KT-0603R

The Hubei KENTO Elec KT-0603R is a red surface-mount LED in a standard 0603 (1608 Metric) package with dimensions of 1.6 mm × 0.8 mm × 0.6 mm. It features a transparent planar lens, is compatible with SMT automatic assembly and infrared reflow soldering processes, and complies with RoHS requirements. At a test current of 20 mA, the device provides a dominant wavelength of 615–630 nm, a forward voltage of 1.8–2.4 V, a typical viewing angle of 120°, and luminous intensity ranging from 145–300 mcd, depending on the selected bin.

The KT-0603R has a forward voltage of 1.8–2.4 V at a forward current of 20 mA. The maximum continuous forward current is 25 mA, the peak forward current is 60 mA (0.1 ms pulse, 1/10 duty cycle), and the maximum reverse voltage is 5 V. The manufacturer recommends operating the LED at its rated current and using a current-limiting resistor in the circuit to prevent excessive current that could damage the device.

The KT-0603R has an operating temperature range of −40°C to +85°C and a storage temperature range of −40°C to +85°C. It is a RoHS-compliant surface-mount LED designed for automated assembly using standard lead-free reflow soldering processes. Long-term reliability depends on operating the device within the specified electrical and thermal limits and following the manufacturer's recommended handling, soldering, storage, and ESD protection practices.

The KT-0603R is supplied in EIA standard tape-and-reel packaging for automated SMT assembly. The standard packing quantity specified by the manufacturer is 4,000 pieces per reel. The product is packaged in an anti-static, moisture-proof aluminum foil bag to help protect the devices during storage and transportation.

The KT-0603R is compatible with standard lead-free infrared reflow soldering processes with a maximum reflow temperature of 260°C for up to 10 seconds. Manual soldering is recommended only for repair or rework, with a maximum soldering temperature of 300°C for no more than 3 seconds, and only one manual soldering operation should be performed. During assembly, excessive mechanical force on the LED lens should be avoided, the PCB should not be bent after soldering, and appropriate ESD precautions should be followed to prevent device damage.
