WRA2415S-3WR2 产品概述

一、产品简介

WRA2415S-3WR2 是 YLPTEC(易川) 推出的双通道降压型隔离 DC-DC 模块,采用 SIP-7 封装,专为需要对称 ±15V 小功率电源的工业和嵌入式应用而设计。模块通过校验,具有稳定的电气性能与过短路保护功能,适合仪表、信号隔离、逻辑驱动及小功率放大器等场合。

二、主要技术参数

  • 功能类型:降压型
  • 输入电压 Vin:18V ~ 36V
  • 输出电压 Vout:±15V(双通道)
  • 输出电流(最大):±100mA(每个通道)
  • 输出功率:3W(总功率)
  • 转换效率:典型 80%
  • 隔离电压 Vrms:1.5kV
  • 最大容性负载:220µF
  • 纹波噪声:100mVp-p(典型)
  • 开关频率:300kHz
  • 封装:SIP-7,外形尺寸 22mm × 9.5mm × 12mm(长×宽×高)
  • 工作温度:-40℃ ~ +85℃
  • 特性:短路保护
  • 品牌:YLPTEC(易川)
  • 描述:校验通过!

三、核心特性与优势

  • 双向对称输出:±15V 输出提供对称电源,便于驱动差分放大器或双极性信号链,减少外部电路设计复杂度。
  • 高度隔离:1.5kV RMS 隔离保证输入与输出侧的安全隔离,适合测量与通信接口隔离应用。
  • 紧凑封装:SIP-7 小体积设计(22×9.5×12mm),便于在空间受限板上布局。
  • 宽输入范围:18~36V 输入兼容多种电源总线(如 24V/28V 系统),提高系统适配性。
  • 可靠保护:具备短路保护,提升系统可靠性和抗故障能力。
  • 良好抗容性负载:支持最高 220µF 容性负载,适合驱动含滤波或储能电容的负载。

四、典型应用场景

  • 工业控制与现场总线接口(需要隔离的传感器供电)
  • 仪器仪表中的放大器和模拟前端电源
  • 通信设备与接口电源隔离
  • 数据采集、模数转换前端的对称电源供给
  • 铁路、电力等需要高可靠性与高隔离等级的环境

五、设计与使用建议

  • 输入侧应并联合适的去耦电容,以降低输入纹波并提高稳定性;输出端建议并联低等效串联电阻(ESR)的电解或钽电容,但总容性负载不超过 220µF。
  • 布局时保持模块的输入、输出地尽量短且分开处理,保证隔离性能与抗干扰能力。
  • 在高温或高负载工况下注意散热,尽量保证模块周围空气流通以维持效率与寿命。
  • 若系统对纹波噪声敏感,可在输出端增加LC或RC滤波以进一步降低噪声至所需水平。

六、可靠性与合规

模块工作温度范围宽(-40℃~+85℃),适合严苛环境使用;短路保护机制有助于防止外部故障对模块和系统的损害。建议在最终产品设计中结合系统级安全与 EMC 设计规范,完成相应的认证与可靠性验证。

总结:WRA2415S-3WR2 以其对称 ±15V 输出、高隔离等级、小尺寸封装与短路保护等特点,为需要隔离小功率对称电源的场景提供了可靠且易于集成的解决方案。若需样片或详细应用资料,可联系 YLPTEC(易川) 获取完整数据手册与推荐电路。

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.

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
