B2412S-3WR2 产品概述

一、产品概述

B2412S-3WR2 是 YLPTEC(易川)推出的一款小功率隔离型 DC-DC 转换器,专为分布式电源系统中需要产生一路与输入电源电气隔离的应用场景设计。模块采用 SIP-4 封装,体积小巧,效率高,能在受限空间内为纯数字电路、低频模拟电路、继电器驱动和数据交换电路等提供稳定的隔离 12V 电源输出。

二、主要规格

  • 输入电压(Vin):21.6V ~ 26.4V(典型 24V 总线)
  • 输出功率:3W
  • 输出电压(Vout):12V
  • 输出电流(最大):250mA
  • 最高转换效率:约 88%
  • 隔离电压(Vrms):1500V
  • 最大容性负载:560μF
  • 纹波噪声:80mVp-p(典型)
  • 开关频率:250kHz
  • 无负载输入电流:低至 4mA(系列典型值)
  • 工作温度:-40℃ ~ +85℃
  • 外形尺寸(L×W×H):19.65mm × 10.16mm × 7mm
  • 封装:SIP-4

注:系列中也提供其它输出规格(例如 15V/200mA 等),可根据应用与客户需求选型或定制。

三、功能与保护特性

  • 短路保护:内置短路保护机制,可在异常时刻限制输出并防止器件损坏。
  • 自动故障恢复:当故障消除后,模块能自动恢复正常工作,无需人工复位。
  • 低空载电流:提高系统待机能效,适合需长时间待机或低功耗运行的场景。
  • 低纹波、低噪声输出:满足对电源质量有一定要求的信号处理与通信类电路。

四、应用场景

  • 分布式电源或子模块供电:为局部电路提供隔离电源,提升系统安全与抗干扰能力。
  • 纯数字电路、MCU 与接口模块供电:稳定的 12V 来源,可驱动部分外围器件或继电器。
  • 低频模拟电路与测量仪表(对噪声敏感度有限的场景)。
  • 数据交换、通信接口及继电器驱动等需要隔离与小功率输出的场合。

五、设计与选型建议

  • 输入电压裕量:确保工作时输入稳定在 21.6–26.4V 范围内,避免高纹波或冲击电压超出范围。
  • 散热与环境:在高温或近额定功率工作下,注意改善散热或降载使用以延长寿命;工作温度范围内使用需考虑功率随温度的降额曲线。
  • 容性负载能力:模块支持最高约 560μF 的容性负载,但建议按实际启动与稳定时间评估,以免启动冲击影响稳定输出。
  • 隔离与安全:1500V 隔离适用于一般信号隔离与小电流隔离场合;如需更高耐压或医疗级隔离,请与供应商确认或选型更高等级产品。
  • 定制需求:若有不同输出、电压配比或更严苛环境适配需求,YLPTEC 提供系列产品或按客户要求定制特殊规格。

六、总结

B2412S-3WR2 以其小体积、较高效率(约 85–88%)、1500V 隔离能力及短路自动恢复特性,适合用于对电气隔离、稳定性和空间占用有严格要求的分布式电源与控制系统。选择时应结合实际工作电压、负载特性与散热条件,确保在推荐工况下长期稳定运行。若需详细电气特性曲线、效率图或认证资料,可联系供应商获取完整数据手册。

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
