Import 3.5 Headphone Audio Socket Patch Type — Buy in wholesale FOB from Supplier in China

The 3.5 Headphone Audio Socket Patch Type is a surface-mount or through-hole audio connector designed for PCB integration in consumer electronics, portable devices, and professional audio equipment. XKB Precision Technology (Shenzhen) Co., Ltd. rates this component at DC 12 V and 1 A, suitable for low-voltage signal paths in headphone and line-out applications. The 3.5 mm jack dimension follows the EIAJ standard for miniature phone connectors, with tip-ring-sleeve (TRS) or tip-ring-ring-sleeve (TRRS) configuration typical depending on variant. The source data does not specify whether this is a mono, stereo, or 4-conductor CTIA/OMTP variant, nor the exact PCB mounting orientation. The actuation force of 1-3 kgf indicates a moderate insertion feel, balancing retention security with user ease across repeated plugging cycles.

Material construction for patch-type 3.5 mm jacks typically employs phosphor bronze or brass alloy contacts with nickel underplating and gold flash or tin-over-nickel finish, though the specific contact material and plating thickness are not stated in the listing. The housing is generally LCP (liquid crystal polymer) or PBT (polybutylene terephthalate) for surface-mount reflow compatibility, with a rated reflow temperature of 260 degrees Celsius cited. This temperature rating aligns with lead-free solder profile peak temperatures, indicating RoHS-process compatibility. The -40 degrees Celsius to +80 degrees Celsius operating range covers industrial and consumer applications, though humidity and salt spray resistance ratings are absent. The 10,000-cycle mechanical life is standard for mid-tier consumer connectors, premium audio jacks may offer 5,000-50,000 cycles depending on contact design and plating quality.

Buyers for this component include OEMs manufacturing portable media players, smartphone accessories, gaming headsets, medical monitoring devices, and industrial audio interfaces. The patch type designation suggests a horizontal or vertical PCB mounting with solder tabs rather than threaded panel mount, though exact footprint dimensions and pinout are not provided. XKB Precision Technology (Shenzhen) Co., Ltd. is located in Dongguan, Guangdong province, a major electronics manufacturing cluster. The listing does not state minimum order quantity, price, lead time, or available packaging (tape and reel, tray, or bulk). Buyers should request the mechanical drawing, 3D step file, and sample pinout schematic to ensure PCB layout compatibility before prototype integration.

XKB Precision Technology (Shenzhen) Co., Ltd. maintains its registered address at No. 3 Second Hongye North Road, Dongguan 523710, Guangdong, China. The company name references Shenzhen, though the operational and registered address is in Dongguan, a distinction buyers should clarify regarding actual manufacturing location versus administrative registration. The supplier holds a harbor trust tier with a response rate that is anonymised and average response hours listed at zero, indicating limited recent platform activity. Direct communication channels should be tested for current responsiveness before relying on platform messaging alone.

The listing provides product-specific technical parameters but no company history, factory size, certification portfolio, or key account references. No ISO 9001, IATF 16949, or IPC membership is mentioned in the source data. The product category suggests capability in precision connector manufacturing, though the extent of in-house moulding, stamping, and plating operations versus trading or assembly is not disclosed. Buyers should request a factory profile, quality policy documentation, and evidence of process controls specific to audio connector production. The address in Dongguan places the supplier within the Pearl River Delta electronics manufacturing corridor, providing logistical access to Shenzhen port and surrounding component supply chains.
