WH251E-3/TR 是 WILLSEMI(韦尔)推出的一款全极型霍尔效应开关,适用于低电压、低功耗的磁感应开关场合。该器件采用小型 TSOT-23-3L 封装,能够在 1.65V 至 5V 的电源电压范围内稳定工作,具有推挽输出,便于直接与 MCU 或数字逻辑接口连接。
WH251E-3/TR 在典型工作条件下以低电流消耗和明确的开关阈值为特点。吸合/释放点间存在设计滞后,能有效抑制噪声与抖动,适合位置检测、限位、计数及速度测量等场景。
该器件为三引脚 TSOT-23-3L 封装,常见引脚功能包括 VCC、GND 与 OUT(推挽输出)。建议在电源引脚旁放置 0.01 μF~0.1 μF 的去耦电容,靠近芯片引脚布置,以保证电源稳定性和抗干扰能力。
WH251E-3/TR 中的 “TR” 表示卷带包装,适合 SMT 自动贴片生产。有关更详细的电气参数、输出电流能力及典型应用电路,请参考厂方完整数据手册或向供应商咨询以获取最新资料。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
