H2405S-1WR3 产品概述
H2405S-1WR3 是 YLPTEC(易川) 推出的一款小体积、高效率、隔离型微功率 DC/DC 模块。该器件为定电压、非稳压单路输出设计，输出 5V/200mA（1W），特别适合在板上电源系统中需要产生与输入电源电气隔离的小功率场合。
一、主要性能参数
- 输入电压：21.6V ～ 26.4V（建议 Vin 变化范围 ±10%）
- 输出电压：5V（定电压）
- 输出功率：1W，最大输出电流 200mA
- 转换效率：典型 89%
- 隔离电压：6kVrms（输入-输出）
- 纹波/噪声：30mVp-p（典型）
- 最大容性负载：2400µF
- 开关频率：100kHz
- 静态电流：1mA
- 工作温度：-40℃ ~ +85℃
- 封装/尺寸：SIP-4，19.5 × 9.8 × 12 mm
二、功能与保护特性
- 短路保护：支持短路防护并在故障消除后自动恢复输出，无需外部复位。
- 过热保护：内置过温保护，超过安全温度时进行保护并在温度恢复后自动恢复工作。
- 自动故障恢复：针对过载、短路、过温情况具有自动恢复能力，提高整机可靠性。
三、典型应用场景
- 需要输入输出电气隔离的小功率板载电源（隔离驱动、逻辑隔离等）。
- 纯数字电路、低频模拟电路、继电器驱动、数据交换接口、通信模块供电等。
- 工业控制、仪器仪表及需要高隔离等级的嵌入式系统中作为辅助电源使用。
四、设计要点与使用建议
- 输入电压应尽量稳定，建议在标称 Vin 的 ±10% 范围内工作，以保证输出稳定性。
- 为保证系统抗干扰与稳定，模块输出端仍建议并联适当的去耦电容（注意不超过最大容性负载 2400µF）。
- 在高温或满载工况下需注意散热与布局，避免长期在极限温度下运行导致寿命降低。
- 输出为非稳压类型，对输出电压精度要求高的模拟前端应避免直接使用，建议在数字或驱动场合优先采用。
- PCB 布局时保证输入、输出及地的分离走线，减少干扰耦合，且保持模块周围通风空间。
五、封装与选型提示
- SIP-4 小体积封装便于插针式安装或贴装在边缘插槽上，尺寸 19.5×9.8×12mm 适合板上高密度布局。
- 型号：H2405S-1WR3；品牌：YLPTEC(易川)。选型时请确认输入电压档位、输出功率与隔离等级满足系统需求。
总结：H2405S-1WR3 以其高效率、6kV 隔离能力和自动恢复保护，适合各种需要小功率隔离供电的场合。选用时请关注输入电压稳定性、容性负载限制与散热条件，以确保长期可靠运行。

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.
