Viking(光颉)推出的AR03BTCX7801N是一款0603封装贴片薄膜电阻,核心规格清晰明确:
该产品基于薄膜电阻技术打造,兼顾高精度与环境稳定性,适配对参数一致性要求严格的电子设计场景。
标称阻值7.8kΩ的精度达±0.1%,可直接满足多数精密电路对电阻偏差的严苛要求(如传感器信号调理、仪器校准电路),无需额外匹配电阻即可实现信号精度达标,减少设计冗余。
±25ppm/℃的TCR意味着阻值随温度变化的漂移极小:以工作温度范围(-55℃~+155℃,温差210℃)为例,阻值最大变化量仅约0.395Ω,远低于精度阈值,适合宽温环境下的长期稳定应用。
100mW额定功率匹配低功耗电路设计(如物联网终端、小型通信模块),常规使用无需额外降额,可稳定承载电路负载,同时降低整体功耗。
相比厚膜电阻,薄膜电阻采用真空沉积工艺形成电阻层,具有更低噪声系数(典型值<1nV/√Hz)、更好线性度,适合模拟电路、射频前端等对信号质量敏感的场景。
采用0603英寸标准贴片封装(公制尺寸:1.6mm×0.8mm×0.45mm,典型值),符合国际电子封装标准:
该产品因高精度、宽温稳定、小封装等特性,广泛适用于以下领域:
AR03BTCX7801N凭借高精度、宽温稳定、小封装及薄膜电阻的低噪声优势,成为7.8kΩ阻值场景下的优选贴片电阻,可有效支撑工业、医疗、通信等领域的精密电子设计需求。

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.
