QA053C-1803R3 产品概述
校验通过!
一、产品简介
QA053C-1803R3 是 YLPTEC(易川) 出品的双路隔离DC-DC转换器，SIP-5 封装，针对紧凑型隔离供电场景设计。输入电压范围为 4.5V~5.5V，提供双路输出：+18V 与 -3.5V，单路最大输出电流可达 80mA，转换效率典型值 82%。模块体积小（19.5 × 9.8 × 12.5 mm），适合板端直插应用。
二、主要性能亮点
- 双输出：+18V 与 -3.5V，便于为模拟前端、运算放大器或隔离测量模块提供对称与参考电源。
- 隔离性能：隔离电压 5kV RMS，适用于工业系统或信号隔离需求。
- 保护与可靠性：内置短路保护并支持自动故障恢复，提高系统稳定性与可维护性。
- 工作环境：宽温范围 -40℃ ~ +105℃，适应严苛工业环境。
- 电性能：开关频率 200kHz，纹波噪声约 50mVp-p，可配合小型滤波网络降低输出噪声。
三、典型应用场景
- 工业控制与仪表：为隔离放大器、数据采集模块提供独立高电压与负电源。
- 通信接口：为隔离型收发器、光电隔离器等器件供电。
- 医疗设备（非直接诊断/治疗主电路需遵循相关认证）：用于信号隔离与低功耗前端供电。
- 测试与测量：为差分测量电路或精密采样电路提供稳定参考电源。
四、使用与设计建议
- 输入侧建议使用低等效串联电阻(ESR)的滤波电容，靠近模块引脚布置以抑制输入纹波。
- 输出侧最大容性负载支持 680µF，但建议分级滤波，使用低ESR电容并注意电容耐压与极性。
- 考虑到模块总输出约 1.7W 左右（两路满载），按典型效率 82% 计算，内部热量有限但仍建议在高环境温度或封闭空间中留有散热空间或适当通风。
- 采用隔离传输信号时，确保系统地线与隔离边界的布线清晰，避免形成共模干扰回路。
- 如系统要求更高的EMI性能，可在输入端加入共模滤波器或在输出端增加π型滤波。
五、机械与封装
SIP-5 直插封装，尺寸 19.5 × 9.8 × 12.5 mm，适合单面插件或混合插件PCB设计。小尺寸有利于密集布局，但焊接时注意温度曲线以保护内部元件。
六、选型注意事项
- 确认输入电压稳定在 4.5V~5.5V 范围内以避免工作异常。
- 根据负载动态特性和启动顺序评估是否需要外加软启动或限流保护。
- 如需通过认证（如医疗、车规或某些工业标准），请选择相应认证型号或与厂商确认相关合规性。
QA053C-1803R3 以其高隔离电压、小体积与自动恢复保护特性，适合用于需要双极电源与隔离保护的中低功率嵌入式与工业应用。若需引脚定义、电气特性曲线或典型电路图，请提供进一步信息，将为您提供详细选型与接线建议。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
