Predoxraniteli serii 243 ot BETTERFUSE

The CHIP and DIP range has been expanded with 243 series fuses from BETTERFUSE.

The 243 series fuses have a ceramic smd housing with a square cross-section of size 2410 (6.1×2.8×2.8 mm). These fuses are manufactured using lead-free technology. In addition to their small overall dimensions, they have a wide range of rated currents (from 160 mA to 40 A), a wide range of operating temperatures (from -55 to +125°C) and a low temperature rating (limiting the permissible current relative to the nominal value due to the correction for ambient temperature).

The 243 series belongs to the Fast Acting (F) category of high-speed fuses. The fuse operation time, when the current flowing through it exceeds 200% of the nominal value, is no more than 5 seconds. The operating voltage of the 243 series does not exceed 125 V.
