AR06FTD4993 薄膜贴片电阻产品概述

AR06FTD4993是光颉(Viking)推出的1206封装精密薄膜贴片电阻,针对中高精度电路设计,兼顾稳定性与环境适应性,广泛适用于工业控制、消费电子、汽车辅助系统等场景。

一、产品核心定位

该电阻属于光颉薄膜电阻系列中的常规精密型号,以**±1%阻值精度**、低温度漂移为核心优势,解决普通电阻(如碳膜)在宽温、精密电路中阻值不稳定的问题;同时1206封装平衡了功率容量与PCB布局空间,适合中小信号电路的标准化设计,无需特殊定制即可满足多数常规精密场景需求。

二、关键电气参数详解

1. 阻值与精度

标称阻值为499kΩ,精度等级±1%——实际阻值范围在494.01kΩ503.99kΩ之间,可满足电源反馈分压、传感器信号调理等对阻值误差敏感的电路(例如05V信号的精准分压,整体误差可控制在0.5%以内)。

2. 功率与电压规格

  • 功率容量:125mW(0.125W):适配1206封装的常规功率需求,可稳定承载中小电流信号(如1mA电流下,功耗仅0.499mW,远低于额定值,长期运行无过热风险);
  • 工作电压:150V(直流/交流峰值):绝缘耐压满足多数低压电路的过压防护要求,避免因电压冲击导致击穿,适配常规电源、信号传输电路。

3. 温度特性与环境适应

  • 温度系数(TCR):±50ppm/℃:温度每变化1℃,阻值漂移不超过百万分之五十(即0.005%/℃)。在全温区(-55℃~+155℃)变化中,最大阻值漂移约1.05%,远优于普通碳膜电阻(通常TCR±200ppm/℃以上),确保极端温度下电路性能稳定;
  • 工作温度范围:-55℃~+155℃:覆盖工业级环境(如户外设备、高温车间)及部分汽车电子场景(如发动机舱周边辅助电路),满足长期可靠运行要求。

4. 封装与物理特性

采用1206封装(英制:0.12英寸×0.06英寸,公制:3.2mm×1.6mm),符合IPC标准:

  • 焊盘设计兼容回流焊、波峰焊,焊接可靠性高,不良率低;
  • 尺寸紧凑,可在高密度PCB上实现多路并联/串联设计,不占用过多布局空间。

三、典型应用场景

  1. 消费电子电源电路:如手机/平板的充电管理模块,用于电压反馈分压,精准控制输出电压(避免过充/欠充);
  2. 工业传感器信号调理:如PT100温度传感器的放大电路,低漂移阻值保证信号采集精度(误差≤0.1℃);
  3. 汽车辅助系统:如仪表盘背光控制、车门传感器电路,宽温特性适配车载环境的温度变化(-40℃~+85℃常规场景全覆盖);
  4. 通信设备滤波网络:如路由器的信号滤波电路,稳定阻值避免信号失真,提升传输质量。

四、品牌与品质保障

光颉(Viking)作为专业电阻制造商,AR06FTD4993采用薄膜沉积+激光微调工艺,确保阻值精度与批量一致性;产品符合RoHS 2.0、无卤标准,环保合规;同时通过振动(10G)、冲击(50G)测试,满足工业级可靠性要求,可长期稳定运行于严苛场景。

该产品以高性价比、稳定性能成为中高精度电路的常规选择,适配多数标准化设计需求。

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
