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。
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。
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)。
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。
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。
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。
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。
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。
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。
E0505S-1WR3凭借特性优势,广泛适用于:
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。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
