ARG02BTC1102是Viking(光颉)推出的高精度薄膜贴片电阻,针对对阻值精度、温度稳定性要求严苛的小功率电路场景设计,核心特性可总结为:
标称阻值11kΩ为标准常用阻值,适配绝大多数模拟电路、信号调理电路的电阻匹配需求;±0.1%的精度意味着在25℃基准温度下,实际阻值偏差不超过11Ω(11kΩ×0.1%),可有效降低电路系统的误差累积,适合对信号精度敏感的场景(如精密仪表、传感器放大电路)。
±25ppm/℃的温度系数表示:当温度每变化1℃时,阻值变化量为11kΩ×25×10⁻⁶=0.275Ω;若温度变化100℃(如从-55℃到+45℃),阻值总变化仅27.5Ω,占标称值的0.25%,远低于普通电阻的温漂水平,确保电路在宽温环境下性能稳定。
额定功率62.5mW是0402封装薄膜电阻的典型功率等级,可满足小电流(I≈√(62.5mW/11kΩ)≈2.39mA)电路的功率承载需求;50V的工作电压则为电路提供安全裕量,避免瞬时过压导致电阻击穿失效。
-55℃+155℃的宽温范围覆盖工业级环境(通常-40℃+85℃)及部分汽车电子的极端温度需求,可在户外设备、车载系统等严苛场景下长期稳定工作。
0402封装尺寸(约1.0mm×0.5mm)体积小巧,适合高密度PCB设计(如智能手机、可穿戴设备、小型工业模块),可有效节省电路板空间,提升集成度。
采用真空溅射薄膜工艺制备电阻层,相比碳膜、金属膜电阻具有:
产品符合贴片电阻通用可靠性标准,支持回流焊、波峰焊等常规贴片工艺,无铅封装适配RoHS要求;宽温设计及薄膜工艺确保长期使用中阻值变化极小,可满足工业设备5~10年的使用寿命需求。
ARG02BTC1102的参数特性使其适用于以下场景:
Viking(光颉)是全球知名被动元件制造商,专注电阻、电感研发生产,拥有成熟薄膜工艺及严格质量管控:
总结:ARG02BTC1102是一款专为高精度、宽温、小功率场景设计的薄膜贴片电阻,凭借±0.1%高精准度、±25ppm/℃低温漂及0402小封装,成为精密仪器、工业控制、汽车电子等领域的理想选择。
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.
