AR03FTCX3R30是台湾Viking(光颉)公司推出的0603封装精密薄膜贴片电阻,针对小型化、高稳定性电子设备设计,具备精准阻值控制、宽温域可靠运行等核心特性,广泛适配消费电子、工业控制、智能穿戴等多领域场景。
该型号采用镍铬薄膜工艺制造,通过激光微调实现高精度阻值控制,核心参数如下:
±1%的精度等级结合±25ppm/℃的TCR,使得电阻在**-55℃至155℃**的宽温域内,阻值漂移量仅为:
3.3Ω×25ppm/℃×210℃≈±0.0173Ω
远低于碳膜电阻的漂移水平,适合传感器接口、医疗设备信号调理等对长期稳定要求高的场景。
100mW额定功率适配低功耗电路,而75V直流额定电压则突破常规0603电阻(多为50V以下)的限制,可满足:
-55℃+155℃的工作温度范围,超越消费级电阻(0℃70℃),可适应:
镍铬薄膜电阻相比碳膜、金属氧化膜电阻,具备:
0603封装(英制0603,公制1608)体积仅1.6mm×0.8mm,厚度约0.45mm,可显著缩小电路尺寸,适配:
Viking(光颉)作为全球被动元件制造商,AR03FTCX3R30符合:
综上,AR03FTCX3R30凭借精密阻值、宽温稳定、小体积等特点,成为小型化电子设备中低功率精密电阻的优选方案,适配多场景的可靠性需求。

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.
