一、产品简介

B1212S-2WR3 是 YLPTEC(易川)出品的一款单通道隔离型 DC-DC 转换器,额定输出功率 2W,输入标称 12V(工作电压范围 10.8V~13.2V),输出 12V,最大输出电流 166mA。模块为插件封装,外形尺寸小巧(19.5 × 7 × 10 mm),适合对体积、隔离和低功耗有要求的嵌入式与工业应用。描述:校验通过!

二、主要参数

  • 通道数:1
  • 输入电压:10.8V ~ 13.2V(标称 12V)
  • 输出电压:12V
  • 输出功率:2W
  • 最大输出电流:166mA
  • 转换效率:86%(典型)
  • 最大容性负载:560µF
  • 隔离耐压(Vrms):1.5kV
  • 开关频率:100kHz
  • 保护功能:短路保护
  • 工作温度:-40℃ ~ +85℃
  • 封装:插件(Through-hole)
  • 外形尺寸:19.5 mm × 7 mm × 10 mm

三、性能亮点

  • 高效率:典型效率 86%,在满载时输入功率约为 2W/0.86 ≈ 2.33W,功耗约 0.33W,便于热管理。
  • 隔离性能:1.5kV RMS 隔离,适用于信号隔离、地回路消除及测量系统。
  • 稳定驱动大电容负载:最大容性负载可达 560µF,适合驱动具有滤波或储能电容的负载。
  • 小型化插件封装,便于 PCB 插装与更换维护。
  • 宽温区和短路保护,满足苛刻工业环境下的稳定运行要求。

四、典型应用

  • 工业控制与 PLC 信号隔离
  • 仪表与传感器前端隔离供电
  • 通信设备、基站外围模块
  • 电池系统与车载辅助电源(注意输入电压范围匹配)
  • 地环路隔离、模拟/数字接口隔离

五、使用与设计建议

  • 输入端应并联适当去耦电容以抑制干扰,推荐使用低 ESR 电解或钽电容配合陶瓷电容。
  • 输出端若并联大电容,确保不超过最大容性负载 560µF,以免影响稳定性与瞬态响应。
  • 由于具备短路保护,设计时仍应避免长期短路工作;若需更严苛保护,建议外部限流或保险丝配合。
  • 布局时保证输入、输出与模块隔离区的爬电距离,保持良好接地与散热路径。
  • 对于高 EMI 环境,可在输入端加入 LC 滤波器以降低开关噪声泄露。

六、热管理与可靠性

在满载且效率为 86% 的情况下,模块自身功耗约 0.3–0.4W,通常无需额外散热片,但在高温或密集封装场景下建议预留空气对流空间或在 PCB 上做散热过孔。工作温度范围 -40℃~+85℃,适合大多数工业级应用。长期可靠性与寿命会受环境温湿度、输入纹波与过压冲击影响,建议在设计阶段做好滤波与保护电路。

七、选型与采购注意

  • 确认系统输入电压稳定在 10.8V~13.2V 范围;若存在更宽范围的电源,应选择相应输入等级的模块或加入前级稳压。
  • 若需更高隔离等级或更大输出功率,请咨询厂商更高规格产品。
  • 订单与样片可通过 YLPTEC(易川)代理或官方渠道获取,订购时注明型号 B1212S-2WR3 与插件封装要求。

总结:B1212S-2WR3 是一款体积小、效率高、具隔离与短路保护的 2W 单路 DC-DC 模块,适合用于要求隔离、低功耗及稳定供电的小型嵌入式和工业系统。

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
