KOA RK73H1JTTD56R2F 产品概述

一、产品简介

KOA RK73H1JTTD56R2F 是一款车规级厚膜芯片电阻,封装为 0603(1608 公制),标称阻值 56.2 Ω,精度 ±1%,额定功率 0.125 W(125 mW),温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ 至 +155℃。该系列满足 AEC‑Q200 汽车级可靠性要求,并具备防潮设计,适合在要求稳定性与可靠性的汽车及工业电子系统中使用。

二、主要特点

  • 阻值:56.2 Ω,精度 ±1%(1/100)
  • 功率:0.125 W(0603 标准额定)
  • 温度特性:TCR ±100 ppm/℃,在宽温区间保持良好的一致性
  • 工作温度范围:-55℃ ~ +155℃
  • 工艺与结构:厚膜(Thick Film)制程,工艺成熟、成本与可靠性平衡良好
  • 汽车级认证:符合 AEC‑Q200 要求,适用于车载电子应用
  • 防潮处理:封装与制程考虑到了湿气敏感性,便于在严苛环境下长期使用

三、电气与热特性要点

  • 直流阻抗稳定,低噪声,适合作为分压、检测、限流与阻抗匹配元件
  • 在高温或高功率工况下需要按厂商给出的功率/温度降额曲线使用,以避免长期过热导致性能退化
  • TCR ±100 ppm/℃ 意味着在温度变化时阻值的漂移受控,适合对温度敏感度一般的应用场景

四、可靠性与一致性

  • AEC‑Q200 认证保证了在振动、热冲击、恒定应力等汽车级试验下的可靠性
  • 厚膜工艺在批次间具有良好的一致性,并通过严格的电气测试与筛选,适合批量生产与长期服役的系统

五、典型应用场景

  • 汽车电子:车身控制模块、传感器前端、车载信息娱乐与仪表板电路
  • 电源管理:分压采样、电流检测(与精密运放配合)与阻抗匹配
  • 工业与通信设备:信号衰减、终端匹配及一般用途的限流或偏置电阻

六、封装与焊接建议

  • 封装:0603(1608 公制),适合高密度 PCB 布局
  • 焊接工艺:建议遵循无铅回流焊规范,控制峰值温度与时间(参照 PCB 与元件制造商的回流曲线)
  • PCB 尺寸与焊盘:建议参考 IPC‑7351 或 KOA 官方推荐的焊盘布局,以保证可靠焊接与热散逸
  • 处理与装配:在贴片、回流及清洗等工序中避免机械应力与过热,防止电阻裂纹或阻值漂移

七、使用注意与采购信息

  • 在高温或高功率应用中,务必参照厂方的功率降额曲线进行设计;长时超额使用会缩短寿命
  • 0603 为小封装,装配时注意贴装精度与回流曲线控制,避免热应力或焊接缺陷
  • 由于为厚膜构造,若需极低噪声或极高精度(ppm 级)场合,应评估是否选用金属膜或薄膜电阻
  • 型号:RK73H1JTTD56R2F,品牌:KOA。如需整卷、带装或样片,请向授权分销/销售渠道索取更详细的库存与交付信息

如需更详细的电气特性曲线(功率‑温度降额、阻值漂移随温度曲线、冲击与振动测试数据)或推荐焊盘尺寸与回流曲线,我可以根据 KOA 的器件资料为您整理具体参数与设计建议。

Sourcing availability signal

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
