POLY-FUSE® 0603L series, PTC Resettable Fuse, polymeric, surface mount, 0603 (1608 Metric) concave package, 100 mA hold, 15 V max, 40 A max interrupt, 1 s trip time.","salesMarkdown":"## Device identity and key parametrics The 0603L010YR is a Littelfuse POLY-FUSE® series polymeric PTC resettable fuse in a standard 0603 (1608 Metric) concave surface-mount package. Rated for a hold current (Ih) of 100 mA maximum at 15 V, with a maximum interrupt current of 40 A — the device trips in 1 second at the specified fault condition. The initial cold resistance is 900 mOhms minimum, rising to 6 Ohms maximum after a trip event, which defines the series resistance added to the protected circuit. Occupies a 1.60 mm x 0.80 mm footprint with a maximum seated height of 0.75 mm — the concave termination style is compatible with standard reflow solder profiles for 0603 chip components. ## Temperature grade and compliance Carries cURus and TUV agency approvals, confirming the device meets North American and European safety standards for overcurrent protection components.","metaTitle":"Littelfuse 0603L010YR PTC Resettable Fuse, 100 mA, 15V","metaDescription":"Littelfuse 0603L010YR POLY-FUSE polymeric PTC resettable fuse, 100 mA hold current, 15V max, 0603 SMD.
