CRD S series products are surface mount devices that come in resin-sealed SMD package.
– Added the S-183 (18 mA) targeted for high brightness LEDs to our lineup
-Rated power increased to 500 mW, to expand voltage range and improve constant current characteristics
– Lowered mounting height, facilitating use in low profile products
– About the same height as the latest low profile LEDs so that when mounted next to each other, light will not be blocked off
18mA CRD (S-183)
With the addition of an 18mA CRD to our product lineup (from 15mA), it is now possible to supply constant current to 20mA high brightness LEDs for luminance stabilization.
Applications
- Constant current source for LED brightness stabilization
- LED street lights, LED fluorescent lamps, LED light bulbs, LED downlights
- Constant voltage circuit for supplying constant current to Zener diodes
- Constant current source for proximity sensors and other sensors
- Battery charge / discharge circuits
- Electrolytic capacitor aging equipment
- Constant current test equipment for various semiconductor devices
- Telecommunications line interface
- Earth leakage circuit breakers
- Current source for piezoelectric actuators
- Stabilized power supply circuits
