RK73H1ETTP1005F — KOA 0402 厚膜贴片电阻产品概述

一、产品简介

RK73H1ETTP1005F 为 KOA 推出的厚膜贴片电阻,封装规格为 0402(公制 1005,约 1.0 mm × 0.5 mm)。阻值 10 MΩ,精度 ±1%,额定功率 100 mW,最大工作电压 75 V,温度系数 ±200 ppm/℃,工作温度范围 -55℃ ~ +155℃。该器件适合高阻值、空间受限的表面贴装电路,兼顾精度与体积要求。

二、主要性能亮点

  • 高阻值与高精度:10 MΩ 阻值配合 ±1% 精度,满足对阻值稳定性要求较高的测量与偏置电路需求。
  • 小型化封装:0402 尺寸利于高密度布板和微型化产品应用,节省 PCB 面积。
  • 宽温度范围:-55℃ 至 +155℃ 的耐温能力,适用于工业级和严苛环境下的长期工作。
  • 可接受的温漂:±200 ppm/℃ 的温度系数在厚膜同类产品中表现常见,适合一般精度等级的温度变化场景。
  • 适配表面贴装工艺:适用于常规回流焊流程,便于自动化贴装与量产。

三、典型应用场景

  • 高阻抗输入与偏置电路:例如运放输入网络、检波器与高阻测量接口。
  • 测量与分压网络:用于高阻值分压、隔直流测量、漏电流受限电路(注意工作电压限制)。
  • 耐环境装置:工业控制、传感器前端与通信终端等受温度考验的应用。
  • 移动与消费电子:用于体积受限的便携设备中作为限流、泄放或偏置元件。

四、设计与使用注意事项

  • 功率与热管理:额定功率为 100 mW,实际使用时需考虑环境温度与 PCB 散热条件,避免长期在极限功率下工作;在高温环境应适当降额使用。
  • 电压限制:单个元件最大工作电压 75 V,若应用中存在超过此电压的需求,应采用串联电阻或专用高压电阻方案,以防击穿与漏电。
  • 温漂与精度考量:±200 ppm/℃ 的温漂在温度变化大的场合会带来阻值漂移,应在电路容差预算中预留温漂影响。
  • 焊接工艺:支持标准 SMT 回流焊,但建议参考厂方焊接曲线与回流温度上限,控制焊接热应力以保证可靠性。
  • 清洁与后处理:高阻值器件对污染较敏感,贴片后应注意清洗与无腐蚀性清洁剂的使用,避免表面污染导致泄漏电流增大。

五、包装与可靠性

KOA 型号通常以适配 SMT 自动化的卷盘(tape & reel)方式提供,便于大批量生产与点位管理。厚膜结构在常规应用中具备良好的长期稳定性与抗振性能,适配多种工业与消费场景。采购与设计时建议与供应商确认批次、性能一致性测试数据及相关可靠性认证,以满足特殊行业的规范要求。

总结:RK73H1ETTP1005F 在超小体积下提供高阻值与较好精度,适合高阻抗、空间受限且需耐高温的电路设计。设计时需重点关注功率、工作电压与环境温度对电阻表现的综合影响,以保证系统的稳定性与可靠性。若需更详细的电气特性曲线、焊接曲线或可靠性数据,可向 KOA 授权分销或技术支持索取完整规格书。

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
