AR03BTCX1502是光颉(Viking)电子推出的高精度薄膜贴片电阻,针对小型化、高精密电路设计需求打造,核心优势在于低阻值误差、低温度系数及宽温适应性,可满足工业控制、通信、医疗等领域对电阻性能的严苛要求,是替代普通厚膜电阻的高性价比选择。
阻值规格为15kΩ,精度达**±0.1%**——相比普通厚膜电阻±1%~±5%的精度,该参数可将电路信号调理误差控制在极小范围(如15kΩ电阻的实际误差仅±15Ω),适合运算放大器反馈网络、精密分压电路等对阻值精度敏感的场景,避免因阻值偏差导致电路输出失真。
额定功率为100mW,满足小功率模拟/数字电路的常规负载需求,且薄膜工艺可保证功率负载下的阻值稳定性,长期工作时无明显漂移,无需额外降额设计即可覆盖多数应用场景。
温度系数为**±25ppm/℃**,远低于厚膜电阻(通常±100ppm/℃以上)。该参数意味着温度每变化1℃,阻值仅变化±0.375Ω(15kΩ×25ppm);若温度变化100℃,阻值变化仅±37.5Ω,可有效抑制宽温环境下电路性能波动,确保设备在极端温度下稳定工作。
覆盖**-55℃~+155℃**的宽温区间,可适应工业现场低温环境(如北方户外传感器节点)及高温工况(如电源模块内部),无需额外散热或防护设计即可稳定运行。
采用0603封装(英制尺寸:0.06″×0.03″,公制1608),尺寸仅1.6mm×0.8mm,适合高密度PCB设计(如智能手机、路由器等小型化设备),可显著节省电路板空间,提升电路集成度。
基于光颉多年积累的真空溅射薄膜技术,通过在高纯度氧化铝陶瓷基底上沉积镍铬合金电阻膜,相比厚膜工艺具有三大优势:
AR03BTCX1502具备良好的可靠性,可通过多项行业标准测试:
该电阻广泛适用于对精度、稳定性要求较高的场景:
AR03BTCX1502凭借**±0.1%高精度、±25ppm/℃低温度系数、宽温适应性及小型化封装**,成为光颉薄膜电阻系列中的经典型号,可有效解决精密电路设计中的阻值误差与温漂问题,是工业、通信、医疗等领域的可靠选择,同时兼顾成本与性能平衡,适合批量应用。
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.
