0805W8F3003T5E 是 UNI-ROYAL(厚声)系列的厚膜贴片电阻,封装为0805(约2.0 × 1.25 mm)。标称阻值为 300 kΩ,精度 ±1%,额定功率 125 mW,额定工作电压 150 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55 ℃ 至 +155 ℃。该器件面向对高阻值、高精度和标准表面贴装工艺兼容的通用电子产品及工业应用。
该系列电阻设计用于满足电子产品常见的可靠性要求,通常经过焊接热冲击、温度循环、负载寿命与湿热试验等项目验证。对于高温或持续大功率工况,应参照厂方提供的功率降额曲线(Power derating)与寿命测试数据,合理留有余量以确保长期可靠性。
典型料号 0805W8F3003T5E 中“0805”表示封装规格,“3003”对应厂方阻值标识(300 kΩ),后缀通常包含包装形式(例如卷带/盘装等)。实际包装单位(卷带数量)与交付条件请参照 UNI-ROYAL 的产品目录或向供应商确认。
备注:以上为基于常规规格与应用整理的概述性说明。对更详细的电气特性、功率降额曲线、可靠性试验数据与推荐回流曲线,请参阅厂方完整数据手册或直接咨询 UNI-ROYAL(厚声)技术支持。

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.
