RTT021001FTH是RALEC(旺诠) 推出的一款高性能厚膜贴片电阻,采用行业通用的0402封装,专为小体积、宽温域、中等精度的电子电路设计,广泛适配消费电子、工业控制、通信设备等领域的应用需求。
RALEC(旺诠)作为全球知名的被动元器件制造商,以厚膜电阻、片式电感等产品的稳定性和性价比著称。RTT021001FTH是其针对通用电路优化的主力型号,聚焦“小封装+宽温+中等精度”的平衡设计,满足批量生产中对成本、可靠性的双重要求。
该电阻的核心参数直接决定了其应用场景,具体如下:
采用0402封装(英制尺寸:0.04英寸×0.02英寸;公制尺寸:1005,即1.0mm×0.5mm),体积小巧,适合高密度贴装(如智能手机主板、小型通信模块),兼容自动化SMT生产线,生产效率高。
厚膜工艺赋予其抗机械应力、抗潮湿的特性,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好,是平衡“性能-成本-体积”的优选方案。
RTT021001FTH的参数设计使其适配多类场景:
若需替代,可选择同封装、同参数的其他品牌型号(如国巨、三星的0402 1kΩ±1% 1/16W电阻),但RTT021001FTH的±100ppm/℃温漂和宽温范围,在工业级、车载级场景中更具优势;若对精度要求更高(如±0.1%),则需切换至薄膜电阻型号。
综上,RTT021001FTH凭借小体积、宽温域、中等精度的平衡设计,成为通用电子电路中性价比极高的厚膜贴片电阻选择,适配多行业的批量生产需求。

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.
