E0505S-1WR3 电源模块产品概述

一、核心参数总览

E0505S-1WR3是YLPTEC(易川)推出的小功率隔离双极性电源模块,核心参数精准匹配工业、医疗等场景需求:

  • 输入输出:输入电压范围4.5V~5.5V(兼容5V电源波动),双路对称输出±5V;
  • 功率效率:额定输出功率1W,转换效率达88%(低损耗发热小);
  • 电流能力:单路最大输出电流±100mA(双路总功率1W,匹配5V×100mA×2的设计);
  • 隔离特性:隔离电压3kVrms(满足高安全隔离需求);
  • 负载与噪声:最大容性负载1200uF(稳定驱动大电容),纹波噪声30mVp-p(低干扰);
  • 物理规格:SIP单列直插封装,尺寸19.5mm×6mm×10mm(小体积易集成)。

二、关键性能优势

1. 宽输入电压适配

输入覆盖4.5V~5.5V,兼容电池放电后期(如3节AA电池≈4.5V)、5V适配器电压偏差,无需额外稳压电路即可稳定工作,简化系统设计。

2. 双极性对称输出

提供±5V双路输出,完美匹配运放、差分信号调理、传感器前端等双极性供电需求——输出电压对称性好,避免单路供电导致的信号偏移问题,提升模拟电路精度。

3. 高效能低功耗

88%的转换效率减少了功率损耗,模块发热极低,无需额外散热片/风扇,适合小体积、低功耗设备(如便携式仪器)。

4. 低噪声稳定输出

30mVp-p的纹波噪声远低于普通电源模块,对高精度信号采集、医疗传感器等敏感电路友好,可有效降低噪声干扰,保证信号还原度。

5. 高隔离安全可靠

3kVrms的隔离电压满足工业控制、医疗设备的安全标准,可隔离前后级电路的共地干扰、防止高压串扰,提升系统抗干扰能力与安全性。

三、封装与安装特性

采用SIP单列直插封装,尺寸仅19.5mm×6mm×10mm,可直接焊接在PCB板上,安装便捷;小体积适合空间紧凑的设备(如手持医疗仪器、小型工业控制器),不占用额外布局空间。

四、可靠性与环境适应性

1. 宽温工作范围

工作温度覆盖-40℃~+85℃,可适应户外低温、工业车间高温等恶劣环境,无需温控措施,提升设备环境适应性。

2. 大容性负载能力

最大容性负载1200uF,可稳定驱动滤波电容、储能电容(如传感器前端的大电容滤波),输出电压波动小,适合对负载突变敏感的场景。

3. 内置短路保护

模块内置短路保护机制:当输出端短路时,自动切断输出,避免模块损坏及系统故障,提升产品使用寿命与可靠性。

五、典型应用场景

E0505S-1WR3凭借特性优势,广泛适用于:

  • 工业传感器调理:双极性输出适配运放,高隔离保护传感器信号免受干扰;
  • 便携式医疗设备:宽温、3kV隔离符合医疗安全标准,小体积适合手持设备;
  • 小型工业控制器:5V输入适配常见控制器电源,低噪声保证控制精度;
  • 模拟信号采集:30mVp-p低噪声提升数据采集精度,适合高精度测试仪器;
  • 通信接口电路:隔离功能避免接口间共地干扰,提升RS485、CAN等通信稳定性。

总结

E0505S-1WR3是一款高性价比、小体积隔离电源模块,兼具宽输入范围、双极性输出、高隔离、低噪声等核心优势,精准匹配工业、医疗、通信等领域的紧凑设计需求,是替代传统线性电源的理想选择。

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
