0603L025YR Description

Short technical summary and product information.

The Littelfuse 0603L025YR is a PolySwitch PTC resettable overcurrent protection device from the 0603L series. It offers a hold current of 250 mA at 20°C still air, with a trip current of 0.55 A. The maximum voltage rating is 9 V DC, and it can withstand fault currents up to 40 A. At 8 A fault current, the device trips in 80 ms typical.

 

The device features low initial resistance of 0.5 Ω and post-trip resistance of 3 Ω, making it suitable for low-power applications. Power dissipation in the tripped state is 0.5 W typical. The operating temperature range is -40°C to 85°C.

 

Packaged in an 0603 (1608 Metric) concave surface mount package, the 0603L025YR measures 1.60 mm x 0.80 mm x 0.75 mm. The compact design conserves board space, ideal for space-constrained electronics. The device is RoHS compliant, halogen-free, and has a moisture sensitivity level of 1 (unlimited).
