RL series, low resistance value chip
resistors with long-side electrodes
for high-precision current detection.
A specially designed construction assures small dimensions and repressed surface
temperature increase due to heat radiation and thermal conduction. This construction also
minimizes the thermal effects on peripheral areas. Patent 2963671
Our SMD components contribute to lead-free composition of electronics products.
