PJ-342 141 3.5mm SMD音频耳机座产品概述

PJ-342 141是SHOU HAN(首韩)品牌推出的一款标准3.5mm音频连接器,采用SMD(表面贴装)封装,专为消费电子及小型音频设备设计,兼具稳定的信号传输性能、便捷的生产适配性与宽环境适应性,可满足多数音频设备的接口需求。

一、产品核心定位与典型应用场景

该产品定位于通用型音频接口,聚焦消费电子领域的音频信号传输与小功率供电需求,无需定制化设计即可适配多数标准设备。其典型应用场景包括:

  1. 便携式音频设备:MP3/MP4播放器、便携式蓝牙音箱、头戴式耳机的输入/输出接口;
  2. 移动终端:智能手机、平板电脑的耳机/麦克风二合一接口(兼容TRRS标准);
  3. 计算机设备:笔记本电脑、台式机前置/后置音频接口;
  4. 车载音频系统:车载中控的耳机输出接口、辅助音频输入接口;
  5. 小型电子设备:电子书阅读器、数码相框等的音频输出接口。

二、关键参数与核心性能特点

2.1 核心规格参数

  • 连接器类型:3.5mm标准耳机座(兼容TRS/TRRS音频插头);
  • 电气参数:额定电流1A(AC/DC)、额定电压30V(AC/DC);
  • 触头镀层:金(提升导电性能与耐磨擦性);
  • 工作温度:-30℃~+70℃(覆盖宽范围环境温度);
  • 封装形式:SMD贴片式。

2.2 性能优势

  • 稳定信号传输:金镀层触头接触电阻低(行业常规≤50mΩ),减少音频信号损耗,避免失真、杂音;
  • 宽适配性:1A额定电流满足音频电路小功率供电(如麦克风、耳机驱动),30V额定电压兼容多数音频设备工作范围,无需降额设计;
  • 高兼容性:3.5mm标准尺寸适配90%以上音频插头,无需担心接口不匹配。

三、封装形式与生产工艺细节

3.1 SMD封装优势

采用表面贴装封装,相比传统插件式:

  • 提升量产效率:自动化贴片机焊接,减少人工工序;
  • 节省PCB空间:封装紧凑(直径≤10mm),优化设备内部布局;
  • 降低虚焊风险:贴片工艺一致性好,减少接触不良。

3.2 工艺细节

  • 触头镀金:厚金镀层(≥0.3μm),均匀耐磨,可承受数千次插拔;
  • 壳体材料:耐高温工程塑料(PA66),工作温度内不变形老化;
  • 引脚设计:间距符合IPC标准,兼容主流PCB设计库,降低设计难度。

四、可靠性与环境适应性

4.1 环境适应性

工作温度-30℃~+70℃,覆盖:

  • 低温场景:北方冬季户外、低温储存;
  • 高温场景:夏季室内长时间工作、车载短期暴晒(≤70℃)。

4.2 可靠性指标

  • 插拔寿命:≥5000次(满足日常使用);
  • 绝缘电阻:≥100MΩ(100V DC),防止短路;
  • 耐温循环:-40℃~+85℃循环30次,无变形/接触不良。

五、品牌与品质保障

SHOU HAN(首韩)作为连接器专业品牌,该产品遵循:

  1. 环保合规:符合RoHS、REACH标准,无有害物质;
  2. 出厂测试:每批次经接触电阻、插拔、耐温测试,确保一致性;
  3. 售后支持:1年质保,批量客户可定制适配方案。

PJ-342 141凭借稳定性能、便捷生产适配性与高性价比,成为消费电子领域3.5mm音频接口的优选方案,可满足多数中小型音频设备的接口需求。

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.

Electronic component model and package intelligence review on an ESD-safe inspection bench

Model & package intelligence

Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.

BOM matching and alternative component comparison workstation with protected IC samples

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
