Viking光颉AR06BTCV1500是一款高精度薄膜贴片电阻,属于光颉电子的常规精密电阻系列。产品采用1206(英制封装,对应公制3216)贴片封装,核心参数明确:150Ω固定阻值、±0.1%精度、125mW额定功率,工作温度范围覆盖-55℃至+155℃,满足工业级、汽车电子等严苛场景的应用需求。作为薄膜电阻,其相比碳膜/金属膜电阻具备更低噪声、更高温度稳定性的特点,适合对信号精度要求苛刻的电路设计。
产品标称阻值为150Ω,精度等级达±0.1%——这意味着常温下实际阻值与标称值的偏差不超过0.15Ω,能精准匹配精密信号调理、反馈回路等对阻值一致性要求高的场景(如医疗设备的生命体征信号采集)。
温度系数(TCR)为±25ppm/℃,即温度每变化1℃,阻值变化仅约3.75mΩ(150Ω×25×10⁻⁶)。该参数在工业级电阻中属于较高规格,确保宽温环境下阻值稳定,无需额外温度补偿。
覆盖-55℃至+155℃,符合MIL-STD-883工业标准,可适应寒带户外设备(低温)、汽车发动机舱(高温)等极端场景。
光颉采用镍铬薄膜工艺,相比传统电阻具备三大优势:
数字示波器、高精度万用表的信号放大/滤波回路,利用±0.1%精度和低噪声特性,确保测量结果准确。
PLC模拟量输入/输出模块、传感器信号调理电路,宽温范围可适应工厂车间的温度波动。
基站射频前端衰减器、电源反馈回路,1206封装适配基站PCB高密度设计,低噪声不影响信号质量。
车载胎压监测、氧传感器的信号处理电路,-55℃~+155℃温度范围覆盖发动机舱高温区域,满足汽车级可靠性要求。
监护仪、呼吸机的精密模拟电路,高稳定性确保生命体征信号采集准确,符合医疗安全标准。
实际工作功率≤100mW,避免过热导致阻值漂移或寿命缩短。
电阻两端电压≤200V(有效值),高压场景需串联电阻分压。
回流焊峰值温度≤260℃(持续≤10秒),手工焊接温度≤350℃,避免损坏薄膜层。
未开封产品存于0℃~40℃、湿度<60%环境;开封后未使用需防潮袋密封,避免受潮影响焊接。
该产品凭借高精度、宽温稳定、小体积等特点,成为工业控制、医疗、汽车电子等领域的高性价比选型。

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.
