WRA1209S-3WR2 产品概述
一、产品简介
WRA1209S-3WR2 是 YLPTEC（易川）推出的一款高性价比双输出隔离型DC-DC转换器，输入电压范围宽（9V～18V），提供对称输出 ±9V，额定输出功率为3W，单路最大输出电流167mA，转换效率典型值可达78%。器件采用SIP-7封装，体积小巧（22×9.5×12 mm），适用于空间受限、需隔离电源的工业与通信类系统。
二、主要电气参数
- 输入电压 Vin：9V ～ 18V
- 输出电压 Vout：±9V（双路）
- 输出功率：3W（总功率）
- 输出电流（单路最大）：167mA
- 最大容性负载：680µF（每路）
- 转换效率：≈78%
- 开关频率：300kHz
- 纹波噪声：100mVp-p（典型）
- 隔离电压 Vrms：1500V
- 工作温度范围：-40℃ ～ +85℃
三、保护与可靠性
WRA1209S-3WR2 集成短路保护、欠压保护与过流保护，能够在异常工况下自动限制输出或进入保护状态，从而增加系统安全性。器件在宽温区间内可靠工作，适合工业环境。隔离电压达到1.5kVrms，可用于需要基本隔离防护的场合。
四、机械与封装
SIP-7 直插封装，外形尺寸 22×9.5×12 mm，便于插件式电路板布局和模块替换。小体积有利于高密度装配，但在散热要求较高的应用中建议预留通风空间或采用散热措施。
五、典型应用场景
- 工业控制与传感器供电（需隔离的模拟或数字回路）
- 通信设备中的偏置电源或辅助电源
- 医疗类非生命维持电路的次级隔离电源（需结合系统认证）
- 单板计算模块、仪器仪表的隔离供电
六、使用建议与注意事项
- 输入侧建议并联合适的去耦电容和滤波器，以抑制输入尖峰并改善EMI性能。
- 输出侧如接大容性负载，注意容性负载上限（680µF），过大容值会影响瞬态响应与稳定性。
- 为保证长期可靠性，高温环境下应用应考虑降额使用或加强散热（自然对流或强制风冷）。
- 布局时保持输入、输出与地线短且宽，输入输出端避免与高速信号线并行，确保隔离间距满足系统安全要求。
- 在对外放电或高压环境下，隔离特性随系统设计和爬电距离而异，涉及安全认证时需结合整机设计做进一步验证。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
