ACS714LLCTR-30A-T 为美国 ALLEGRO(埃戈罗)推出的一款开环(Open‑Loop)霍尔电流传感器,适用于 AC/DC 双向电流测量。器件工作电源为 5V,封装为 8‑引脚 SOIC(0.154" / 3.90 mm 宽),以卷带(T/R)形式供货。型号中的 “30A” 表示器件针对最大直流/交流电流量程设计,可在正负方向检测电流极性。
ACS714 系列采用霍尔效应检测导体产生的磁场,输出为与流经导体的电流成比例的模拟电压,零电流时输出约为 VCC/2。输出可直接驱动 ADC 采样,便于在 MCU/ARM 系统中进行数模处理与计算。作为开环器件,其线性与精度在多数工业与消费类应用下表现良好,但在极端精度需求下需借助校准或闭环方案。
总结:ACS714LLCTR‑30A‑T 为一款适用于广泛工业与消费类电流监测的开环霍尔传感器,集成度高、易于 PCB 安装和系统集成。通过合理的电源滤波、PCB 布局与校准设计,可在±30A 范围内提供可靠的双向 AC/DC 电流测量解决方案。若需更高精度或特殊温度/带宽指标,请结合详细数据手册与样片验证。

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.
