1206W4J0331T5E 是 UNI-ROYAL(厚声)系列的贴片厚膜电阻,封装为 1206(约 3.2 × 1.6 mm),阻值 330Ω,精度 ±5%,额定功率 0.25W,额定工作电压 200V。工作温度范围为 -55℃ 至 +155℃,温度系数(TCR)为 ±100 ppm/℃。该型号面向通用电子装配场景,兼顾成本与可靠性,适合大批量表面贴装生产。
采用厚膜电阻工艺,阻性薄膜印刷在陶瓷基体上,经高温烧结而成。该结构在成本与批量一致性上具有优势,端接具有良好的焊接性以适配回流焊工艺。由于为厚膜元件,其在热噪声、频率响应及高频寄生方面与薄膜电阻存在差异,适合一般直流与低频交流应用。
常见为卷带(Tape & Reel)包装,便于贴片机取放。厚膜工艺在耐湿、耐振方面具有良好表现,具体可靠性指标(如寿命、耐潮湿试验、焊接热冲击等)请参考厂商完整数据手册或出具的可靠性报告。

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.
