1206W4F300JT5E 是 UNI-ROYAL(厚声)出品的一款贴片厚膜电阻,采用 1206(英制)封装,标称阻值 30Ω,精度 ±1%,额定功率 0.25W(250mW),最高工作电压 200V。该器件以稳定的电阻特性和较宽的工作温度范围(-55℃ 到 +155℃)适应多种电子设计要求,温度系数为 ±100ppm/℃,适合对温漂有一定要求的应用场景。
典型封装尺寸(参考 1206 标准):约 3.2mm × 1.6mm,适用于自动化贴装与常见 SMT 生产流程。常用供货形式为卷带(Tape & Reel),便于表面贴装设备取料。
这些参数表明该电阻为中低功率、较高精度的通用贴片电阻,适合在温度变化不是极端苛刻但需一定精度的电路中使用。
1206W4F300JT5E(UNI-ROYAL 厚声)是一款面向通用电子设计的高精度厚膜贴片电阻,兼顾尺寸、精度与温度适应性。其 30Ω、±1% 与 250mW 的组合使其在信号处理、分压、限流等场合具有良好的性价比。最终选型与可靠性评估应参照完整数据手册及具体电路工作条件进行校核与验证。若需更详细的电气特性、回流曲线或可靠性试验数据,请向供应商索取完整数据表与检测报告。

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.
