RTT021602FTH是台湾旺诠(RALEC)推出的0402封装厚膜贴片电阻,属于中高精度、小功率被动元件,聚焦小型化电子设备与工业级场景的稳定需求,以宽温适应性、高一致性为核心优势,适配主流SMT自动化生产流程。
该产品的核心参数围绕“稳定、精准、小型化”设计,具体如下:
固定阻值为16kΩ,采用厚膜印刷+烧结工艺实现精准阻值控制,精度等级为**±1%**(即实际阻值偏差≤160Ω),满足大多数中高精度电路的设计需求(如信号放大、分压电路),无需额外校准即可稳定工作。
额定功率为62.5mW,是0402封装厚膜电阻的常规功率等级,适配低功耗电路的负载要求;最大工作电压50V,在额定功率范围内可稳定承载电压信号,避免击穿风险,适合低电压信号调理场景。
温度系数为**±100ppm/℃,表示每变化1℃,阻值变化量≤1.6Ω(16kΩ×100ppm),温度稳定性良好;工作温度范围覆盖-55℃~+155℃**,符合工业级宽温标准,可在极端环境(如户外设备、工业现场)下持续工作。
采用厚膜浆料印刷+高温烧结工艺,通过精准的浆料配比、网版控制,保证批量产品的阻值离散性≤±0.5%(远低于精度要求),提升电路设计的可复制性,降低生产调试成本。
该产品采用0402封装(英制:0.04″×0.02″,公制:0.4mm×0.2mm),是目前小型化电子设备中应用最广泛的贴片封装之一:

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
