SC0805J4701F4ANRH是信维通信(Sunway)推出的0805封装通用厚膜贴片电阻,针对中小功率电路设计,平衡了性能、成本与可靠性。核心参数清晰覆盖基础电子系统需求:
4.7kΩ是电子电路中分压、限流、偏置的常用阻值,适配多数模拟信号调理(如音频放大偏置)、电源反馈(如DC-DC输出调节)场景。±5%精度属于通用级,避免了精密电阻的成本冗余,适合对阻值稳定性要求不苛刻的电路。
额定功率125mW是0805厚膜电阻的典型值,可支撑中小信号电流(如最大电流≈5.2mA时,功耗未超额定)。需注意:实际电压受功率约束——若仅按150V计算,150V²/4.7kΩ≈4.9W(远大于125mW),因此使用时需以「功率≤125mW」为核心限制。
±100ppm/℃的温度系数表示:温度每变化1℃,阻值漂移±0.01%。例如,在-55℃到+100℃的宽温范围内,阻值最大漂移仅±1.55%,可满足工业户外、车载辅助系统等高低温场景的稳定性需求。
工作温度覆盖-55℃+155℃,超过消费电子(0℃70℃)的常规要求,适配工业控制、汽车电子等对环境耐受性较高的领域,减少因温度变化导致的电路失效风险。
SC0805J4701F4ANRH因参数均衡,广泛应用于:
该产品以成熟工艺与可靠参数,成为中小功率电路的高性价比选择,适配多领域电子系统的基础设计需求。

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.
