Viking(光颉)ARG02FTC5102是一款针对高密度、高可靠性电路设计的精密薄膜贴片电阻,采用0402(1005公制)小型化封装,核心参数覆盖51kΩ±1%阻值精度、62.5mW额定功率、±25ppm/℃温度系数及-55℃~+155℃宽温工作范围,广泛适配消费电子、工业控制、汽车电子等多领域应用场景。
ARG02FTC5102属于光颉ARG系列精密薄膜电阻,区别于普通厚膜电阻的丝网印刷工艺,采用真空溅射+光刻的薄膜制造技术,核心定位为:
标称阻值51kΩ,精度等级±1%,属于行业通用精密电阻范畴。实际应用中,该精度可避免模拟电路(如传感器信号放大、电压基准分压)因电阻误差导致的输出偏差——例如在12V基准分压电路中,±1%精度可将输出电压偏差控制在±120mV以内,满足大多数工业测量场景的校准需求。
±25ppm/℃是薄膜电阻的核心优势(厚膜电阻TC通常≥±100ppm/℃)。以温度变化100℃为例,阻值漂移量仅为(51kΩ×25ppm/℃×100℃=127.5Ω),相对漂移率0.25%,可有效降低宽温场景(如汽车发动机舱、工业现场)下的电路性能波动。
采用0402英制封装(尺寸2.0mm×1.0mm),是贴片电阻中尺寸极小的规格之一,可显著提升PCB集成密度——例如在智能手机射频前端,0402封装可减少30%以上的布局空间,适配5G终端的小型化需求。
通过真空溅射制备均匀电阻膜层(厚度10-100nm),相比厚膜工艺:
配置三层端电极结构(镍底层+铜中间层+锡表层):
支持-55℃~+155℃,覆盖:
通过振动(10-2000Hz,加速度2g)与冲击(1000g,6ms)测试,可承受便携式设备的跌落、振动场景(如智能手表的日常使用)。
ARG02FTC5102作为精密薄膜电阻的优选方案,核心价值在于:
该产品可替代普通厚膜电阻,尤其适合对精度、稳定性、空间有严格要求的电路设计场景,是工业级与消费电子领域的高性价比选择。

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.
