B0505S-3WR2 产品概述

一、产品简介

B0505S-3WR2 是 YLPTEC(易川)推出的一款单路隔离型 DC‑DC 降压转换器,额定输出功率 3W,输入电压范围窄而稳定(4.5V–5.5V),输出为 5V/600mA。模块采用 SIP 封装(19.7×7mm),体积小巧,适合 PCB 直接插装与紧凑型系统应用。

二、主要规格

  • 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):600mA
  • 输出功率:3W
  • 转换效率:87%(典型)
  • 隔离电压 Vrms:1.5 kV
  • 最大容性负载:2400 µF
  • 纹波噪声:80 mVp‑p
  • 开关频率:250 kHz
  • 空载输入电流:6 mA
  • 保护特性:短路保护
  • 工作温度:-40 ℃ ~ +85 ℃
  • 尺寸:长 19.65 mm × 宽 10.16 mm × 高 7 mm
  • 封装:SIP,19.7×7 mm

三、主要特点

  • 高隔离性:1.5 kV RMS 隔离,适合需要信号/电源隔离的工业与测量领域。
  • 小体积高效率:在 3W 输出下可达 87% 的转换效率,节省系统功耗并降低热负荷。
  • 容性负载能力强:支持最高 2400 µF 的输出容性负载,兼容大电容滤波或耦合电容场合。
  • 可靠保护:内置短路保护,增强系统稳定性与安全性。
  • 宽温域工作:-40 ℃ 到 +85 ℃,适应恶劣环境。

四、典型应用

  • 工业控制与现场仪表
  • 通信设备的隔离电源
  • 数据采集与测量系统
  • 电池供电与便携设备(需注意输入限值)
  • PCB 插装型隔离电源模块

五、使用建议

  • 输入端建议并联 10–100 µF 低 ESR 电容以稳定输入并抑制突变电流。
  • 输出端根据纹波与响应要求配置合适的滤波电容,注意最大容性负载不得超过 2400 µF。
  • 布局时尽量缩短输入/输出的电源回路,接地端宜靠近模块引脚集中布线,减少环路干扰。
  • 若长期满载工作,确保良好散热与通风,必要时在模块周围留出空气流通空间或采用散热片辅助散热。
  • 遇到短路或过载,模块保护会动作,排查清除故障后可恢复工作。

六、封装与安装

SIP 插装封装(19.7×7 mm),厚度 7 mm,便于在标准 PCB 孔位直接焊接。安装时注意方向与焊接温度,避免过长时间的高温回流以保障可靠性。

七、选型与采购

型号:B0505S-3WR2,品牌:YLPTEC(易川)。选型时确认系统输入电压稳定在 4.5–5.5V 范围内并预留足够的散热和滤波空间。如有特殊隔离等级或工作温度需求,可与供应商沟通定制或选型更高规格产品。

如需进一步的电气图、引脚定义或典型应用电路,可提供电路参考与 PCB 布局建议。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
