0805W8F3000T5E是UNI-ROYAL(厚声) 推出的厚膜贴片电阻,采用行业通用0805封装(尺寸约2.0mm×1.2mm),核心参数匹配中低功耗、中等精度的电子电路需求:
作为厚膜电阻,该产品通过厚膜印刷+高温烧结工艺 实现性能平衡:
±1%的阻值精度可覆盖消费电子、工业控制的基础需求(如传感器信号分压、电路偏置);±100ppm/℃的温度系数意味着:当环境温度从-55℃变化到+155℃(温差210℃),阻值最大漂移量为300Ω×210×0.0001=6.3Ω,仍在±1%精度范围内,不影响电路核心功能。
125mW额定功率适合低功耗场景(如手机主板小信号电路、LED指示灯限流);150V工作电压可覆盖中等电压电路(如24V工业电源分压监测、12V车载辅助电路),无需额外串并联电阻,简化设计。
-55℃~+155℃宽温范围是核心优势:在汽车发动机舱(最高120℃以上)、北方户外工业设备(最低-40℃以下)等场景中,仍能保持稳定性能,无需额外加温控措施。
该产品以高性价比、宽温稳定的特点,成为0805封装厚膜电阻的主流选型之一,适配多领域电子电路的基础电阻需求。

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.
