CN-0035 CN-0035 Change Notice TL Series Super Bright LED Specifications Type of Change: Engineering Product Part Number Appearance The TL Series has had modifications to the LED specifications for the super bright option. The changes are for the blue and green LEDs, and will affect standard and custom devices. Part numbers included in this change are: TL22DNAW016F (Green) TL22DNAW016G (Blue) TL22SNAG016F (Green) TL22SNAG016G (Blue) TL Illuminated Toggle LED Specifications ATTENTION Super Bright LED (+) ELECTROSTATIC SENSITIVE DEVICES (-) From Current LED Specifications To New LED Specifications 6B 6F 6G 6B 6F 6G White Green Blue White Green Blue Forward Peak Current I FM 30mA 30mA 30mA 30mA 30mA 30mA Continuous Forward Current IF 20mA 20mA 20mA 20mA 20mA 20mA Forward Voltage (I F = 20mA) VF 3.6V 3.3V 3.4V 3.6V 3.5V 3.6V Reverse Peak Voltage VRM 5V 5V 5V 5V 5V 5V Current Reduction Rate Above 25°C ∆I F Ambient Temperature Range 0.50mA/°C 0.40mA/°C 0.40mA/°C 0.50mA/°C 0.50mA/°C 0.50mA/°C –10°C ~ +55°C LED is an integral part of the switch and not available separately. The LED circuit is independent of switch operation. Electrical specifications are determined at a basic temperature of 25°C. If the source voltage exceeds rated voltage, a ballast resistor is required. The resistor value can be calculated by using the formula shown here. Notes: –10°C ~ +55°C R + IF Anode VF E Cathode – R = Where: R = E = VF = IF = E – VF IF Resistor Value (Ohms) Source Voltage (V) Forward Voltage (V) Forward Current (A) There is no change to the specifications of the white LED. There is no change to the dimensions of the switches. Due to the change of Forward Voltage (VF ), the external resistor value may be affected. Contact the factory if further details are needed. Availability TL Series with new LED specifications will be available with June 2009 production. www.nkkswitches.com 1.877.2BUYNKK 228.9655 Engineering Department 7850 East Gelding Drive • Scottsdale, AZ 85260 Telephone 480.991.0942 • Fax 480.998.1435 1/22/09
