IR - IRF540N Transistor, N Channel MOSFET.

The IRF540 is an N-Channel Mosfet. This mosfet can drive loads upto 23A and can support peak current upto 110A. It also has a threshold voltage of 4V, which means it can easily driven by low voltages like 5V. Hence it is mostly used with Arduino and other microcontrollers for logic switching. Speed control of motors and Light dimmers are also possible with this Mosfet since it has good switching characteristics.

INTER-MARKET INC. - NE-1P - Lamps & Lights. Neon, Miniature Bulb. The INTER-MARKET INC. NE-1P is a miniature neon indicator lamp designed for use in electronic equipment and appliances. It functions as a gas-discharge lamp where a glass envelope is filled with neon gas (often mixed with argon) that glows when sufficient voltage is applied between its electrodes. Key Specifications & Features • Lamp Type: Miniature Neon Bulb. • Package Style: Radial Leads (wire terminals). • Common Use: Primarily used as a status or power indicator in line-voltage circuits. • Durability: Highly rugged and resistant to mechanical shock, vibration, and frequent on/off cycles. • Operating Temperature: Can operate in a wide range from -40°C to +150°C General Operating Characteristics While specific electrical ratings can vary by exact sub-model, typical neon lamps of this class share these traits: • Breakdown (Strike) Voltage: Usually requires 65–90V AC or 90–135V DC to initiate the glow. • Maintaining Voltage: Once lit, the voltage across the lamp typically drops by about 10–20V. • Current: Operates at very low current, typically between 0.5 mA and 3.0 mA. • Mandatory Resistor: A series current-limiting resistor is required for safe operation; without it, the lamp may shatter or damage the circuit. Recommended Resistor Values The exact resistance depends on your supply voltage and how bright you want the lamp to be: • For 120V AC (Standard US Mains): o Standard Brightness: Use a 100kΩ (100,000 ohm) resistor. o Extended Life/Dimmer: Use a 150kΩ or 220kΩ resistor. • For 220V–240V AC (EU/International Mains): o Standard Brightness: Use a 220kΩ to 330kΩ resistor. Power Rating (Wattage) • A standard 1/4 watt (0.25W) resistor is sufficient for both 120V and 240V applications, as the power dissipated by the resistor at these current levels is typically less than 0.1W. Installation Tips • Series Connection: Connect the resistor to either lead of the neon bulb. It must be in series with the lamp, not in parallel. • Insulation: Since you are likely working with mains voltage, ensure the resistor and all exposed connections are covered with heat shrink tubing to prevent electrical shock. • DC Operation: If using DC, only one electrode will glow. You may need to slightly lower the resistance value compared to AC to achieve the same brightness. Type: Vintage Neon, Miniature. Package: Radial Leads. Vintage - New Old Stock Learn More
