AR03BTCX4022是Viking(光颉)薄膜电阻系列中的高精度宽温型小型化贴片电阻,核心定位为**“小体积下的高性能平衡”**——针对对阻值精度、温度稳定性要求严苛,同时需紧凑封装的电路设计场景,解决传统厚膜电阻精度不足、宽温漂移大,或大封装电阻无法适配高密度PCB的痛点,适用于医疗、工业、通信等多领域的精密电子设备。
该电阻的核心参数围绕“高精度、宽温稳定、小型化”设计,具体如下:
标称阻值40.2kΩ,精度±0.1%——远高于普通厚膜电阻(±1%~±5%),可满足医疗监护仪、精密仪器的信号调理、基准电压电路等对阻值一致性的要求,减少产品校准环节的成本与复杂度。
额定功率100mW,适配0603封装(1.60mm×0.80mm×0.45mm)——在小型化封装下实现100mW功率输出,避免因功率不足导致的热漂移或失效,适合通信模块、便携式设备的高密度布局。
±25ppm/℃——表示温度每变化1℃,阻值变化±25×10⁻⁶,即100℃变化下阻值漂移仅±0.25%,远优于厚膜电阻(通常±100ppm/℃以上),能稳定工作在**-55℃~+155℃宽温区**,适配工业现场、汽车电子等极端环境。
-55℃~+155℃——覆盖工业级、汽车级温区要求,无需额外降额或散热设计,降低电路复杂度与BOM成本。
Viking采用Ni-Cr合金薄膜工艺(比传统碳膜、厚膜更稳定):
该电阻通过多项行业标准测试,可靠性符合严苛要求:
实际使用功率建议不超过额定功率的80%(即80mW),避免热过载导致阻值漂移或失效;若电路功率需求超过100mW,需选择更大封装(如0805)的同阻值电阻。
若工作环境温度超过+155℃(如航空航天特殊场景),需选择更高温区的电阻型号;若对温度系数要求更高(如±10ppm/℃),可考虑Viking同系列高精度型号。
AR03BTCX4022通过薄膜工艺、0603封装与宽温高精度参数的结合,成为精密电子设备中**“小型化”与“高性能”平衡的优选元件**,适配多行业的严苛应用需求,是医疗、工业、通信等领域提升产品精度与可靠性的可靠选择。

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.
