ACS723LLCTR-05AB-T 是美国 ALLEGRO(埃戈罗)推出的一款高精度、低阻抗、双向电流传感器,采用基于霍尔效应的集成芯片设计并封装为 8 引脚 SOIC。该器件在 5V 工作电压下可实现 ±5A 量程的 AC/DC 电流测量,输出为与电源中点偏置的模拟电压,便于后端模拟或 ADC 采集。器件提供 2400Vrms 的隔离能力,适合对高压电路进行安全隔离测量。
器件通过在封装内集成的磁通导向结构和霍尔传感器,在线路电流产生磁场时测量该磁场并转换为与电流成比例的电压信号。输出在无电流时通常偏置于 VCC/2(约 2.5V),正负电流分别使输出上升或下降,输出与电流成线性关系,灵敏度为 400 mV/A。低电流端电阻(0.65 mΩ)保证在大电流通过时的功耗与压降很小,适合需要低插损的场景。
ACS723LLCTR-05AB-T 提供 8-SOIC 表面贴装封装,便于自动化贴片与回流焊工艺。实际使用时建议注意以下要点:
ACS723LLCTR-05AB-T 适合需要精准、低损耗且带有电气隔离的中等电流测量场合。其主要优势在于:高灵敏度(400 mV/A)带来较高的分辨率、极低的导通电阻降低系统功耗、2400Vrms 隔离提升安全性以及宽温度范围适应工业环境。选型时请根据系统带宽、精度要求及环境电磁干扰情况,合理配置滤波与去耦,确保器件在目标应用中发挥稳定可靠的测量性能。

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.
