Viking光颉ARG03FTC4992是一款0603封装精密薄膜贴片电阻,专为高密度、高稳定性电子电路设计。该产品以49.9kΩ标称阻值、±1%精度为核心参数,继承光颉薄膜电阻的工艺优势,适配工业控制、消费电子、医疗设备等多领域需求,兼顾体积小型化与性能可靠性。
标称阻值为49.9kΩ,精度等级达**±1%**——该精度无需额外校准,可直接用于信号调理、分压电路等对阻值偏差敏感的场景,降低电路设计复杂度。
最大额定功率为100mW,符合0603封装贴片电阻的常规功率规格。实际应用需遵循温度降额原则:环境温度超过25℃时,需根据温度系数适当降低工作功率(如125℃时降额至70%左右)。
最大工作电压为75V,是重要安全参数——电路中需确保电阻两端电压不超过此值,避免绝缘击穿或性能退化。
温度系数为**±25ppm/℃**,属于薄膜电阻的低TCR范围。该参数表示:温度每变化1℃,阻值变化量约为49.9kΩ×25ppm≈1.25Ω,远优于碳膜电阻(通常>500ppm/℃),适配温度波动较大的工业环境。
ARG03FTC4992采用0603英制封装(对应公制1608,长1.6mm×宽0.8mm),体积小巧,可有效节省PCB空间,适配手机、基站等高密度布局设计。封装结构为耐高温陶瓷基片+金属薄膜电阻层,焊接兼容性强,支持回流焊、波峰焊等常规贴片工艺,焊接后无虚焊、脱落风险。
ARG03FTC4992的工作温度范围为**-55℃~+155℃**,覆盖工业级温度要求,可在极端高温/低温环境下连续工作。此外,薄膜电阻结构耐老化,长期使用阻值变化率<0.1%(1000小时高温老化后),可靠性远超普通碳膜电阻。
ARG03FTC4992凭借高稳定性、小体积与宽温适应性,成为精密电子电路中替代普通碳膜电阻的理想选择,尤其适合对精度、可靠性要求严格的工业与医疗领域。

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.
