B2412S-1WR3 产品概述

一、产品简介

B2412S-1WR3 是 YLPTEC(易川) 推出的高效率、隔离型降压型开关电源模块。模块输入适配 24V 工况(工作电压 21.6V~26.4V),单路输出 12V,输出功率约 1W,封装为经济型 SIP-4,体积小巧(11.6 × 6 × 10.16 mm),适合对体积、效率和隔离性能有要求的嵌入式及工业应用。

二、主要技术参数

  • 功能类型:降压型(Buck)
  • 通道数:1 路
  • 输入电压:21.6 V ~ 26.4 V
  • 输出电压:12 V
  • 输出电流(最大):84 mA
  • 输出功率:1 W
  • 峰值效率:约 91%
  • 最大容性负载:560 μF
  • 隔离电压(Vrms):1.5 kV
  • 开关频率:260 kHz
  • 工作温度:-40 ℃ ~ +105 ℃
  • 保护特性:短路保护
  • 封装:SIP-4,尺寸 11.6 × 6 × 10.16 mm

三、性能亮点

  • 高效率:最高可达 91%,在 1W 额定输出时,转换损耗小(典型损耗约 0.1W),有利于减少发热并延长寿命。
  • 强隔离:1.5 kVrms 隔离等级,适合需要隔离保护的信号与电源分界场合。
  • 小体积:SIP-4 紧凑封装,便于 PCB 密集布局和模块化设计。
  • 容性适应性强:支持最大 560 μF 输出容性负载,利于驱动较大电容滤波或后级缓冲。
  • 保护功能:具备短路保护,提高系统抗故障能力。

四、典型应用场景

  • 工业控制器供电隔离
  • 信号隔离与传感器供电
  • 通信设备低功率电源
  • 仪器仪表与数据采集模块
  • 自动化系统中小功率隔离电源

五、设计与使用建议

  • 输入/输出滤波:建议在输入侧配置低 ESR 去耦电容(例如 10 μF 附近)以抑制输入纹波;输出侧可按系统需求使用高质量电解或固态电容,注意单颗电容不超过模块允许的最大容性负载(560 μF)。
  • 布局要点:模块靠近输入源放置,最短并粗的输入/输出连线可降低 EMI 与压降;为实现良好隔离,保持模块隔离边缘的爬电距离和杂散电容最小化。
  • 散热与功耗:在额定负载下模块效率高,功耗约 0.09–0.12W,常温下无需外加散热片;在高温或受限通风环境,应评估结温并适当降载或改善散热。
  • 干扰抑制:开关频率为 260 kHz,若对 EMI 敏感,应在输入/输出端加 LC 滤波及共模电感,并注意 PCB 接地处理。
  • 保护与可靠性:尽管模块内置短路保护,外部仍建议加入保险丝或浪涌抑制器,以提高系统整体安全性。

六、包装与选型提示

  • 封装:SIP-4,便于插装或波峰/手工焊接。
  • 选型时注意输入工作电压裕量、所需隔离等级及输出容性负载能力;若工作环境温度常处高温或需要更高输出电流,应考虑更大功率等级的模块。

B2412S-1WR3 以其高效率、强隔离和小体积特点,适合多类需要稳健隔离供电的嵌入式与工业场景。选择与设计时按照上文建议进行输入输出滤波、合理布线与热管理,可获得稳定可靠的长期工作表现。若需参考典型应用电路或更详细的电气特性曲线,可联系供应商获取完整数据手册与评估样片。

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
