B0303XT-1WR3 产品概述
一、产品简介
B0303XT-1WR3 是 YLPTEC(易川) 推出的一款小功率隔离型 DC-DC 转换器。该器件为定电压输入、隔离非稳压单路输出，额定输出功率 1W，面向对隔离要求较高、输入电源相对稳定且对输出精度要求不高的嵌入式与工业应用场景。封装为 SMD 小体积形式，适合空间受限的板级设计。
二、主要电气参数
- 输入电压范围：2.97 – 3.63 V（标称 Vin≈3.63 V）
- 输出电压：3.3 V（单路）
- 额定输出功率：1 W，最大输出电流 303 mA
- 峰值效率：可达 89%，典型转换效率约 77%
- 开关频率：约 220 kHz
- 最大容性负载：2400 μF
- 隔离电压：1500 VDC（可标示为 1.5 kV 级隔离）
- 空载电流：低至 3 mA
- ESD 抗扰度：接触放电 8 kV
三、保护与可靠性
- 持续短路保护：具备持续短路保护能力，并支持自动故障恢复（短路解除后自动恢复正常输出）。
- 工作/存储温度：常规工作温度范围 -40℃ ～ +105℃，部分规格或标注可达 -50℃ ～ +115℃（具体以出厂资料为准）。
- 隔离和抗扰能力适合需要输入/输出间电气隔离的系统，满足工业级使用要求。
四、机械与封装信息
- 尺寸：13.2 mm × 8.5 mm × 7.3 mm（长×宽×高）
- 封装形式：SMD，国际标准引脚方式，便于自动化贴装与批量生产。
五、典型应用场景
- 输入电压波动较小（±10% Vin）且需电气隔离的便携或固定式设备。
- 通信模块、电源前端隔离、信号采集前端、隔离传感器供电等对安全或地隔离有要求但对输出精度及低纹波要求不高的场合。
- 空间受限且需采用表面贴装工艺的工业与消费类电子产品。
六、使用建议与注意事项
- 该器件为非稳压隔离模块，输出在不同负载与输入条件下会有一定变化，不适合对电压稳定度和低纹波噪声有严格要求的敏感负载；必要时在输出端增加滤波/稳压电路。
- 推荐在输入端与输出端均配置相应旁路电容与 PCB 接地及走线优化，以降低 EMI 干扰并保证稳定工作。
- 在高温或高负载环境下，请参考厂家热特性与降额使用建议，避免长期接近极限工况。
本产品由 YLPTEC(易川) 提供，适合对隔离等级与小型化有明确需求的设计，在保证安全隔离的前提下提供高密度的 1W 输出能力。欲了解更详细的电气特性曲线、引脚定义与典型应用电路，请参考产品规格书或联系厂商技术支持。

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.
