CONN RCPT Type-C 16POS SMD R/A The TYPE-C 16PIN 2MD(073) is a surface-mount USB Type-C receptacle connector commonly manufactured by SHOU HAN. It is designed for compact PCB applications requiring USB 3.1-compatible data transfer and 5V power delivery in consumer and industrial electronic devices. This connector uses a 16-pin optimized footprint (instead of the full 24-pin USB-C standard) where some contacts are internally shorted or omitted depending on application, making PCB routing simpler while still supporting basic USB-C functionality. USB Type-C female receptacle 16-pin reduced-layout configuration Supports USB 3.1 data transmission (application dependent) 5V rated voltage operation 3A–5A current capability (model dependent variant) Surface-mount (SMD), right-angle / horizontal mount Compact design for high-density PCB layouts Reversible plug orientation support (USB-C standard) Operating temperature: -25°C to +85°C Typical durability: ~5,000–10,000 mating cycles RoHS compliant, lead-free construction #CommonPartsLibrary #Connector

OR Controller N+1 ORing Controller N-Channel N:1 6-DFN (2x3) The LTC®4359 is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. It controls the forward-voltage drop across the MOSFET to ensure smooth current delivery without oscillation even at light loads. If a power source fails or is shorted, a fast turn-off minimizes reverse current transients. A shutdown mode is available to reduce the quiescent current to 9μA for load switch and 14µA for ideal diode applications. When used in high current diode applications, the LTC4359 reduces power consumption, heat dissipation, voltage loss and PC board area. With its wide operating voltage range, the ability to withstand reverse input voltage, and high temperature rating, the LTC4359 satisfies the demanding requirements of both automotive and telecom applications. The LTC4359 also easily ORs power sources in systems with redundant supplies - Reduces Power Dissipation by Replacing a Power Schottky Diode - Wide Operating Voltage Range: 4V to 80V - Reverse Input Protection to – 40V - Low 9µA Shutdown Current - Low 150μA Operating Current - Smooth Switchover without Oscillation - Controls Single or Back-to-Back N-Channel MOSFETs - Available in 6-Pin (2mm × 3mm) DFN, 8-Lead MSOP and 8-Lead SO Packages - AEC-Q100 Qualified for Automotive Applications #CommonPartsLibrary #IntegratedCircuit #PowerManagement #OR-Controller
