0402WGF3302TCE 是 UNI‑ROYAL(厚声)推出的一款高密度贴片厚膜电阻。该器件为 0402 小封装(约 1.0 mm × 0.5 mm),标称阻值 33 kΩ,精度 ±1%,额定功率 62.5 mW(1/16W),工作电压 50 V,温度系数 ±100 ppm/℃,工作温度范围 −55℃ 至 +155℃。此型号以体积小、成本友好、可靠性良好为特点,适合空间受限的高密度电路板与通用电子应用。
0402WGF3302TCE 采用厚膜工艺制造,电阻体由金属氧化物浆料经印刷和烧结形成,端接为金属化电极,表面有保护涂层以提高抗潮湿和耐焊性。0402 尺寸小,适用于高密度 SMT 布局。厚膜电阻在常温下表现稳定,具有良好的机械强度和可量产性。
0402WGF3302TCE 工作温度范围宽(−55℃ 至 +155℃),适合在较严苛温度环境中长期使用。厚膜材料对湿热、热冲击具有较好承受能力,但具体寿命与可靠性仍依工况(如功耗、循环温度应力、焊接条件)而异。常见可靠性试验包括高温储存、热冲击、湿热试验及焊接耐久性测试,建议在产品导入前参考供应商的可靠性报告或自行作针对性验证。
下单时请注明完整型号 0402WGF3302TCE、阻值及精度要求、包装方式(带卷 tape & reel)和所需数量。常见卷带包装数量可按客户需求提供(如 5,000 或 10,000 颗/卷)。如需替代型号或不同温漂、功率等级,请与供应商技术支持沟通以获得最合适的替代方案。
总结:0402WGF3302TCE 以其小尺寸、1% 精度和宽温工作特性,适合高密度贴装与通用低功耗电路。采用前应关注回流焊工艺和功率降额设计,必要时进行针对性可靠性验证以确保在目标应用中的长期稳定性。

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.
