0603WAJ0681T5E 产品概述

一、产品简介

0603WAJ0681T5E 为 UNI-ROYAL(厚声)系列厚膜贴片电阻,封装为 0603(公制 1608),标称阻值 680Ω,精度 ±5%,额定功率 1/10W(100 mW),工作电压 75V,温度系数(TCR)±100 ppm/℃,工作温度范围 -55℃ 至 +155℃。该型号采用厚膜工艺制成,适用于表面贴装自动化生产线,兼顾小型化尺寸与良好的功率密度与热稳定性,适合工业与消费类电子的常规去耦、分压与限流应用。

二、主要参数与特性

  • 阻值:680Ω(标称)
  • 精度:±5%(J)
  • 额定功率:0.1 W(100 mW)
  • 允许工作电压:75 V
  • 温度系数(TCR):±100 ppm/℃(典型厚膜等级)
  • 工作温度:-55℃ ~ +155℃
  • 封装:0603(1608 公制)表贴
  • 制程:厚膜电阻
  • 品牌:UNI-ROYAL(厚声)
  • 包装方式:适配贴片回流生产(常见为卷装、载带包装)

产品特性:

  • 小体积、适合高密度 PCB 布局
  • 良好的温度漂移控制(±100 ppm/℃ 满足一般工业级需求)
  • 典型的厚膜电阻机械强度与可焊性,适配常规回流焊工艺
  • 宽温范围,可在-55℃至+155℃长期工作

三、封装与物理尺寸

0603(1608)标准封装尺寸(典型值):

  • 长度:1.6 mm
  • 宽度:0.8 mm
  • 厚度:约 0.45 mm(因制造公差略有差异)

该尺寸适合大多数表面贴装元件贴装与飞针/波峰检测工艺,对应常用的 0603 贴装头与回流炉工艺参数。

四、应用场景

  • 通用电子设备中的限流、分压、阻抗匹配与去耦电路
  • 通信设备、模数混合电路的拉/下拉电阻
  • 消费电子(便携设备、传感器模块、遥控与显示驱动等)
  • 工业控制与电源管理(低功率电路、采样分压) 该型号因阻值与功率特点,适合低功耗信号链路或控制类电路,不适合高功率分流或大电流场合。

五、焊接与可靠性建议

  • 焊接方式:兼容无铅回流焊工艺。建议遵循制造商提供的回流曲线,峰值温度通常不超过 260℃,峰值时间与循环数按 PCB 装配规范控制。
  • 清洗与抗焊性:厚膜电阻通常具有良好抗焊性,但在高温回流或多次回流工序中应注意焊盘热量控制与冷却速率。
  • 贮存与搬运:避免潮湿环境长期暴露,建议在干燥、常温条件下存放,防止氧化或包装受潮影响贴装性能。
  • 热管理:此类 0603 小尺寸电阻功率有限,长时间靠近热源或在高环境温度下需考虑降额使用以保证长期可靠性。工作功率应以环境温度和 PCB 散热条件综合评估。

六、选型与替换注意事项

  • 若线路需要更高精度或更低 TCR,可考虑薄膜或金属膜高精度器件;若需更高功率应升级封装(如 1206、2010)或选择更高额定功率型号。
  • 替换时注意尺寸、功率、最大工作电压与温度特性至少相等或更优;封装与焊盘尺寸兼容以保证贴装可靠性。
  • 对于高频或严格阻抗控制的应用,请评估电阻的寄生电感与电容特性。

七、包装与订购建议

0603WAJ0681T5E 常以卷装(Tape & Reel)形式供货,便于 SMT 自动贴装。订购时请确认:

  • 阻值与精度是否满足设计需求(680Ω ±5%)
  • 包装类型与数量(例如 5000 / 10000 卷装等)
  • 是否需要额外的认证或测试报告(如阻值报告、ROHS 合规性声明)

总结:0603WAJ0681T5E 为一款通用型厚膜贴片电阻,适用于对体积敏感且功率需求较低的电路。它在常规温度范围与常见回流工艺下具有稳定的电气特性,是 PCB 高频率分布式电阻与通用信号链电路的经济之选。若需更严格的热稳定性或更高功率,请结合电路实际工况选择更合适的替代产品。

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.
