0805W8F4701T5E 是 UNI-ROYAL(厚声)出品的一款薄膜/厚膜贴片电阻(厚膜电阻),封装为0805(2012公制)。标称阻值为 4.7 kΩ,精度 ±1%,额定功率 125 mW,最高额定工作电压 150 V,温度系数(TCR)典型值为 ±100 ppm/℃,工作温度范围为 -55℃ 至 +155℃。该产品针对中高密度贴装电路设计,兼顾尺寸小型化与可靠性,适用于一般信号与偏置网络、滤波、分压和阻抗匹配等场合。
0805 封装体积小,适合高密度 PCB 布局。厚膜工艺通过在陶瓷基板上丝网印刷金属氧化物电阻膜并经烧结形成,端电极采用贵金属/镀层处理以保证可焊性和机械强度。该产品在体积受限且对温漂、精度有一定要求的电路中能提供稳定的阻值表现,同时具有成本优势。
典型外形尺寸(参考0805国际标准):
如需完整的电气特性曲线、功率随环境温度的降额曲线或焊接工艺规范(具体回流曲线、储存寿命、寿命加速试验数据等),建议联系 UNI-ROYAL(厚声)或代理商获取该型号的详细技术资料(Datasheet)。

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.
