源模块,核心作用是实现5V输入到5V输出的电气隔离,同时提供稳定直流供电。该模块针对小功率、高集成度场景设计,解决共地干扰、电压波动等问题,适用于工业控制、通信、仪器仪表等领域的隔离供电需求。

二、基础参数全面解析
模块核心参数直接决定适用场景,以下是关键参数的详细说明:

  1. 输入输出参数:

    • 输入电压(Vin):4.5V~5.5V,兼容标准5V电源(USB、电池、线性电源),可应对±10%电压波动,无需额外稳压;
    • 输出电压(Vout):5V稳压输出,最大电流200mA、额定功率1W,满足多数低功耗数字电路、传感器供电;
    • 纹波噪声:100mVp-p(峰峰值),符合数字电路纹波要求,无需复杂后级滤波。
  2. 隔离与效率参数:

    • 隔离电压(Vrms):1.5kV,符合IEC 60950安全标准,阻断输入输出端噪声(共地干扰、瞬态脉冲);
    • 转换效率:80%,输出1W时输入功率约1.25W,损耗低,适合长期连续工作;
    • 开关频率:100kHz,兼顾效率与EMI控制,无需额外EMI滤波。
  3. 其他关键参数:

    • 最大容性负载:220uF,支持后级大电容滤波,提升输出稳定性;
    • 工作温度:-40℃~+85℃,覆盖工业环境高低温波动;
    • 封装尺寸:11.5mm×6mm×10mm,体积小巧,适配紧凑空间。

三、核心性能特性

  1. 电气隔离抗干扰:1.5kV隔离电压有效阻断前后端噪声,避免电源干扰传递到负载(如传感器、MCU),提升系统可靠性;
  2. 宽压适应与保护:输入±10%波动仍稳定输出,内置短路保护——输出短路时自动切断电路,防止模块过热损坏;
  3. 宽温稳定工作:-40℃至+85℃无需温控组件,适合户外、车载等极端环境;
  4. 高集成易用性:SIP-4单列直插封装便于焊接,仅需少量输入输出电容即可工作,降低设计难度。

四、典型应用场景
B0505S-1WR2适配以下场景:

  1. 工业控制:PLC模块、传感器节点、小型控制器隔离供电,阻断现场电磁干扰(电机、变频器噪声);
  2. 通信设备:IoT节点、小型路由器、无线模块5V隔离供电,避免电源与通信端共地干扰;
  3. 仪器仪表:便携式测试设备、数据采集器供电,宽温满足户外测试需求;
  4. 汽车电子:车载小功率设备(行车记录仪、传感器)隔离供电,符合车载温压要求;
  5. 消费电子:小型医疗设备(血糖监测仪)、智能家居终端隔离供电,提升安全性。

五、可靠性与安全设计
模块内置短路保护,快速响应故障;1.5kV隔离电压满足安全标准,防止触电风险;宽温与高转换效率确保长期连续工作稳定性,适合批量应用。

总结
B0505S-1WR2以高集成、宽温适应、抗干扰强为核心优势,针对小功率隔离供电场景提供经济高效的解决方案。SIP-4封装与易用性设计,可快速集成到各类电子系统,是工业控制、通信、仪器仪表等领域的理想选择。

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
