H2405S-2WR3 产品概述
一、产品简介
H2405S-2WR3 是 YLPTEC(易川) 推出的微小功率、隔离型单路 DC/DC 模块。该模块体积小巧（SIP 封装：19.5×9.8×12.5 mm），针对板上需要与输入电源隔离的应用设计，提供 5V 定电压输出，最大输出功率 2W，适合产生一组隔离电源以驱动数字电路、继电器、数据交换接口等场合。
二、主要电气规格
- 输入电压：21.6V ～ 26.4V（典型工作区间 ±10% Vin）
- 输出电压：5.0V（非稳压型，定电压输出）
- 输出电流：最大 400mA（2W）
- 转换效率：典型 88%
- 隔离电压：6kV (Vrms)
- 纹波噪声：70 mVp-p（典型）
- 最大容性负载：2400 μF
- 开关频率：100 kHz
三、功能与保护
- 短路保护：限流或折返保护，短路后可自动恢复（无需人工复位）
- 过热保护：内部温度异常时进入保护状态，保护器件可靠性
- 自动故障恢复：故障解除后模块会自动恢复正常输出
四、应用场景
- 板载隔离电源：当系统主电源稳定且需生成隔离供电给小功率子系统时
- 纯数字电路、逻辑隔离、继电器驱动、数据交换接口等
- 低频模拟场合（对输出精度要求不高） 注意：若需要高精度稳压或更低噪声，应在模块输出侧增加线性稳压器或滤波网络。
五、使用建议与注意事项
- 输入电压建议保持在标称范围内（21.6–26.4V），超过范围会影响稳定性与寿命
- 由于为非稳压隔离模块，输出受输入与负载影响；对精密设备建议二次稳压或局部 LDO
- 输出侧并联大电容（不超过 2400 μF）可稳定瞬态响应，但请注意电容 ESR 对启动行为的影响
- 如需降低 EMI，建议在输入端加 LC 滤波器、在输出端加适当去耦电容与磁环滤波
- 高温环境下应考虑散热与功率降额，保证工作温度在 -40℃～+85℃ 之间
六、机械与封装
- 封装形式：SIP，尺寸 19.5 × 9.8 × 12.5 mm，便于板上直插安装，节省 PCB 面积
- 安装时建议保留周围足够空间以利散热，并避免强烈振动或机械应力
七、型号与选型建议
- 型号：H2405S-2WR3（YLPTEC / 易川）
- 选型时确认输入母线电压稳定且在允许范围内；如需更高输出精度或更大功率，应选择带稳压或更高功率等级的系列产品
H2405S-2WR3 凭借小体积、高效率、6000Vrms 隔离能力及完善的保护功能，适合在对隔离、安全性和板级集成度有要求的嵌入式系统中作为经济可靠的隔离供电解决方案。

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.
