If the source voltage exceeds the rated voltage, a ballast Maximum Forward Current I 25mA FM resistor is required. The following diagram and formula will assist in calculating the value of the ballast resistor. Typical Forward Current I 20mA F Forward Voltage V 2.1V F E V R I F + F R = I Anode F Maximum Reverse Voltage V 5V RM Where: R = Resistor Value (Ohms) E V F E = Source Voltage (V) V = Forward Voltage (V) F Current Reduction Rate Above 25C I 0.46mA/C Cathode F I = Forward Current (A) F Ambient Temperature Range 25C ~ +50C Base Switch Specifications Electrical Capacity (Resistive Load) Power Level: 5A 125/250V AC or 5A 30V DC Other Ratings Contact Resistance: 50 milliohms maximum Insulation Resistance: 200 megohms minimum 500V DC Dielectric Strength: 1,000V AC minimum between contacts for 1 minute minimum 1,500V AC minimum between contacts & case for 1 minute minimum Mechanical Life: 200,000 operations minimum Electrical Life: 10,000 operations minimum 100,000 operations minimum with resistive load of 3A 125V AC Nominal Operating Force: 1.9N Contact Timing: Break before make Travel: Pretravel .067 (1.7mm) Overtravel .024 (0.6mm) Total Travel .091 (2.3mm) Materials & Finishes Housing/Bezel: Glass fiber reinforced polyamide (UL94V-0) Snap-in Frame: Stainless steel Movable Contactor: Phosphor bronze Movable Contacts: Silver alloy or copper with gold plating Stationary Contacts: Silver alloy or copper with gold plating Switch Terminals: Phosphor bronze with silver or gold plating Lamp Terminals: Brass with silver plating Base: Glass fiber reinforced liquid crystal polymer (UL94V-0) Environmental Data Operating Temperature Range: 25C through +50C (13F through +122F) Humidity: 90 ~ 95% humidity for 96 hours 40C (104F) Vibration: 10 ~ 55Hz with peak-to-peak amplitude of 1.5mm traversing the frequency range & returning in 1 minute 3 right angled directions for 2 hours 2 Shock: 50G (490m/s ) acceleration (tested in 6 right angled directions, with 5 shocks in each direction) RoHS Compliant: Installation Cap Installation Force: 7.55N (1.70 lbf) maximum downward force on cap Soldering Time & Temp: Manual Soldering: 390C for 4 seconds, 2 cycles Cleaning: These devices are not process sealed.
