QA01C-18是一款双路输出隔离电源模块,核心参数针对12V系统实际工作场景优化,无需额外稳压即可直接接入:
支持-40℃~+105℃的工作温度,完全匹配户外设备、车间高温/低温场景(如北方冬季户外、南方车间高温),无需额外保温/散热措施,可靠性更高。
内置短路保护电路,当输出端发生短路时,自动限制电流或切断输出;故障排除后可自恢复,避免模块损坏,提升系统稳定性(无需手动重启,减少维护成本)。
最大容性负载220uF,可直接连接后端大滤波电容,进一步降低输出纹波,适配不同负载的启动需求(如电机驱动、电容性负载设备)。
开关频率95kHz(处于音频范围外),减少电磁干扰(EMI),无需额外EMI滤波即可满足一般工业/通信设备的电磁兼容要求。
采用SIP-5直插封装,尺寸仅19.5mm(长)×9.8mm(宽)×12.5mm(高),体积小巧,适合集成到:
直插封装安装方便,可通过通孔焊接或插座连接,降低装配难度。
3.5kVrms的AC隔离电压,满足GB/T 13028等标准要求,实现输入输出电路的电气隔离:
QA01C-18的参数特性使其适配多个实用场景:
QA01C-18是一款专为低压双输出隔离供电设计的高性价比模块,紧凑尺寸、宽温工作、短路保护与高隔离电压等特性,使其成为工业控制、通信、车载等场景中小功率双电源需求的可靠选择,无需复杂外围电路即可快速集成。

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.
