0.1mm thick SUS301 spring steel sheet

SUS301 spring sheet with a thickness of 0.1mm is ideally suited for the demands of modern electronics, which are trending toward slim profiles and high integration. It can withstand repeated bending and pressing without breaking easily, ensuring a long service life.

Description

0.1mm thick SUS301 spring steel sheet

Primary Applications
SUS301 with a thickness of 0.1mm (approximately 100 microns) is exceptionally thin, making it ideal for applications requiring minimal deformation, high precision, and high-frequency recovery.

Connectors and Electrical Contact Components: This represents the primary application.

Internal connectors for mobile phones/computers: Examples include battery connectors, FPC/FFC connectors, and SIM card tray springs. Its elasticity ensures stable electrical contact and sufficient insertion/extraction force.

Micro switches: Serves as the contact spring inside switches to complete or break circuits.

Precision mechanical components:

Micro spring sheets: Used in optical image stabilization mechanisms, camera modules, micro sensors, and other applications requiring minimal reset force.

Shielding Covers/EMI Spring Plates: Used to shield electromagnetic interference while providing grounding pathways. A thickness of 0.1mm ensures both elasticity and effective shielding.

Brake Plates/Positioning Plates: Employed in precision instruments or small devices for part positioning, limiting travel, or providing light friction braking.

Consumer Electronics:

Wearable Devices:
Spring connectors or structural fasteners within smartwatches and earbuds.

Hinge and Pivot Mechanisms:
Provide required torque and tactile feedback in flip phones and foldable devices.

Automotive Electronics:

Contact springs in automotive sensors and ECU connectors, demanding high reliability and vibration resistance.
