FC-SCT2108-100T 电流互感器产品概述

FC-SCT2108-100T是方成(FC)品牌推出的贴片式高精度电流互感器,专为工业自动化、电力监控、新能源等领域的大电流检测需求设计,核心围绕「高隔离、低损耗、易集成」三大特性,适配多种高压/低压电路的电流信号转换与监测场景。

一、核心参数及性能指标

该产品的关键参数直接决定应用边界与性能表现,具体如下:

  • 匝数比:1:100(初级输入电流与次级输出电流的线性比例,初级50A时次级输出0.5A);
  • 额定输入电流:50A(连续工作最大允许电流,短时间过载需参考规格书);
  • 隔离电压:5kV Vrms(满足高电压隔离要求,有效隔离高压侧与低压控制电路);
  • 次级侧电感:4.5mH(保证信号线性传输,减少高频噪声干扰);
  • 内阻特性:初级侧最大0.5mΩ(极低损耗),次级侧最大2.6Ω(匹配后续信号处理电路);
  • 封装规格:SMD-6P(6引脚贴片封装),尺寸20.5×12.8mm(紧凑适配高密度PCB)。

二、封装与物理特性

采用SMD-6P贴片封装,具备三大物理优势:

  1. 自动化生产适配:支持回流焊/波峰焊批量焊接,无需手工插件,提升生产效率;
  2. 空间利用率高:20.5×12.8mm紧凑尺寸(不含引脚高度),适配小型化设备(如充电桩控制板、光伏逆变器模块);
  3. 引脚布局清晰:标准化间距设计,焊接不易短路,方便与运放、ADC等电路直接连接,简化设计流程。

三、关键技术优势

相较于同类型产品,核心竞争力体现在:

  • 高隔离安全保障:5kV Vrms隔离电压满足IEC 61010安规标准,可直接应用于光伏逆变器、高压配电系统,隔离高压与低压回路,避免安全隐患;
  • 低损耗高精度:初级0.5mΩ内阻,50A额定电流下自身损耗仅1.25W(I²R计算),远低于传统插件互感器,减少发热对精度的影响;
  • 线性度优异:1:100严格线性比例,配合4.5mH次级电感,0.1A~50A范围内电流转换误差控制在±1%以内(参考规格书);
  • 宽温适应性:工业级温度范围(-40℃~+85℃,以官方规格书为准),满足户外充电桩、工业现场等极端环境需求。

四、典型应用领域

参数特性使其广泛适配以下场景:

  1. 新能源:光伏逆变器并网电流监测、充电桩充电电流检测、储能系统电池组电流监控;
  2. 工业自动化:变频器驱动电机过载保护、PLC设备电流监测、工业机器人关节电流控制;
  3. 电力监控:低压配电盘出线电流测量、智能电表高精度采集、UPS负载电流监控;
  4. 消费电子:高端电源适配器电流保护、智能家电(空调/热水器)负载监测。

五、选型与使用注意事项

为保证性能与安全,需注意:

  1. 额定电流限制:连续工作不超50A,短时间过载控制在2倍额定电流以内(参考过载曲线);
  2. 次级负载匹配:建议负载电阻10~100Ω,避免过小导致电感饱和;
  3. 焊接工艺:回流焊峰值温度≤260℃、时间≤10s,防止高温损坏磁芯;
  4. 隔离距离:PCB布线初级/次级间距≥2mm,满足5kV爬电距离要求;
  5. 环境防护:户外/潮湿环境需加PCB涂层(如 conformal coating),避免水汽影响绝缘。

总结

FC-SCT2108-100T作为方成主流贴片互感器,以高隔离、低损耗、易集成为核心优势,精准匹配多领域大电流检测需求。紧凑封装与优异线性度简化系统设计、提升生产效率,同时保障高压场景安全可靠性,是中高端电流监测系统的理想选型。

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
