RMS04FT5100 为大毅科技(Dayi)出品的片式厚膜电阻,封装为 0402(公制 1005,约 1.0 mm × 0.5 mm),阻值 510 Ω,精度 ±1%(E96 系列),额定功率 1/16W(62.5 mW),额定工作电压标称 50 V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55 ℃ ~ +155 ℃。该型号针对高密度 SMT 布局与微型化电子产品设计,兼顾尺寸小、精度高与宽温度适应能力。
说明:依据 P = V^2 / R,可算出在 510 Ω 下达到额定 62.5 mW 的电压约为 5.65 V(V = sqrt(P·R))。因此在电路设计中务必保证工作电压与功率消耗均不超过器件额定值;50 V 为最大允许电压(绝缘/击穿限制),但远高于由功率决定的工作电压。
RMS04FT5100 常见以卷带(Tape & Reel)方式供货,适配自动贴装生产线。常见卷盘数量可按需求提供(如 3,000 / 5,000 / 10,000 PCS 等)。订购时请注明阻值、精度、封装及所需包装形式。

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.
