A2405S-2WR3 产品概述

A2405S-2WR3(品牌:YLPTEC/易川)是一款小体积、高效率的隔离型微功率 DC/DC 模块,采用 SIP 封装,提供 ±5V 双路输出,适用于板上需要与输入电源隔离且对输出精度要求不高的场合。该模块以紧凑尺寸、全面保护与良好隔离性能为特点,便于直接嵌入各种数字和低频模拟电路、继电器驱动及数据交换电路等应用。

一、主要电气性能

  • 输入电压(Vin):21.6V ~ 26.4V(典型 24V 工况)
  • 输出电压(Vout):±5V(双路隔离输出)
  • 输出电流(最大):两路分别可达 200mA 和 10mA(请根据具体选型表确认具体分配)
  • 输出功率:总功率约 2W
  • 转换效率:典型 88%
  • 开关频率:100kHz
  • 纹波噪声:≤30mVp-p
  • 最大容性负载:1200µF(注意并联大电容对启动与稳定性的影响)

二、绝缘与环境特性

  • 隔离电压(Vrms):1500V(1.5kV)隔离等级,适合输入与输出之间的安全隔离需求
  • 工作温度范围:-40℃ ~ +85℃,适应工业级环境
  • 封装尺寸(L×W×H):19.5mm × 7mm × 10mm(SIP)

三、保护与可靠性

  • 短路保护:模块内置短路保护机制,遇短路能限制输出并避免损坏
  • 自动故障恢复:故障消除后模块可自动恢复正常工作,无需人工干预
  • 过热保护:当内部温度超过限值时进入保护状态,防止热失控
    这些保护功能提高了系统的可靠性,尤其适合长期连续工作的板上电源设计。

四、典型应用场景

  • 板上隔离电源需求:当主电源稳定(±10%Vin)且需提供一组与主电源隔离的参考电压时
  • 纯数字电路及一般低频模拟电路的供电/参考源
  • 继电器驱动电路、数据交换接口及隔离采集前端
  • 需要小体积、低功耗、高隔离但对输出精度要求不高的嵌入式系统

五、使用建议与注意事项

  • 输入电源应保持在额定范围内(21.6V–26.4V);超过范围可能影响效率和可靠性。
  • 输出旁路电容选型:虽允许较大容性负载(最大 1200µF),但建议在输出端并联低 ESR 的陶瓷或钽电容以降低纹波并改善瞬态响应;避免在启动时出现过大冲击电流。
  • 布局与散热:SIP 小体积需注意周围元件热量集中,保持模块周围一定空气流通或热传导路径,确保工作温度在安全范围内。
  • 隔离安全:若用于高压系统,请按相关标准设计隔离间距与爬电距离,模块标称隔离电压为 1.5kV RMS。
  • 若对输出稳定度或噪声有较高要求,建议在模块输出增加额外稳压或滤波电路。

A2405S-2WR3 以其小巧尺寸、较高效率和全面的保护特性,适合用于对隔离、可靠性和体积有严格要求的工业与嵌入式应用。选型时请参考厂家详细规格书以确认输出电流分配及其他参数的具体限制。

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
