PJ-320D TT是首韩(SHOU HAN)品牌推出的一款小型化3.5mm音频连接器,采用表面贴装(SMD)封装设计,专为消费电子、便携设备的音频信号传输场景优化,兼具通用性、可靠性与生产适配性。以下从核心规格、性能特点、应用场景等维度展开详细说明。
PJ-320D TT定位于中低端消费电子音频接口,核心规格覆盖音频传输的基础需求,具体如下:
采用无引脚贴片设计,可直接通过回流焊工艺焊接到PCB板,无需额外插件工序,大幅提升电子设备生产效率,降低人工成本。
内置防尘盖结构(可选),防止灰尘、碎屑进入触头区域,延长使用寿命;银镀层表面经过钝化处理,抗氧化能力优于普通镀锡触头,长期使用后接触电阻无明显上升。
壳体采用耐高温ABS+PC合金材料,可承受回流焊峰值温度(250℃~260℃),无变形、开裂风险;同时具备一定抗冲击能力,适配便携设备的跌落场景。
PJ-320D TT因尺寸紧凑、性能稳定,广泛应用于以下领域:
产品出厂前需通过多项可靠性测试:
首韩(SHOU HAN)作为国内专注音频连接器的制造商,产品通过ISO9001质量管理体系认证,PJ-320D TT具备以下品质优势:
综上,PJ-320D TT以高通用性、低生产成本、稳定性能为核心优势,是消费电子领域3.5mm音频接口的高性价比选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
