## Description

The Amphenol MCP IoT Antennas ST0812-11-N03-A is a specialized Flexible Printed Circuit (FPC) near-field communication antenna engineered for 13.56 MHz RFID, ticketing, and device-pairing applications. Featuring an integrated ferrite layer with a relative permeability of 150, this embedded antenna mitigates detuning effects caused by nearby metal enclosures or battery packs in space-constrained designs. The component is specified with a nominal input impedance of 30 ohms (ranging from 20 to 30 ohms) and an ultra-thin physical profile measuring 30 x 34 x 0.35 mm, allowing direct surface-mounting onto device housings, internal covers, or mechanical chassis.

Built for seamless integration into modern IoT hardware, payment terminals, and mobile devices, the ST0812-11-N03-A relies on an optimized inductive pattern designed to operate efficiently within standard 13.56 MHz carrier constraints when paired with an appropriate matching network and tuning capacitance (such as a 680 pF capacitor with a 5% tolerance). The semi-flexible FPC substrate ensures robust mechanical durability during assembly, while full RoHS compliance ensures adherence to current environmental safety directives for commercial electronic manufacturing.
