AR03BTD1002是Viking(光颉) 品牌旗下的高精度薄膜贴片电阻,采用行业通用的0603封装(英制尺寸,对应公制1608),属于针对小型化、高稳定性电路设计的核心无源器件。该产品以薄膜电阻工艺为核心,兼顾精度、温度稳定性与紧凑体积,是工业控制、车载电子、便携式设备等领域的常用选型。
额定阻值为10kΩ,精度等级达**±0.1%**——此精度在常规贴片电阻中属于较高等级,可有效降低电路设计中的系统误差。例如在运放反馈网络、基准电压分压电路中,±0.1%的偏差能避免信号放大失真或分压不准,适合对阻值一致性要求严格的场景。
最大耗散功率为62.5mW(0.0625W),额定工作电压为50V——功率值符合0603封装的常规功率范围,50V电压额定值可满足大多数低压模拟电路的工作需求(实际应用中需注意功率/电压不得超过额定值,避免电阻过热损坏)。
温度系数为**±50ppm/℃**——表示温度每变化1℃,阻值变化率为±50×10⁻⁶。以10kΩ阻值计算,温度变化10℃时阻值漂移仅±0.5Ω,此参数在薄膜电阻中属于中等偏优,适合温度波动环境下的稳定应用(如车载高温/低温场景)。
覆盖**-55℃+125℃**——超出一般工业级(-40℃+85℃)的温度范围,可适配车载、航空航天等高低温严苛场景,满足极端环境下的长期稳定工作。
体积紧凑(1.6mm×0.8mm),适合高密度PCB布局,可有效缩小产品尺寸,满足智能手机、智能穿戴等便携式设备的小型化需求,同时兼容自动化贴片生产,降低制造成本。
相比厚膜电阻,薄膜工艺具有三大核心优势:
AR03BTD1002采用无铅焊接工艺,符合RoHS环保标准,同时具备良好的抗振动、抗冲击性能(贴片封装优势),可在移动或振动环境下稳定工作。薄膜电阻的长期可靠性表现优异,阻值漂移率极低(通常小于0.1%/1000小时),适合对产品寿命要求高的领域。
综上,AR03BTD1002以高精度、宽温稳定、紧凑体积为核心优势,是小型化、高可靠性电路设计的理想无源器件选型。

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.
