YLPTEC(易川)QA053C-1505R3是一款针对小功率双极性隔离供电场景设计的电源模块,核心围绕“双输出适配、高隔离防护、宽温宽压稳定”三大方向,解决传统单极性电源无法驱动运放、ADC等模拟电路的痛点,满足工业控制、医疗电子等领域对电源纯净度、安全隔离及环境适应性的需求。
QA053C-1505R3聚焦双极性隔离供电需求——即同时输出负电压(-5V)与正电压(15V),核心特性包括:
输入电压范围4.5V~5.5V,可直接由USB 5V、MCU稳压输出供电,无需额外升降压电路;双输出端分别提供:
5kVac隔离电压(持续1分钟),符合工业级隔离标准,有效抑制输入侧EMI传递至输出端,同时保护后端敏感电路免受高压冲击。
纹波噪声控制在50mVp-p(20MHz带宽),避免对模拟信号的干扰;最大容性负载达1000uF,可直接带载大容量滤波电容,无需额外缓冲电路,简化PCB设计。
开关频率200kHz(高于音频范围,无 audible噪声),结合宽温设计,高低温环境下输出电压波动小,长期运行可靠性高。
采用SIP-5直插封装,尺寸仅19.5mm(长)×9.8mm(宽)×12.5mm(高),体积小巧紧凑,适合空间受限的PCB布局(如小型传感器模块、便携式仪器);直插式引脚便于手工焊接与批量生产,降低组装难度。
QA053C-1505R3的双输出、高隔离特性,使其适配多领域场景:
总结:QA053C-1505R3是一款高性价比的双输出隔离电源模块,以紧凑体积实现双极性供电、高隔离防护与宽温稳定,是工业控制、医疗电子等领域的理想电源解决方案。
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.
