0805W8F6800T5E 为 UNI-ROYAL(厚声)系列厚膜贴片电阻,封装尺寸为 0805,阻值 680Ω,精度 ±1%,额定功率 125mW,工作温度范围 -55℃ ~ +155℃,温度系数(TCR)±100ppm/℃。该器件适用于对阻值精度和温度漂移有中等要求的 SMT 电路,常用于信号处理、偏置、分压及一般电子产品中。
注:电阻两端实际允许的最大连续电压还需满足功率限制。按 P = V^2 / R 计算,若仅按功率额定,则最大允许电压 Vmax ≈ sqrt(0.125W × 680Ω) ≈ 9.2V。即在超过此电压时,器件会因功耗超过额定值而失效;150V 为器件的耐压上限,而非在额定功率下可长期承受的电压。
如果需要,我可以根据您的具体应用工况(工作电压、环境温度、贴片板材与面积)帮您计算实际功率降额和推荐替代型号。

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.
