B2412S-2WR3 产品概述

一、产品简介

B2412S-2WR3 是 YLPTEC(易川) 推出的高可靠性隔离型降压直流-直流模块,单通道、额定输出功率 2W,专为工业与通信电源、嵌入式系统和测试仪器等场景设计。模块采用插件封装,体积小巧(19.5 × 7 × 10 mm),在 21.6V~26.4V 输入范围内稳定输出 12V,具有短路保护与低功耗特性,并通过校验验证,适合要求隔离与稳定供电的应用。

二、主要电气参数

  • 功能类型:降压型(Buck)
  • 通道数:1
  • 输入电压 Vin:21.6V ~ 26.4V
  • 输出电压 Vout:12V(固定)
  • 输出电流(最大):166mA
  • 输出功率:2W
  • 转换效率:典型 89%(视负载与输入电压略有变化)
  • 最大容性负载:560 μF
  • 隔离电压 Vrms:1500 V
  • 开关频率:100 kHz
  • 保护功能:短路保护
  • 工作温度范围:-40 ℃ ~ +85 ℃

为了估算输入电流:在满载且效率 89% 时,输入功率约为 2W/0.89 ≈ 2.25W,于 24V 输入下输入电流约 94 mA,便于系统配电与保险选择。

三、主要特性与优势

  • 高效率:约 89% 的转换效率,有利于降低系统发热和延长续航(适配电池或有限电源场合)。
  • 良好隔离:1500 Vrms 隔离能力,满足常见的安全与地回路隔离需求。
  • 可靠保护:内置短路保护,能在异常工况下提供一定程度的安全保障。
  • 低功耗设计:轻载或空载时功耗低,适合待机与节能场景。
  • 紧凑封装:插件形式便于手工焊接与后期维修、测试。

四、封装与机械尺寸

  • 封装形式:插件(Through-hole)
  • 外形尺寸:长 19.5 mm × 宽 7 mm × 高 10 mm
    体积极小,便于在空间受限的电路板或模块化电源方案中布局。

五、应用场景

  • 工业自动化控制器与传感器供电
  • 通信设备与中继模块的辅助电源
  • 仪器仪表、测试设备的隔离电源
  • 嵌入式系统与单板计算平台的降压供电

六、设计与使用建议

  • 输入/输出旁路电容:尽管模块内部已包含必要滤波,建议在输入端并联适当低 ESR 电容以抑制瞬态;输出侧应注意最大容性负载 560 μF,不宜超标以免影响稳定性。
  • 散热与布局:模块效率较高但仍会产生热量,建议保证良好通风、避免与高热器件紧邻;在高环境温度下适当降额使用以延长寿命。
  • 短路处理:模块具备短路保护,但在系统设计时仍应考虑保险或限流措施以提高整体安全性。
  • EMC 与接地:为获得更好抗干扰性能,输入端建议靠近模块添加铁芯共模电感与滤波器,确保信号地与功率地合理分隔与回流。

七、采购与认证

  • 品牌:YLPTEC(易川)
  • 校验:校验通过,出厂前经过必要电气性能测试。
  • 适用于需要隔离、体积小且效率高的降压场合。如需样品或批量采购,请联系供应商提供更详细的测试报告与库存信息。

如需更详细的电气等效图、启动/关闭特性曲线或在特定环境(如低温高湿、振动)下的可靠性数据,可提供进一步技术支持与样品测试建议。

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
