AR03BTCX1000是Viking光颉推出的精密薄膜贴片电阻,核心针对对阻值精度、温度稳定性、环境适应性要求严苛的中高端电子领域,典型应用覆盖三类场景:
该产品的核心参数围绕“精密稳定”设计,各项指标均优于普通厚膜电阻:
阻值100Ω,精度±0.1%——实际阻值范围仅99.9Ω~100.1Ω,无需额外校准即可满足精密电路的一致性要求(如音频设备的声道平衡、传感器的信号放大)。
±25ppm/℃——远低于普通厚膜电阻(通常±100ppm/℃以上)。举例:当环境温度从25℃升至125℃(工业高温),阻值变化仅0.025Ω(100Ω×100℃×25ppm),仅0.025%,大幅降低温度对电路性能的影响。
-55℃+155℃——覆盖工业级(-40125℃)、汽车级(部分要求-40~150℃)标准,可适应户外通信设备的低温(-55℃)、工业烤箱附近的高温(155℃)场景。
AR03BTCX1000采用薄膜电阻工艺+优化封装结构,保障长期可靠性:
采用真空溅射薄膜技术(而非厚膜印刷),膜层均匀性提升30%以上,结合激光微调保证阻值精度达标;相比厚膜电阻,长期使用后阻值漂移降低50%。
多层端电极设计(镍层+锡层):
产品通过严苛可靠性验证:
Viking光颉作为全球精密电阻龙头,为AR03BTCX1000提供三重保障:
成立于1986年,专注精密电阻研发30余年,拥有120+专利,产品覆盖全球20+国家,是华为、西门子等企业的核心供应商。
Viking光颉AR03BTCX1000凭借“高精度、低TCR、宽温范围、小体积”四大核心优势,成为医疗、工业、通信领域的可靠元件选择——既解决了精密电路的性能稳定性问题,又适配高密度PCB设计与自动化生产,是工程师提升产品竞争力的实用工具。
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.
