CN24JTN221 排阻产品概述
一、产品基本属性
CN24JTN221是大毅科技推出的一款四合一贴片排阻，属于0402x4封装系列。该产品集成4个独立电阻元件，通过8引脚设计实现紧凑布局，可替代传统4个0402封装的离散电阻——既能节省PCB空间（尤其适合高密度电路），又能减少焊接工序，提升电路设计与生产效率。
二、关键性能参数解析
作为常规中精度排阻，CN24JTN221的核心参数适配多数低功耗电路需求：
- 阻值与精度：每个电阻标称阻值220Ω，精度±5%。无需高精度校准的场景下，可满足信号分压、限流、滤波等基础功能，避免不必要的成本冗余；
- 功率规格：单个元件额定功率62.5mW，单排阻总功率250mW（4×62.5mW）。适配小电流场景（如≤16.7mA的限流需求，计算逻辑：(I=\sqrt{P/R}=\sqrt{62.5e-3/220}≈16.7mA)）；
- 温度系数：±250ppm/℃，即温度每变化1℃，阻值变化±0.055Ω。在-40℃~85℃的常规工作温度范围内，阻值最大变化约±1.375Ω，稳定性满足普通消费电子、通信设备的环境要求；
- 元件与引脚：4个独立电阻+8引脚设计（2端×4），可灵活配置为串联（4个串联得880Ω）、并联（得55Ω）或独立使用，适配不同电路拓扑。
三、封装与引脚配置
CN24JTN221采用0402x4封装，即4个0402标准贴片电阻（单电阻尺寸0.4mm×0.2mm）集成在同一封装内，总封装尺寸紧凑，适合智能手机主板、智能穿戴模块等高密度PCB设计。8引脚采用双侧布局（参考 datasheet 确认），焊接兼容性与离散0402电阻一致，可通过SMT自动贴装，生产效率显著高于离散电阻方案。
四、典型应用场景
CN24JTN221的参数特性使其适配以下场景：
- 消费电子：智能手机/平板的触控面板信号分压、LED背光驱动限流、按键电路信号滤波；
- 通信设备：小型基站、路由器的信号滤波网络、电源模块分压取样、WiFi模块信号匹配；
- 智能穿戴：智能手表/手环的心率传感器信号调理、低功耗LED指示、按键电路限流；
- 工业控制：小型传感器模块分压、低功耗PLC输入输出接口限流、微型电机驱动电流检测。
五、品牌与品质保障
大毅科技作为专业被动元器件制造商，CN24JTN221符合RoHS 6.0、REACH等环保法规，生产过程通过ISO9001质量体系认证。产品经过高温老化（125℃/1000h）、湿度循环（85℃/85%RH/500h）等可靠性测试，可满足批量生产中的稳定性需求，降低售后返修率。
该产品定位中低端常规电路，在“紧凑布局+基础性能+成本控制”之间实现平衡，是消费电子、通信设备等领域的实用型排阻选择。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
