Product Description
Compact 5.5×2.1 mm DC power socket designed for 3C digital products (computers, communications, consumer electronics). The standard barrel size ensures broad compatibility with mainstream power adapters, while a robust housing and precision spring contacts provide firm retention, low contact resistance, and stable DC input. Available in PCB and panel‑mount variants to suit diverse product layouts.
Key features and specifications:
- Interface: DC barrel jack, outer Ø5.5 mm, inner pin Ø2.1 mm; supports common plug lengths (9.5/11/12 mm, model‑dependent)
- Electrical rating: typically 5–24 V DC; up to 3–5 A depending on model and thermal design
- Termination options: right‑angle or vertical through‑hole (THT), SMT versions, and panel‑mount types with solder lugs
- Contact system: copper‑alloy contacts with nickel/tin plating for low resistance and reliable power transfer
- Housing: high‑temperature PBT/PA66, UL94 V‑0 flame rating
- Durability: ≥5,000 mating cycles; stable retention force
- Environmental: operating −25 to +85 °C; optional dust cap/gasket (model‑dependent)
- Polarity: center‑positive typical (confirm application)
- Compliance: RoHS and REACH
Optional functions:
- Built‑in normally‑closed switch contact to disconnect internal battery/rail when a plug is inserted
- ESD/EMI mitigating design and reinforced solder anchors for improved drop/vibration resistance
Applications:
Wi‑Fi routers, set‑top boxes, streaming devices, portable speakers, mini PCs, monitors, handheld instruments, LED lighting controllers, smart home hubs, and other 3C digital products.
Notes:
Verify plug length standard, footprint, pinout, and exact current/voltage ratings for the selected model before design‑in. Packaging available in tape‑and‑reel (SMT) or tray/bulk (THT).
