RTT022613FTH 为 RALEC(旺诠)出品的一款高阻值、低功耗 0402 封装厚膜贴片电阻。标称阻值 261 kΩ,精度 ±1%,额定功率 62.5 mW,额定工作电压 50 V,温度系数(TCR)±100 ppm/°C,工作温度范围 -55 ℃ ~ +155 ℃。适配现代高密度 SMT 板面,适用于对体积、稳定性和成本有综合要求的电子产品。
实际使用时可作简单功率/电压校验:在额定工作电压 50 V 时,电流 I = 50 V / 261 kΩ ≈ 192 μA,功耗 P = V^2/R ≈ 9.6 mW,远低于 62.5 mW 的额定功率,留有较大的安全余量。若仅按功率计算的最高跨压为 sqrt(P·R) ≈ 127.8 V,但器件的额定工作电压以 50 V 为限,禁止超压使用。
总结:RTT022613FTH 是一款适合高阻值、体积受限应用的 0402 厚膜贴片电阻,具备 ±1% 精度和良好的功率裕度。选型时应综合考虑温漂、噪声与环境工况,按厂商推荐的焊接与储存规范使用,以确保长期可靠性。

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.
