F0603E0R25FSTR Description

Short technical summary and product information.

The Kyocera AVX F0603E0R25FSTR is a surface-mount thin-film fuse from the Accu-Guard II series, designed for overcurrent protection in compact electronic circuits. It is rated for 250 mA continuous current at 32 V DC and features a fast blow response time, making it suitable for protecting sensitive components where rapid interruption of fault currents is required.

 

Electrical characteristics include a maximum resistance of 0.65 Ω at 10% of rated current and 25°C, a maximum voltage drop of 220 mV at rated current, and a fusing current of 0.625 A within 5 seconds. The pre-arc I²t is 5E-05 A²s, and the breaking capacity is 50 A at rated voltage. The fuse operates over a temperature range of -55°C to +125°C.

 

The device is housed in a standard 0603 (1608 metric) chip package with SMD solder pad termination, measuring 1.60 mm x 0.81 mm x 0.63 mm. It is RoHS3 compliant and REACH unaffected, with an MSL rating of Level 1 (unlimited).
