Frequently Asked Questions
Why does this Micro USB connector specify a 1A current rating instead of 2A?
This specific part (MUSB05F-78569) is custom-engineered according to strict drawing notes with a 1.0A max current limit, optimized for low-power signal transmission, diagnostic data logging, and standard battery trickle charging in sealed instruments.
How does the lack of locating pegs affect PCB assembly?
Omitting locating pegs allows for a flatter, space-saving PCB layout near the board edge. Automated SMT placement relies on the precise solder pad footprint and inner shell stakes for positioning and solder reflow anchoring.
What is the dielectric withstanding voltage specification for this component?
According to the official engineering drawing, the dielectric withstanding voltage is rated at 100V AC for 1 minute, paired with an insulation resistance of 100 MΩ minimum.
What is the verified durability life cycle of this connector?
The connector is rated for 10,000 full insertion and extraction cycles. The drawing guarantees a total unmating force between 0.81 Kgf and 2.05 Kgf even after 10,000 cycles, preventing loose cable connections over long-term field use.
What customization options does EDOM Electronics offer for OEM buyers?
As a direct manufacturer, we offer custom plating thickness on contacts, reel packaging options for automated SMT feeders, and full overmolded cable assemblies tailored to mate perfectly with this receptacle.
Overview and Application Notes
Overview: Engineered for compact electronic devices, the MUSB05F-78569 is a reliable Micro USB 2.0 female receptacle featuring a 5-pin single-row SMT configuration without locating pegs. Built strictly to engineering specifications, it utilizes a high-temperature thermoplastic housing reinforced with glass fiber (UL 94V-0) and high-conductivity copper alloy contacts (t=0.20mm) and shell (t=0.25mm). Rated for 1A maximum current and 100V AC dielectric withstanding voltage, this connector guarantees exceptional durability with a verified 10,000 mating cycle threshold across a -30°C to +80°C operating temperature range. Manufactured in our ISO-certified facility, it offers OEM/ODM equipment builders a dependable, space-saving I/O solution.
Application Notes:
-
No-Peg SMT Alignment: Because this connector design omits plastic locating pegs (without pegs), ensure your automated SMT pick-and-place equipment relies on precise optical alignment for the SMT pads and shell solder tabs.
-
PCB Footprint & Cutout: Strictly adhere to the recommended PCB layout (0.65mm pin pitch, 8.10mm outer tab span) for edge-mount solder pad positioning to guarantee mechanical retention.
-
Reflow Temperature Control: The glass-fiber filled high-temperature thermoplastic insulator is rated for standard lead-free SMT reflow profiles within the -30°C to +80°C working range.
