Viking光颉ARG06DTC1000是一款针对高精度、宽温环境设计的贴片薄膜电阻,型号中“1000”对应100Ω阻值,“ARG06DTC”为光颉旗下通用高精度系列,1206封装适配自动化贴装,广泛覆盖工业控制、消费电子等场景。
ARG06DTC1000的参数围绕“稳定、精准”设计,关键指标清晰支撑应用需求:
电阻类型与精度
采用薄膜电阻工艺(区别于碳膜的低漂移特性),阻值精度达±0.5%——比常规贴片电阻(±1%)高一级,可满足信号调理、分压电路等对阻值一致性的要求;100Ω为常用基准阻值,适配多数电路设计。
功率与电压额定值
额定功率250mW,对应1206封装的常规功率等级;工作电压200V需注意功率-电压匹配:实际使用中,若电压超过141V(√(0.25W×100Ω)),需优先按功率限制电流(最大允许电流50mA),避免过载损坏。
温度特性
温度系数(TCR)±25ppm/℃,表示温度每变化1℃,阻值变化仅百万分之25;结合-55℃~+155℃的宽工作温区,即使在极端环境下(如工业高温车间、低温户外设备),阻值漂移仍可控在0.3%以内(155℃相对25℃的温差130℃,漂移量130×25ppm=0.325%)。
封装与贴装
1206英制封装(对应公制3216),尺寸小巧(3.2mm×1.6mm),适配主流SMT贴装设备,焊接兼容性好(回流焊峰值温度≤260℃符合行业标准)。
ARG06DTC1000的参数特性使其适配以下场景:
工业控制电路
宽温范围(-55~155℃)和高精度(±0.5%)适合PLC输入输出模块、传感器信号放大电路——例如压力传感器的分压校准,需稳定阻值保证信号精度;同时250mW功率可满足中等电流负载需求。
消费电子终端
1206封装的高贴装效率适合手机、平板的电源管理电路(如电池电压分压检测),±0.5%精度可减少电压检测误差;薄膜电阻的低噪声特性也适合音频电路的信号衰减。
汽车辅助电子
温区覆盖汽车级常规工作范围(-40~125℃),可用于车载仪表盘背光调节、辅助传感器(如胎压监测模块)的信号处理,需注意部分汽车级场景需额外认证,但参数已满足基础可靠性要求。
通信设备
信号链路的阻抗匹配(如射频前端的50Ω匹配衍生设计),薄膜电阻的低寄生电感/电容特性(1206封装寄生参数约nH级)不影响高频信号传输。
光颉(Viking)作为台湾老牌电阻厂商,ARG系列经过严格可靠性测试:
这款电阻以“高精度+宽温稳定+易贴装”为核心优势,是中高端电子设计中替代常规电阻的高性价比选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
