CN34JTN330 排阻产品概述

CN34JTN330是大毅科技推出的一款0603×4封装表面贴装排阻,属于4通道网络电阻器,专为高密度、小型化电子电路设计,兼顾性能稳定性与集成度优势,广泛适用于消费电子、工业控制、通信设备等领域。

一、产品基本属性

该排阻由4个独立的33Ω电阻集成在同一封装内,引脚总数为8(每通道2个引脚),符合表面贴装工艺要求,可通过回流焊、波峰焊等常规工艺焊接。产品采用成熟的薄膜电阻工艺制造,确保阻值一致性与长期可靠性,是离散电阻的高效替代方案。

二、核心性能参数详解

1. 电阻值与精度

标称阻值为33Ω,精度等级为**±5%**,满足多数电子电路的阻值匹配需求(如分压、限流、信号衰减等)。在25℃标准温度下,阻值偏差控制在31.35Ω~34.65Ω范围内,可覆盖常规设计的误差裕量,无需额外校准即可满足多数应用场景。

2. 功率特性

单个电阻的额定功率为62.5mW,4通道总功率为250mW。需注意:工作时每通道的实际功耗不得超过62.5mW(即最大工作电流约13.7mA,计算方式:(I=\sqrt{P/R}=\sqrt{62.5mW/33Ω}≈13.7mA)),避免因过热导致阻值漂移或元件损坏。

3. 温度系数

温度系数为**±200ppm/℃**,表示环境温度每变化1℃,阻值变化量为±200×10⁻⁶×33Ω≈±6.6mΩ。在常规工作温度范围(-55℃~125℃)内,最大阻值漂移约±0.13Ω(180℃温差×6.6mΩ/℃),满足一般工业与民用场景的温度稳定性要求,无需额外温控措施即可稳定工作。

4. 封装规格

采用0603×4封装(英制:0.06英寸×0.03英寸×4通道;公制:1.6mm×0.8mm×4通道),封装尺寸紧凑,相比离散的4个0603电阻,可节省约40%的PCB布局空间,显著提升电路密度,适配穿戴设备、小型通信模块等对体积敏感的设计。

三、引脚与焊接设计

CN34JTN330的8个引脚采用常规表面贴装引脚布局,每通道2个引脚呈线性排列,便于PCB布线(建议焊盘尺寸匹配0603封装标准,宽度0.4mm0.5mm,长度1.2mm1.4mm)。焊接时需遵循大毅科技推荐的回流焊温度曲线(峰值温度245℃±5℃,时间≤30秒),确保每个引脚焊接牢固,避免虚焊或冷焊。

四、典型应用场景

1. 消费电子

  • 按键识别电路:手机、平板的多按键(如音量、电源键)通过4通道电阻分压实现电压识别,减少元件数量与PCB面积。
  • 穿戴设备LED驱动:智能手环、蓝牙耳机的状态指示灯(如充电、连接状态)需多路限流电阻,排阻集成设计适配设备小型化需求。

2. 工业控制

  • 传感器信号调理:小型温度、压力传感器的接口电路中,作为差分信号的终端电阻或分压网络,精度与温度系数满足工业环境(-40℃~85℃)要求。

3. 通信设备

  • 小型路由器/交换机状态指示:集成4个限流电阻为多个LED指示灯供电,简化电路设计,提升生产效率。

五、设计优势

  1. 体积集成优势:4个电阻集成于单一封装,大幅减少PCB占用面积,适配高密度电路设计(如5G小基站、智能音箱的主板)。
  2. 阻值一致性:同一封装内的电阻由同一工艺生产,阻值一致性优于离散电阻(偏差≤±0.1%,离散电阻通常为±0.5%),适合需要匹配电阻的电路(如差分传输线终端)。
  3. 生产效率提升:一次贴装可替代4次离散贴装,减少贴装时间(约节省30%贴装工时)与设备占用,降低制造成本。
  4. 可靠性提升:减少焊接点数量(离散4个电阻需8个焊盘,排阻一次焊接8个引脚),降低虚焊风险(虚焊率降低约20%),提升长期可靠性。

综上,CN34JTN330排阻凭借紧凑的封装、稳定的性能与高集成度,成为小型化电子设备中替代离散电阻的理想选择,适用于多种需要多路电阻网络的应用场景,是大毅科技针对高密度设计推出的高性价比产品。

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.
