RMS04FT5100 产品概述

一、产品简介

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。

二、主要性能特点

  • 高精度:±1% 阻值公差,适用于要求较高的分压、阻抗匹配与回授电路。
  • 微型封装:0402 尺寸便于高密度贴装,节省 PCB 面积。
  • 宽温度范围:-55 ℃ ~ +155 ℃,满足工业级环境的温度需求。
  • 良好的一致性:厚膜工艺稳定,适合大批量生产与标准化装配。
  • TCR ±100 ppm/℃,在一般精密电路中能提供可预测的温漂特性。

三、典型电气与物理参数(关键)

  • 阻值:510 Ω
  • 精度:±1%
  • 额定功率:62.5 mW(1/16W)
  • 额定工作电压:50 V(注意:此为结构耐压限制,实际允许电压还需受功率限制约束,见下文说明)
  • 温度系数:±100 ppm/℃
  • 工作温度:-55 ℃ ~ +155 ℃
  • 封装:0402(约 1.0 × 0.5 mm)

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。

四、典型应用场景

  • 移动与便携设备的分压/限流与阻值网络
  • 精密模拟电路、滤波和阻抗匹配场合(对 TCR 与精度有中等要求时)
  • 高密度 PCB、物联网模组、可穿戴设备与消费类电子
  • 电源检测、参考电路与信号链的微型化布局

五、安装与焊接建议

  • 推荐与标准无铅回流工艺兼容,遵循 J-STD-020 之回流曲线,回流峰值温度通常不超过 260 ℃。
  • 0402 封装易受搬运与焊接应力影响,回流时应控制热冲击与机械震动。
  • 波峰焊对该尺寸器件并非最佳选择,建议采用 SMT 贴装与回流焊流程。
  • 储存与贴片前避免受潮,必要时采用干燥箱或按湿敏等级处理。

六、可靠性与使用建议

  • 长期可靠工作时建议对功率进行适当降额(尤其在高环境温度下),以延长寿命并降低热漂;常见工程实践是将实际工作功率保持在额定值的 50% 以下,或根据系统热设计进行更精确的降额计算。
  • 对温度敏感的精密应用,应以 TCR ±100 ppm/℃ 为基准进行温度补偿或电路标定。
  • 该器件为厚膜工艺,噪声与长期漂移性能与薄膜相比略逊一筹,需在超高稳定性场合评估替代方案。

七、包装与订购信息

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。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
