ARG05FTC4021是Viking(光颉)推出的一款0805封装薄膜贴片电阻,专为对阻值精度、温度稳定性及宽温适应性有要求的电子电路设计,核心参数覆盖工业级及部分高温应用场景,以下从多维度展开概述。
ARG05FTC4021的关键性能参数明确适配中高精度、宽温域的应用需求,具体包括:
0805封装是ARG05FTC4021的核心物理特征,具备以下优势:
ARG05FTC4021的电气性能针对精准信号控制及宽温稳定性优化:
±1%的精度覆盖了工业控制、通信设备等场景的基本需求,且薄膜工艺保证批量生产中阻值一致性优于厚膜电阻,减少电路调试复杂度;
额定功率125mW为25℃环境下的最大值,实际使用需遵循降额曲线:例如在155℃高温下,额定功率需降额至约70%(即87.5mW),避免因功率过载导致阻值漂移或失效;最大工作电压150V为开路电压限制,需确保电路中电压不超过该值;
±25ppm/℃的TCR是其核心优势之一,远优于普通碳膜电阻(通常±500ppm/℃以上),即使在-55℃至+155℃的宽温变化中,阻值漂移量仍控制在可接受范围,适合对温度敏感的电路(如传感器信号调理)。
ARG05FTC4021的参数特性使其适配多类电子领域:
Viking(光颉)作为专业电阻制造商,ARG05FTC4021具备以下可靠性保障:
为确保ARG05FTC4021的性能及寿命,需注意以下事项:
ARG05FTC4021凭借0805封装的紧凑性、薄膜电阻的稳定性及宽温适应性,成为工业、通信、汽车电子等领域中高精度小功率电阻的优选方案之一。
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.
