B0303S-1WR2 产品概述

一、产品简介

B0303S-1WR2 是 YLPTEC(易川) 推出的单通道隔离型直流变换模块,额定输出功率 1W,采用插件封装,适用于需要小型隔离电源的场合。模块输入电压范围为 2.97V ~ 3.63V,输出稳压 3.3V,最大输出电流 303mA,具有高可靠性和实用的保护功能,适配各种嵌入式与工业控制系统。

二、主要性能与电气参数

  • 输入电压 Vin:2.97V ~ 3.63V
  • 输出电压 Vout:3.3V(固定)
  • 输出功率:1W,最大输出电流 303mA
  • 转换效率:典型 72%
  • 开关频率:220kHz
  • 空载输入电流:10mA
  • 纹波噪声:30mVp-p(负载条件下典型值)
  • 最大容性负载:220µF
  • 隔离电压 Vrms:1.5kV

以上参数为典型值或最大值,实际使用时请参考具体工作点下的特性曲线与热设计条件。

三、保护与可靠性

模块具备短路保护功能,能在异常负载或短路时限制输出,保护负载与模块自身安全。工作温度范围宽(-40℃ ~ +105℃),适应工业级环境。由于效率为72%左右,在高负载条件下仍会产生一定热耗散(示例:在满载且按额定功率输出时,器件损耗约为0.39W),建议在设计时预留散热空间或采用通风/散热片等措施以保证长期可靠性。

四、应用场景

适用于需要隔离的小功率电源场合,包括但不限于:

  • 工业控制信号隔离与传感器前端供电
  • 数据采集模块与隔离通信接口
  • 电池供电或便携设备中需要隔离的模块供电
  • 仪器仪表、楼宇自动化与通讯设备的局部隔离电源

五、典型应用建议与封装信息

  • 推荐在输出端并联低等值的去耦电容以抑制纹波,注意不超过最大容性负载 220µF。
  • 输入侧应采用良好滤波与布局,尽量缩短高频回路走线,减小 EMI。
  • 满载工作时注意热管理,尽可能保持周围环境温度并留有通风空间。
  • 封装:插件(through-hole),便于安装与手工焊接,适合小批量或现场维护替换。
  • 品牌型号:YLPTEC(易川) B0303S-1WR2。

总结:B0303S-1WR2 为一款性能均衡、具有隔离与短路保护的小功率 DC-DC 模块,适合对体积、隔离要求较高且功耗在 1W 范围内的应用场景。若需进一步的引脚定义、典型电路或测评数据,可提供具体应用需求以便给出更详细的设计建议。

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
