B0503S-3WR2 产品概述
一、产品简介
B0503S-3WR2 是 YLPTEC（易川）推出的一款高可靠性、小体积的隔离型直流-直流变换器，专为分布式电源系统中需要产生一路与输入电源隔离的电源场合而设计。该模块输入电压范围窄且稳定，输出功率为 3W，适合对体积、隔离与电磁干扰有严格要求的嵌入式与通信设备。
二、主要技术参数
- 输入电压（Vin）：4.5V ~ 5.5V
- 输出电压（Vout）：3.3V
- 输出通道数：1 路
- 输出功率：3W
- 输出电流（最大）：909mA
- 转换效率：82%（典型）
- 最大容性负载：2400µF
- 隔离电压（Vrms）：1500V
- 开关频率：250kHz
- 静态电流：6mA
- 纹波噪声：80mVp-p
- 工作温度：-40℃ ~ +85℃
三、功能特性
- 内置短路保护，保证在异常负载或短路条件下模块和系统的安全性。
- 低静态电流设计，有利于待机与低功耗场景使用。
- 低纹波与低噪声输出，适合驱动纯数字电路及一般低频模拟电路。
- 高隔离等级（1.5kVrms），满足工业与通信设备的安全隔离要求。
四、典型应用场景
- 分布式电源系统的隔离供电模块。
- 纯数字电路与微处理器供电。
- 继电器驱动电路、数据交换与通信接口电源。
- 工业控制与仪器仪表中需要隔离的接口或采集模块。
五、封装与机械特性
- 封装形式：SIP-4（单列直插封装）
- 外形尺寸：长 19.65mm × 宽 10.16mm × 高 7mm
- 安装方式便于模块化设计和批量生产，适用标准插孔或焊接固定。
六、设计与使用建议
- 输入端建议并联适当滤波电容，抑制输入端的瞬态干扰；输出端在驱动大容性负载时注意启动冲击电流。
- 在靠近敏感模拟电路时做好接地与屏蔽，以利用其低噪声特性。
- 预留足够散热空间，尽管功率仅 3W，但在高环境温度或封闭空间中仍需注意热管理。
- 可根据客户需求定制特殊规格（如更宽温度范围或不同电压输出），详情请联系 YLPTEC 技术支持。
B0503S-3WR2 以小体积、高隔离、稳定输出和完善保护功能，适配多类需要可靠隔离电源的场景，为系统设计提供稳固的电源解决方案。

Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
