PJ-342C CB 3.5mm SMD耳机座产品概述

一、产品核心定位与应用场景

PJ-342C CB是首韩(SHOU HAN)推出的SMD封装3.5mm音频连接器,专为小型化、高可靠性音频设备设计,兼顾信号传输稳定性与自动化生产兼容性。其核心定位是替代传统插件式耳机座,适配消费电子、车载、医疗等领域的紧凑布局需求,同时满足宽温环境下的长期稳定工作。

应用场景覆盖三类典型场景:

  1. 消费电子:便携式蓝牙音箱、数码录音笔、MP3播放器的音频输入/输出接口;
  2. 车载系统:中控音频监听接口(适配-20℃~80℃的车载温区);
  3. 医疗设备:监护仪、输液泵的音频报警输出接口(依赖高可靠性与信号无干扰)。

二、基础电气与环境参数

PJ-342C CB的核心参数符合行业通用标准,同时匹配目标应用的性能需求:

参数类别 具体指标 备注 连接器类型 3.5mm立体声耳机座 支持双声道音频传输 额定电流 1A(AC/DC) 满足有源耳机、小功率音频设备 额定电压 12V(AC/DC) 符合低电压音频系统安全要求 工作温度范围 -20℃~+80℃ 覆盖车载、户外设备环境 接触电阻 ≤30mΩ(典型值,无负载) 保证音频信号低损耗 绝缘电阻 ≥100MΩ(DC500V,常态) 防止信号串扰 耐压强度 250V AC(50Hz,1min) 无击穿/飞弧风险 环保标准 RoHS 2.0、REACH SVHC 符合全球电子设备环保要求

三、封装与结构特点

PJ-342C CB采用SMD(表面贴装)封装,结构设计围绕生产兼容性与可靠性展开:

  1. 封装适配性:

    • 引脚布局符合IPC-A-610标准,适配主流贴片机(如Yamaha、Fuji);
    • 回流焊耐受温度:峰值260℃±5℃,持续时间≤10s(满足无铅焊接工艺)。
  2. 材质选型:

    • 外壳:黄铜镀镍(厚度≥5μm),抗腐蚀、屏蔽电磁干扰;
    • 触点:磷铜镀金(厚度≥0.3μm),降低氧化风险,提升插拔寿命;
    • 绝缘体:高温尼龙(PA6T),耐高温回流焊,绝缘性能稳定(工作温度内无变形)。
  3. 结构细节:

    • 带定位柱防呆设计,避免贴片方向错误;
    • 插孔防尘盖(可选),减少灰尘进入导致的接触不良;
    • 引脚间距2.54mm(行业标准),兼容通用PCB设计。

四、可靠性与应用优势

PJ-342C CB的可靠性经过多轮测试验证,同时具备明显的应用优势:

  1. 可靠性表现:

    • 插拔寿命:≥5000次(标准插拔测试,无接触不良);
    • 振动测试:10~2000Hz,加速度10g,持续2h(无功能失效);
    • 冲击测试:100g,11ms半正弦波(3个方向,符合IEC 60068-2-27);
    • 温湿度循环:-20℃~80℃,湿度95%RH,循环100次(性能无衰减)。
  2. 应用优势:

    • 小型化:SMD封装节省PCB空间(尺寸约10mm×8mm×5mm),适配便携式设备;
    • 信号稳定:镀金触点+低接触电阻,保证音频信号无失真(无杂音、无延迟);
    • 生产高效:自动化贴片替代人工插件,降低成本30%以上(批量应用);
    • 宽温适配:覆盖车载、户外设备的极端温度,无需额外散热设计。

五、典型应用案例

  1. 便携式蓝牙音箱:某国内品牌音箱采用PJ-342C CB作为音频输出接口,SMD封装适配100mm×60mm的PCB布局,1A电流满足有源耳机的功率需求;
  2. 车载中控:某合资车企的入门级车型中控采用该产品,宽温范围适配-15℃(冬季)至75℃(夏季)的车载环境,黄铜镀镍外壳屏蔽车载电磁干扰;
  3. 医疗监护仪:某医疗设备厂商的监护仪将其作为报警输出接口,镀金触点保证报警音清晰,5000次插拔寿命满足医院24小时连续使用需求。

PJ-342C CB凭借SMD封装的生产优势、宽温环境的可靠性,成为小型化音频设备的优选连接器方案,适合批量应用于消费电子、车载、医疗等领域。

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
