H2409S-2WR3 产品概述

一、产品简介

H2409S-2WR3 是 YLPTEC(易川) 推出的一款小体积、高效率的定电压、隔离型非稳压单路 DC/DC 模块。模块针对板上需要从 24V 档电源衍生出与输入电源隔离的 9V 电源的场合设计,具有体积小、效率高、保护功能完善的特点,适合嵌入式系统、通信和一般数字电路的隔离供电需求。

二、主要电气参数

  • 输入电压:21.6V ~ 26.4V(针对稳压或±10% Vin 场合)
  • 输出电压:9V(定电压)
  • 输出功率:2W,最大输出电流 222mA
  • 转换效率:89%(典型)——输出 2W 时,模块自身耗散约 0.24W 左右
  • 隔离电压:6kV (Vrms)
  • 开关频率:100kHz
  • 静态电流:5mA
  • 纹波噪声:70mVp-p(典型)
  • 最大容性负载:1000µF

三、功能与保护

模块内置短路保护、自动故障恢复与过热保护。发生短路或过载时模块自动限流或进入保护状态,排除故障后可自动恢复,增强系统可靠性。工作温度范围为 -40℃ 至 +85℃,适应工业级环境。

四、典型应用场景

适用于需要输入/输出电隔离、对输出精度要求不高且输入电压稳定的场合,例如:

  • 纯数字电路供电隔离
  • 继电器驱动电源
  • 数据交换与通信接口供电
  • 一般低频模拟电路(对噪声要求不严的场合)

五、设计与使用建议

  • 输入:建议在模块输入端并联高品质去耦电容(如低 ESR 电解电容与陶瓷电容组合),以抑制开关噪声并提高系统稳定性;确保输入电压在 21.6–26.4V 范围内。
  • 输出:模块允许的最大容性负载为 1000µF,超大电容可能影响启动特性和稳定性,需谨慎验证。对于突发瞬态负载,建议在输出端靠近模块放置陶瓷去耦电容。
  • 散热与布局:模块效率高且功耗小,但在高环境温度或密闭空间内仍需考虑散热与通风,保证过热保护有余量。布线时注意输入/输出线短而粗,以降低寄生阻抗与噪声耦合。
  • EMC 与滤波:如系统对电磁兼容或输出噪声敏感,可在输入端加 L、C 滤波网络并做好接地处理。

六、机械与环境

  • 外形尺寸(SIP 封装):19.5 × 9.8 × 12.5 mm,适合板上直插或插座安装。
  • 工作温度:-40℃ 至 +85℃,环境适应性强。

七、总结

H2409S-2WR3 以其紧凑体积、接近 90% 的高效率、良好的隔离性(6kV)和完善的保护功能,适合在板上为数字电路、继电器驱动和数据接口等场景提供小功率隔离 9V 电源。按照建议的去耦与布板方法使用,可在工业级环境中获得稳定可靠的工作表现。若需批量应用或特殊工况验证,建议依据实际负载与温度条件进行系统级测试与评估。

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
