The EW-412 is a Through Hole Resistor manufactured by Asahi Kasei Microsystems (AKM). It's a passive electronic component designed to resist the flow of electrical current. Through-hole resistors are characterized by their leads, which are inserted through holes in a printed circuit board (PCB) and soldered on the opposite side.

Applications

• Current Limiting: Used to limit the amount of current flowing in a circuit.
• Voltage Division: Employed in voltage divider circuits to create a specific voltage level.
• Pull-Up/Pull-Down Resistors: Used to define the default logic state of a digital input.
• Load Resistors: Provide a load for a signal source, such as an amplifier.
• Filters: Used in conjunction with capacitors and inductors to create filters for signal conditioning.

Features

• Through-Hole Mounting.
• Fixed Resistance Value.
• Various Resistance Values Available.
• Standard Tolerance.
• Axial Leads.

Benefits

• Simple to Use: Easy to install and connect in electronic circuits.
• Reliable Performance: Provides stable and consistent resistance.
• Wide Availability: Readily available in various resistance values and tolerances.
• Cost-Effective: Economical component for current limiting and voltage division.
• Robust Construction: Capable of withstanding mechanical stress and environmental factors.

Additional Details

The EW-412's specific resistance value, tolerance, and power rating are critical parameters for proper circuit design. Common resistance values range from ohms to megaohms. Tolerance indicates the accuracy of the stated resistance value (e.g., 1%, 5%, 10%). Power rating specifies the maximum power the resistor can dissipate without damage, typically ranging from 1/8W to 1W for through-hole resistors. They are commonly made of carbon film, metal film, or wirewound materials. For critical applications, metal film resistors offer better precision and stability compared to carbon film resistors. Always consult the manufacturer's specifications for the exact resistance value, tolerance, power rating, temperature coefficient, and other relevant parameters for the EW-412 to ensure proper functionality and long-term reliability in the intended circuit.
