WRA1205S-3WR2 产品概述
一、产品简介
WRA1205S-3WR2 是 YLPTEC（易川）推出的一款高密度隔离型双输出DC-DC模块，采用 SIP-7 小型封装，专为空间受限的工业与嵌入式系统设计。模块输入电压范围宽（9V～18V），输出为 ±5V 双轨，额定输出功率 3W，单路最大输出电流 300mA，适合为模拟控制电路、数据采集与隔离信号链供电。
二、主要性能参数
- 输入电压（Vin）：9V ～ 18V
- 输出电压（Vout）：±5V（双输出）
- 输出功率：3W（总功率）
- 单路最大输出电流：300mA
- 转换效率：典型 78%（满载）
- 隔离电压（Vrms）：1500V（1.5kV）
- 开关频率：300kHz
- 纹波噪声：≤100mVp-p
- 最大容性负载：1000µF
- 工作温度：-40℃ ～ +85℃
三、保护特性与可靠性
模块具备短路保护、欠压保护与过流保护，并支持自动故障恢复（hiccup 或自动重试机制），可在异常工况下限制损坏并尽快恢复供电。高达 1.5kV 的输入输出隔离能力能有效阻断地回路干扰，提升系统可靠性。工作温度覆盖工业级范围，适合恶劣环境应用。
四、封装与机械特性
- 封装形式：SIP-7（直插）
- 外形尺寸：长度 22mm × 宽度 9.5mm × 高度 12mm
紧凑的 SIP-7 封装便于在 PCB 上串联布置或插装到背板，适用于体积受限的模块化系统。模块热损耗需通过合理的 PCB 散热与通风设计来控制，以保证高温环境下的可靠运行。
五、应用场景
WRA1205S-3WR2 适用于：
- 工业控制与自动化设备的隔离供电
- 仪表与数据采集前端供电（模拟与数模混合场合）
- 通信设备、传感器节点及低功耗分布式电源系统
- 需要电气隔离以抑制地环路或满足安全要求的嵌入式系统
六、使用建议
- 输出端建议并联适量去耦电容以降低纹波，单路容性负载不超过 1000µF；超大电容会引发启动或保护动作。
- 满载时转换效率约 78%，对应热损耗约 0.8～1W，应在 PCB 布局时预留散热路径并避免密集元件覆盖模块顶部。
- 输入侧建议加装滤波与浪涌抑制元件以提高抗扰度；当用于敏感模拟链路时，可在输出端加小值并联陶瓷电容以降低高频噪声。
- 在需要更高隔离或认证的系统中，请结合系统级安全/EMC 测试结果选择适配方案。
WRA1205S-3WR2 凭借其小巧体积、双轨输出与完善保护功能，是需要隔离、稳压与可靠性的工业与嵌入式电源方案的理想选择。若需详细电气参数图、引脚定义或典型接线图，请联系 YLPTEC（易川）获取完整资料。

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.
