B0505S-1WR2 产品概述
一、概述
B0505S-1WR2 是 YLPTEC（易川）推出的一款单通道隔离型 DC-DC 模块，额定输出功率 1W，输入电压范围 4.5V～5.5V，输出稳定 5V。模块体积小巧、效率高、具备短路保护和良好的隔离特性，适用于对信号或电源需要隔离的小功率场合。
二、主要参数
- 通道数：1
- 输入电压（Vin）：4.5V ～ 5.5V
- 输出电压（Vout）：5V
- 输出电流（最大）：200mA（1W）
- 转换效率：典型 88%
- 最大容性负载：220µF
- 隔离电压（Vrms）：1.5kV
- 纹波噪声：30mVp-p（典型）
- 开关频率：270kHz
- 工作温度：-40℃ ～ +105℃
- 特性：短路保护
- 封装：插件（通孔）
- 尺寸：11.6mm × 6mm × 10.16mm
三、产品特点
- 高效率：典型转换效率可达 88%，减小功耗与发热。
- 良好隔离：1.5kVrms 隔离等级，能有效抑制共模干扰，提升系统安全性与抗扰能力。
- 小体积、插件式封装：便于传统 PCB 板级安装与维护。
- 抗短路：内置短路保护，异常时对模块和负载提供基本保护。
- 宽温度范围：-40℃ 至 +105℃，适应野外与工业环境。
四、典型应用场景
- 工业控制与现场总线隔离电源
- 微控制器与传感器之间的信号/电源隔离
- 数据采集、测量设备的隔离供电
- 通信接口（如 RS-232/485）的小功率隔离
- 仪器仪表与模块化系统的板间供电隔离
五、封装与安装注意
- 插件（通孔）封装，尺寸 11.6×6×10.16mm，适合标准 PCB 布局。
- 建议在输入侧并联适当的去耦电容以抑制输入瞬变；输出侧根据最大容性负载要求选择低 ESR 电容，避免超出 220µF。
- 模块存在热耗散，若长时间满载或高温环境下应考虑散热或降额使用。
- 保持隔离区周边清洁，避免导电残留物影响隔离耐压性能。
- 非设计用作直接对交流主电网隔离，请在系统设计时按应用场景评估安全等级要求。
六、选型与使用建议
- 若系统需较高隔离电压或更高功率，请选择更高等级或更大功率的器件。
- 在高 EMI 环境中，建议配合输入滤波与屏蔽措施，充分考虑地线与接地策略。
- 了解短路保护的具体工作方式（自动恢复或需要人工复位），以便在系统故障处理时采取合适措施。
B0505S-1WR2 以其小体积、高效率和可靠的隔离性能，适合多种工业与嵌入式应用。选型时请结合实际工作条件（温度、散热、负载特性与隔离需求）进行全面评估。若需详细引脚图或电气特性曲线，请联系供应商或参考官方规格书。

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.
