AR05BTCW1003是Viking(光颉)品牌推出的0805封装精密薄膜贴片电阻,属于该品牌薄膜电阻系列的核心型号。产品采用真空溅射薄膜工艺制造,区别于厚膜电阻的网印工艺,具备更高精度、更低温度系数及长期稳定性,是对阻值一致性要求严苛场景的首选元件。型号中“1003”为阻值编码,对应标称阻值100kΩ(100×10³Ω),明确了核心阻值规格。
标称阻值为100kΩ,精度等级达**±0.1%**,属于精密级电阻范畴。薄膜工艺通过均匀沉积电阻膜并精准刻蚀,使阻值偏差控制在极小范围,相比厚膜电阻(典型精度±1%~±0.5%)更适合仪器校准、精密信号调理等对偏差敏感的应用。
温度系数为**±25ppm/℃**,表示阻值随温度变化的速率。以100kΩ为例,每升高1℃阻值变化约2.5Ω;温度变化100℃时,阻值变化仅250Ω,仍远低于±0.1%(100Ω)的精度范围,确保宽温环境下性能稳定。
覆盖**-55℃~+155℃**,符合工业级宽温要求,可适应汽车发动机舱、户外工业设备等极端环境,在高低温循环中无明显性能漂移。
采用0805封装(英制:0.08″×0.05″,公制:2.0mm×1.2mm),属于小型贴片封装,适合高密度PCB布局,可通过自动化贴装设备实现高效生产。产品符合RoHS环保标准,无铅无卤,满足全球电子行业环保法规要求。
Viking(光颉)是全球知名被动元件制造商,专注电阻研发30余年,薄膜电阻工艺成熟。AR05BTCW1003经过严格可靠性测试:
基于高精度、宽温、小封装特点,该电阻广泛应用于:
该产品平衡了精度、稳定性与成本,是精密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.
