Viking光颉ARG06DTC4703是一款1206封装高精度薄膜贴片电阻,专为工业级、通信及医疗电子等对阻值稳定性要求严苛的场景设计。其核心优势围绕「高精度、宽温适配、小功率精密」展开:
ARG06DTC4703的电气参数经过严格校准,关键指标可支撑稳定电路设计:
标称阻值为470kΩ(470×10³Ω),精度±0.5%,标准温度(25℃)下实际阻值范围为467.65kΩ~472.35kΩ(误差±2.35kΩ)。该精度可满足信号调理、分压电路等对阻值一致性要求较高的场景。
温度系数(TCR)±25ppm/℃,即温度每变化1℃,阻值变化±25×10⁻⁶倍。例如:环境温度从25℃升至125℃(变化100℃),阻值变化仅±0.25%,远优于普通电阻的±100ppm/℃以上水平,确保宽温区下电路性能稳定。
支持-55℃至+155℃工业级温区,可适应低温户外设备、高温汽车发动机舱等极端环境。
ARG06DTC4703采用1206贴片封装(英制0.12″×0.06″,公制3.2mm×1.6mm),兼具贴装效率与可靠性:
适配常规SMT贴片机,吸嘴规格匹配1206封装,适合大规模自动化生产,降低人工成本。
采用镍铬合金薄膜沉积技术,相比碳膜、金属氧化膜电阻:
产品通过以下严苛测试:
ARG06DTC4703的性能特点使其广泛适用于以下场景:
为确保稳定工作,需注意以下要点:
实际功耗需满足:P实际 ≤ 175mW;
工作电压需满足:U实际 ≤ 200V(同时验证P实际=U实际²/R ≤175mW)。
确认应用环境温度在-55℃~+155℃范围内,超出需更换耐温更高的型号(如175℃高温场景)。
ARG06DTC4703以高性价比实现了工业级精度与稳定性,是精密电子电路的可靠选择。

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.
