B0505M-2WR3是YLPTEC(易川)推出的1通道小功率隔离电源模块,专为需要电气隔离、低功耗、紧凑集成的应用场景设计。以下从核心参数、性能特点、应用场景等维度详细概述该产品。
该模块参数覆盖输入输出、效率、隔离安全等关键维度,具体如下:
宽输入电压适应性
4.5V~5.5V的输入范围覆盖5V电源的典型波动(如USB电压降、线性电源误差),无需额外稳压电路即可稳定工作,提升系统兼容性。
高转换效率与低功耗
88%的转换效率高于同类小功率模块平均水平,减少电源损耗及模块发热,尤其适合便携/嵌入式系统(如电池供电设备)。
低纹波噪声输出
30mVp-p的纹波远低于普通开关电源,可直接为模拟电路、传感器、ADC/DAC等敏感器件供电,无需额外滤波,简化系统设计。
完善的安全保护
内置短路保护机制,负载短路时自动关断,故障排除后自动恢复,避免模块及后端负载损坏,提升系统可靠性。
宽温与大容性负载
-40℃~+85℃适应工业环境(户外设备、车间控制器);2400uF容性负载可直接驱动大容量滤波电容,确保输出稳定,减少瞬态波动。
该模块凭借紧凑尺寸、隔离特性及宽温适应性,广泛覆盖以下领域:
采用SIP-4单列直插封装,引脚布局简洁,支持手工/自动化插件安装;11.5×7.5×10mm的紧凑尺寸适合高密度PCB布局,额定功率2W下发热低,无需额外散热片,进一步节省系统空间。
YLPTEC(易川)对该模块进行严格可靠性测试(高低温循环、振动、老化),确保恶劣环境下长期稳定;1.5kV隔离电压符合IEC 60950安全标准,短路保护等功能经实际负载验证,品质可靠。
总结:B0505M-2WR3以高性价比、紧凑集成、完善性能及安全特性,成为中小功率隔离电源需求的理想选择,覆盖工业、通信、消费电子等多领域应用。
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.
