A0503S-1WR3 产品概述
一、产品简介
A0503S-1WR3 是易川（YLPTEC）推出的一款双通道降压型隔离DC-DC模块，输入电压范围为 4.5V 至 5.5V，提供 ±3.3V 对称输出，额定总输出功率 1W。模块采用 SIP 封装，体积小巧（19.5 × 6 × 10 mm），适合空间受限、需隔离供电的工业及通信类应用。
二、主要特性
- 双通道隔离输出，输出电压 ±3.3V，满足正负电源需求；
- 总输出功率 1W，转换效率典型 80%；
- 宽输入范围：4.5V ~ 5.5V；
- 隔离耐压：1.5 kV (Vrms)，适用于需要基本隔离的场合；
- 具短路保护功能，提高系统可靠性；
- 工作温度范围：-40℃ ~ +85℃，适应严苛环境；
- 开关频率：100 kHz，纹波噪声 ≤ 30 mVp-p；
- 最大容性负载可达 1200 μF。
三、电气参数要点
- 输出电压：±3.3V（双通道）；
- 输出电流（最大值）：两个通道的典型可用电流分别为 152 mA 与 15 mA（总输出受限于 1W 功率预算）；
- 转换效率：约 80%（实际效率随负载与输入电压略有变化）；
- 纹波噪声：约 30 mVp-p（典型条件）；
请在系统设计时按功率预算与散热条件合理分配各通道负载，避免单通道过载。
四、封装与机械尺寸
- 封装形式：SIP（单列直插）；
- 外形尺寸：长 19.5 mm × 宽 6 mm × 高 10 mm，便于在 PCB 上并排布置与节省空间。
建议在布局时预留足够的走线与间距以保证隔离和散热。
五、典型应用场景
- 工业控制与传感器供电（需要隔离的模拟/数字电路）；
- 通信设备的电平隔离；
- 仪表仪器、数据采集模块的分立电源；
- 便携式或嵌入式系统中对小功率隔离供电的场合。
六、设计与使用建议
- 输入端建议使用 10 μF 左右的低 ESR 电容进行去耦，减少输入纹波；
- 输出端在需要低纹波时并联适当低 ESR 的电容，单通道容性负载不超过 1200 μF；
- 若靠近敏感模拟电路，应考虑增加 LC 过滤或屏蔽以抑制开关噪声；
- 在高温或接近最大功率条件下应考虑散热和降额使用，以保证长期可靠性。
七、可靠性与保护
模块具备短路保护功能，有利于防止意外短路导致的组件损坏；同时在设计时仍需考虑过流、过温等系统级保护策略。易川（YLPTEC）提供一致性的制造与质量控制，适合量产应用。

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.
